Tight Buffered Distribution Cable

Internal cable for installation in trunking, under floor or ceiling spaces Fibre backbones in riser and horizontal configurations. The tight buffered internal distribution cables are constructed of 900μm buffered fibres surrounded by water swelling e-glass strength members jacketed in an LSZH outer jacket for moisture protection.

The OM3 50/125 Laser Enhanced cable is ideal for High Bandwidth requirements. The OM3 allows for VCSEL laser based hardware to coexist with old legacy LED. It also give a simple migration path through 1Gbps to 10 Gbps.
