Trang 3The continuing development of bandwidth
has seen growth from 10Mb/s to 1G/s in 15
years It is interesting to note that the biggest
growth, 100Mb/s to 1Gb/s, occurred in the last
4 years
A major cause of this explosion in bandwidth
has been the increase in dependency on the IT
platform, including the increasing use of the
Internet not only as a research tool but as a very
cost effective communication platform
The use of e-mail as a primary means of
communication, both within the organisation
and between organisations, has also contributed
to the increase in bandwidth requirement As
e-mail is archived for record keeping purposes,
mail storage services and mail retrieval adds to
the bandwidth demand
The growing trend towards Voice over Internet
Protocol (VoIP) requires IP infrastructure with low
latency characteristics High bandwidth provides
this in a relatively cost effective manner
As a result of the above we have seen the
development of the next generation of Ethernet
protocol - that is 10G capability
Around 12 months ago the 10G standard was
ratified by the IEEE, with fibre being the medium
of choice This facilitated the deployment of 1G
to the desktop with 100/1000/1G NIC cards
being readily available from most Vendors
The cost of infrastructure has always been an
issue, and it is becoming an even greater issue as
IT Mangers are expected to achieve
technological results that service the business’ IT
requirements as cost effectively as possible
Gone are the days of ‘Technology for
technology’s sake’
The IEEE is also conscious of ‘technology cost’
versus ‘real technology deliverables’
IEEE guidelines state that for new projects,
such as 10G/T, the new technology must deliver
10 times the deliverable of the technology it is
replacing for no more than 3 times the cost
So, the bandwidth demand marches on and the work on 10G over copper continues…
The IEEE 10G/T Study Group has set a time line for the Standard development, which should see
a Standard published around June 2006
Much debate is centred around the medium of choice that the Study Group is recommending
The group suggests Cat 6 cable will provide the most appropriate foundation for 10G/T implementation This is based on both economic and technological considerations
This technology is not about to overtake us all just yet The work of the IEEE, TIA and ISO is still very much in the initial stages A lot of work still needs to be done with encoding schemes and frequency requirements These are just two major technology challenges to be addressed
Not withstanding the above, the deployment
of this technology is well within the life expectancy of a structured cable solution that is ether being considered, designed or even installed today
My advice here is to use KRONE Contractors and Endorsed Installers trained in the Master Designer Course We are working towards providing people who can design a solution for the future, today Q

Trang 4ISO/IEC 11801 Ed.2 2002 Information technology – Generic cabling for customer premises
This standard is published It defines Classes of performance using categories of components Eg, Class D uses Cat 5 components, Class E uses Cat 6 components, Class F uses Cat 7 components
Category 3 (100 W and 120 W)), Category 4 (100
W and 120 W and 150 W) cabling components have been removed and Category 6 and 7 requirements have been included
Performance levels are given for Horizontal permanent link & channels and Backbone permanent links & channels Formulas are provided to de-rate cable lengths to allow for temperatures above 20° C
This standard has won awards as being one
of the best documents recently written and interestingly, some North American vendors are using ISO 11801 as their preferred standard for permanent link and channel performance levels
TIA/EIA 568-B1, B2, B3 The North American Telecommunications Standards
TIA/EIA 568-B1, B2, B3 The North American
Telecommunications Standards are now harmonised with the International ISO/IEC 11801 standard The main differences are that the North Americans still talk in terms of “Categories” of performance, eg Cat 5 & Cat 6 permanent links and channels, instead of Classes of permanent links & channels Cat 7 (Class F) has not been included in the 569-B series of standards
AS/NZS 3080 (Interim): 2002 Telecommunications installations - Generic cabling for commercial premises
This is a copy of ISO/IEC 11801 with some appendices that refer specifically to Australian and New Zealand practices Now that ISO
11801 has bees ratified and published, the
“interim” status will be lifted off AS/NZS 3080 and it will become a full standard It will be re-published during 2003
AS/NZS 3084: 1993 Telecommunications installations - Telecommunications pathways and spaces for commercial premises
The standard has been completely revised based
on revisions to ISO/IEC 18010 for the main body
It has been an extremely busy period for the committee that make
up the Telecommunications Industry contribution to Australian and International Standards.
STANDARDS UPDATE
by Peter Meijer, JP BE
MSc, RCDD,
Technical Training
Manager and Industry
Liaison,
KRONE Australia
KRONE considers that OH&S is a
vitally important issue for the
communications industry When an
issue arises that affects all cablers it is
better to talk too much than too little
- this is such an issue
The 1997 version of ACA TS 008
contained clauses that resulted in:
…”Underground conduit/pipe shall
be coloured white or contain a white
stripe as part of the extrusion
Furthermore … “conduit shall be marked
with the word ‘Communications’ … at
2 metre intervals
These rules make obvious sense to anyone who has had to dig up an underground conduit for repairs or replacement We all know that you don’t cut through the “Orange”
conduit because of the serious risk of death by electrocution But what if someone put a power cable in an unmarked white conduit? Yes, these
do exist I’m sorry to say
To make it even more difficult, sometimes white conduit that has been underground for some time has
a confusing “Grey” look about it So
the word “Communications” on the conduit is as important as the white colour Remember, it may be you who has to cut through the next white/grey conduit on a refurbishment site
The Communications Industry’s only recourse is to insist on, and always install underground conduit as White with the word “Communications” every 2 metres
KRONE not only supports these sensible rules, but insists on their compliance for all KRONE sites Q
COMMUNICATIONS CONDUIT
Where have the sensible marking rules involving underground conduit gone to?
Trang 5of the standard, with useful appendices based on
TIA/EIA 569A AS/NZS 3084: 2003 has been voted
on and approved and should be available next
month It will be of tremendous importance to
those responsible for ensuring adequate cabling
pathways and spaces for telecommunications
rooms, entrance facilities and the like The
performance of installed Class E channels using
Cat 6 components all starts from this standard
AS/NZS 3085.1: 1995 Telecommunications
installations - Administration of
communications cabling systems Part 1:
Basic requirements
The standard has been fully revised and was
submitted for public comment in March 2003
The comments are presently being reviewed and
resolved by the Standards Committee and the
revised standard should be published shortly It is
based on ISO/IEC 14763-1 and has also
considered the content of the TIA/EIA 606A
AS/NZS 3086: 1996 Telecommunications
installations – Integrated telecommunications
cabling for small office home office
The international version of this standard ISO/IEC
15018 is being updated and will be voted on by
the international committee in May 2003 It is
expected that the AS/NZS 3086 will like-wise be
updated possibly later this year or early next year
AS/NZS 3087: 2000 Specification for the testing of balanced communications cabling
This testing standard is a copy of ISO/IEC
61935-1 and the Australian 2000 version is being revised and updated to match the performance requirements set out in AS/NZS 3080: 2002 The public comment period closed on 1 April 2003 and it will be published in the near future as AS/NZS 3087.1 The standard relates more to laboratory testing than to field testing, although field testing is certainly covered Work is also in progress on an extra standard ISO/IEC 61935-2 dealing with Patch Cord Testing Again this is intended for laboratory testing use only and it will eventually be published as AS/NZS 3087.2 Patch Cord Testing Work is also progressing on a standard for the field testing Fibre Optic Cable installations and it will be published as AS/NZS 3087.3
HB29: 2000 Communications Cabling Handbook – Module 2
This useful handbook incorporates information from numerous Australian/New Zealand Standards and is intended to provide communications field installation staff with an easy to read guide HB29 is to be revised to bring
it into line with all the recent changes in the standards mentioned above It may be the end of this year before this work is complete Q
The launch turned out to be one of the most
successful KRONE has ever experienced in
Adelaide There were more than 70 people in
attendance including Consultants, Installers,
Distributors and End Users
Several KRONE staff members made the
journey west from Head Office and were
surprised by the turnout and the enthusiasm of
the South Australians
Commenting on the event, Jon Vause,
Western Region Sales Manager, said that
Adelaide is quite often starved of information that is readily available in the Eastern States
“There are not a lot of company’s that make the effort to go to Adelaide when launching a new product I always find that the South Australians appreciate the sharing of information, probably more than any where else
in Australia”
The last seminar KRONE held in Adelaide was
in May 2002 when the Optical Access range was released Q
HIGHBAND 25 HEADS WEST
Following on from the successful launch on the East Coast, KRONE
launched the HIGHBAND 25 system in Adelaide on the 20th March.
Trang 6Thiess Pty Ltd, one of the leading integrated
engineering and services providers in Australasia, has selected a KRONE GLOBAL LEADER solution featuring the new HIGHBAND®
25
As Thiess’ network demands escalated it found it was running out of network capacity at its head office facility, located in Brisbane’s Southbank Thiess made the decision to upgrade its existing communications infrastructure to Category 6 - enabling it to run Gigabit ethernet
“We were at a stage where there was no room available for additional 19” racks and the HIGHBAND 25, being a wall-mounted system offered the most efficient use of the available space,” said Anthony Mahoney, Telecom-munications Systems Engineer, Thiess
“Whilst we considered a number of alternative solutions we decided KRONE was the best choice for the task because of its flexibility and density
KRONE also was selected based on our prior use
of and exposure to the product
“The HIGHBAND 25 enabled us to free-up valuable 19” rack space in the communications room, which in turn allowed for the extra active equipment required.”
The HIGHBAND 25 solution is a high-density Category 6 cross-connect solution It is the only cross-connect solution on the market with a
disconnect feature, allowing for Patch-by-Exception (PBE)
“The installation is part of major upgrade to our existing network We selected a KRONE Category 6 GLOBAL LEADER solution to ensure that our communications infrastructure would provide the performance we required, both now and into the future
“We have installed a Cisco 6513 switch and the Category 6 solution ensures that the switch can operate to maximum capacity”, said Mr Mahoney
KRONE certified installer, Brisbane Data Services [now a part of Allied Technologies Group], was commissioned by Thiess to carry out the installation Brisbane Data Services has a long-standing relationship with Thiess, in fact they installed a KRONE Category 5 solution in the original site at Archerfield 12 years ago Harry Tucker, Manager, Brisbane Data Services said, “We recommended the HIGHBAND 25 solution because it was new technology It offered true category 6 performance whilst allowing for Patch-by-Exception, keeping the overall costs down whilst still providing full pair-management functionality
“The fact that the HIGHBAND 25 system is wall mounted meant that it offered the most efficient use of the available space It also allows future planned expansion of the comms room
“In the event that Thiess outgrow the current comms room – expanding will be as simple as unscrewing the HIGHBAND 25 backmounts, removing the existing wall and swinging the connected backmounts and modules onto the existing side wall, eliminating the need for re-cabling or re-connection”, said Mr Tucker
A weekend cut-over was required, as the whole computer room needed to be shut down
Thiess - first in Australia to utilise the KRONE HIGHBAND 25 technology

Trang 7Extensive pre-planning to ensure as much as
possible was done in advance allowed for a
successful completion of the project
“Our experience of working with KRONE in the
past meant there were no unexpected
implementation issues and everything went as
planned”, said Mr Mahoney
The installation consisted of four 900pr verticals
and associated cable management equipment
This was used to connect all of the active
equipment An allowance was made for two
additional verticals to be added when required In
addition to the HIGHBAND 25 system, 360
KRONE KM8 jacks were connected to fifteen
24-port patch panels
One of the major benefits of the PBE solution is
the reduction in the number of patchcords used
As a result, the mess of patch cords often
associated with other pair managed solutions is
eliminated
“With the HIGHBAND 25 system, there are
fewer faults because it is hard-wired and not
patched, and fault finding is much easier
Patching is quicker, which saves time
“This system services the entire operations
group Each member of the group is at some time
required to make changes Our time is at a
premium The HIGHBAND 25 system makes
moves, adds and changes easier, the labelling
system means that record keeping is easy – saving
us all time,” said Mr Mahoney Q

Trang 8Hong Kong has one of the highest broadband take-up ratios in the world According to OFTA, the telecommunications regulator, there were 1,009,426 broadband subscribers at the end of Jan 2003– an increase of more than 40 per cent over the figure reported a year earlier
Dial-up numbers have been dropping steadily with the advance of broadband
In 1999, Hong Kong Broadband Network Limited (HKBN) decided the time was right to capitalise on this growing market
Being a wholly-owned subsidiary of City Telecom (HK) Limited (CTI), HKBN is one of Hong Kong’s leading fixed network service providers in Hong Kong Its mission is to provide customers with advanced, reliable and economical fixed network services such as broadband Internet access, local telephony and digital television
HKBN has invested approximately HK$1 billion
to develop its network infrastructure In three years HKBN has achieved the goal to cover 1.2 million homepass, representing 60% of the local Hong Kong SAR households by the end of 2003
At the outset, HKBN assessed the broadband market and decided to take a different approach from its competitors Rather than focusing on content provision and e-commerce, the company decided that the key to success was in the infrastructure itself
As a result, they set to work building a next-generation network, based on state-of-the-art Internet Protocol, that would be technologically advanced, robust and extremely scalable It also had to be feature-rich to enable HKBN to offer
Internet data, voice and digital TV services over the same network, and it had
to provide plenty of headroom to match HKBN’s aggressive expansion plans
”We didn’t just want a
t e l e c o m -munications infrastructure that was ‘good enough’, we wanted
it to be the best,” said Ricky
Wong, Chairman of CTI and HKBN “With a project of this magnitude and importance to our company we needed a network based on the best technology available today.”
Terry Lee, General Manager of KRONE Hong Kong added, “Broadband access is now pivotal
to the provision of next-generation networks and telecom carriers and service providers are making huge financial investments to build and deploy state-of-the-art backbones and infrastructure to support this.”
”They are using various technologies and streaming techniques to move content closer and closer to the edge of the network These next generation networks provide massive core capacity but the challenge is the local loop bottleneck – the ability to deliver broadband to customers over the last mile.”
Next generation networks of this scale typically comprise best-of-breed components from a number of specialist vendors The HKBN network is no exception When it came to specifying wire termination blocks – of which HKBN would need literally thousands – HKBN turned to KRONE, a leading manufacturer of cable and connectivity products for public and private networks
Delivered in kit form, KRONE’s HIGHBAND 10 wire termination blocks are ideal for custom solutions in the fast growing xDSL and broadband sectors Meeting Enhanced Category (C5e) specifications, they include proven, reliable 45-degree angle silver-plated contacts for less wire stress and stronger hold, and feature a unique centre port for testing and patching
”The centre port provides an efficient ‘look both ways’ testing capability to quickly pinpoint problems on either the service provider or customer side,” said Lee “The blocks also save time and labour when connecting, discontinuing
or re-assigning service – all without disconnecting any wires.”
HKBN started to implement the KRONE Broadband Connectivity solution in 2001 Since then it has installed 500,000 HIGHBAND 10 modules covering more than 100 buildings and its central offices
The HIGHBAND 10 module can carry a broadband signal up to 350MHz - ADSL is
By mid-2002, Hong Kong's total Internet subscriber population was estimated at 2.6 million, of which 1.8 million were using dial-up connections.
TODAY’S CONNECTIVITY
TOMORROW’S

Export Manager
KRONE Australia
Trang 9currently only delivering up to 8MHz KRONE
Hong Kong supply the HIGHBAND 10 in kits of
200- or 300-pairs The field terminated
assemblies are shipped in a complete package
that includes wire termination blocks, mounting
hardware, labelling modules and numbered
inserts to quickly identify pairs
The 10-pair increment of the blocks makes it
easy to match large pair-count cables of 50, 100,
300 or greater pairs When combined with
KRONE’s enhanced performance DS1 cable,
providers achieve a complete Broadband/DSL
solution
”One of the key features that makes
installation quick and easy is KRONE’s insulation
displacement contact, or IDC connectors,” said
Lee “With this technology, connections are
more reliable, more durable and can be made
much faster.”
Delivering on its vision of building “the best”
network, HKBN has deployed a robust,
cost-effective infrastructure It is both future-proof,
meaning that it can scale easily as extra capacity
is required, and it delivers a high quality of
service because it reduces NEXT (Near End Cross
Talk) at higher frequencies
”NEXT disturbance takes place when the
electric or magnetic field of one
telecommunication signal affects a signal in an
adjacent circuit This can cause severe
degradation in transmission,” said Lee
”Our HIGHBAND 10 modules ensure a greater
quality of signal and therefore less
re-transmission which means a better return loss
performance Even a few dB of additional
channel headroom has significant implications in
terms of maximum channel reach It can have a
big impact on overall network rollout costs.”
The deployment of KRONE’s HIGHBAND 10
modules is now almost complete However,
KRONE expects to see steady demand as HKBN
develops more diversified services such as pay-TV
over the network, and the number of subscribers
increases
Having successfully migrated from a reseller of
56K dialup Internet access services to become a
fixed network operator, HKBN is delivering on its
vision of deploying the world’s largest metro
Ethernet network
”By the end of 2004, we expect the number
of installed modules to be in excess of 500,000,”
said Lee “HKBN has established the world’s largest metro Ethernet network and we are delighted to be playing a part in turning this vision into reality.”
KRONE’s ability to provide high-quality components and designs has made it an obvious choice for next-generation networks In fact today, all of Hong Kong’s carriers use KRONE as connectivity supplier
To help global telecommunications providers support new applications and solve the challenges posed by last/first mile bottlenecks, KRONE has developed a new Broadband family
of products
Differentiated by its distinctive purple colour, this new range complements the company’s classic HIGHBAND modules, providing customers with “end-to-end” broadband connectivity Q

The Norwegian Dawn measures 298 metres, has 15 decks and weighs more than 91,000 gross tonne
Purpose built for Freestyle Cruising from Miami to the Caribbean, and from New York to the Bahamas and Florida, the Norwegian Dawn accommodates more than 2,000 passengers and 1,300 crew
Closed circuit television cameras were installed on-board the Norwegian Dawn, by Empire Automation to provide security for passengers and crew against vandalism, illegal and anti-social behaviour and fire safety
Empire Automation installed 780 closed circuit television cameras (24vac) throughout the vessel cabled to seven locations around the ship Each camera had a composite cable run to it The composite cable consisted of a 2 core 1.5mm power cable; one 4 core screened data cable, and one RG59 coaxial cable The seven remote
termination locations were connected to the surveillance monitoring room via fibre optics
The KRONE TERMINATOR System was used for connecting and fusing camera power supply circuits, resulting in more than 3,000 wire terminations
The TERMINATOR System is based on the KRONE Insulation Displacement Connection (IDC) technique, which requires no stripping or screwing Using a simple tool wires are inserted between contacts placed at a 45-degree angle, which simultaneously displace the insulation and notch the conductor
This method leaves more conductors between contact points and provides a more reliable connection Screwless terminations also overcome the potential risk of failing to tighten the screw correctly, a common cause of terminal failure The constant high contact pressure is maintained during severe vibration and shock conditions
As space was at a premium KRONE’s TERMINATOR System, with its modular, high-density design was ideal Standard, commercially available camera power termination systems were not suitable, as they require a lot of wall or rack space
The KRONE TERMINATOR System saved time for Empire Automation as well as producing reliable connections
The Norwegian Dawn was launched in December 2002 as the newest addition to Norwegian Cruise Lines’ luxury fleet
