Applications

Superior reliability and ruggedness make 3M™ Glass/Glass/Polymer (GGP) fiber optic cable

assemblies ideal for applications requiring tight bends, durability and dependability.

3M GGP cable assemblies use 3M’s proprietary Glass/Glass/Polymer fiber that has superior

mechanical performance compared to standard fiber This makes GGP cable assemblies ideal

for panel-to-panel cross-connects, equipment back planes, under desk and other applications

that require reliability and mechanical strength

The glass cladding around the core is reduced in size and surrounded with a permanent and

protective polymer coating, resulting in a standard 125µm fiber diameter This provides a

quality connection to standard fibers GGP Cable Assemblies are also available with optional

shutters connector assemblies for protection against accidental laser exposure and dust

The rugged and durable 3M GGP cable assembly is the perfect solution for optical patching

application where high level of bending and stress is expected.

Glass-Glass-Polymer structure in 125µm Standard 125µm fiber diameter

Tight bend radius and high bending strength Increased durability and reliability for tight, confined spaces Telecommunication, remote ONU & FTTx

Cable flexibility Easy to manage and route through tight bends Fast Deployable Local Area Network
