6.1 Cleaning

The connector design allows easy access for cleaning of the optical end faces With the connectors unmated

the process for cleaning should include:

a) With the contacts remaining in the connectors use a lint free tissue or cleaning probe wetted with a

suitable accepted cleaning solution to wipe the end face of the contacts

b) Remove excess cleaning fluid with an aerosol free agent s.a dry air

c) Mate the connector halves
