Fiber Optic Cable

Data can travel much farther over fiber optic cable than over Category 3, 4 or 5 cable. Cable length can be up to 1.25 miles (two kilometers) in full duplex and 1350 feet (412 meters) in half duplex transmitting at 100 Mbps.

Fiber optic cables connected to the fiber expansion module for 100 Mbps must meet the following specifications to carry 1300 nm wavelength for the specified distance:

∙Multi-mode cable ISO/IEC 793-2 type B1 and ITU-T G.652 standards

∙Cable must have SC connectors

Fiber optic cables attached to the gigabit expansion module must meet the following specifications to carry 850 nm wavelength for the specified distance:

∙Multi-mode cable ISO/IEC 793-2 type B1 and ITU-T G.652 standards

∙Cable must have SC connectors

Gigabit traffic can travel the following distances using the specified cable:

∙62.5 um cable 720 feet (220 meters)

∙50 um cables 1639 feet (500 meters)
