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 two kilometers (1.25 miles) in full duplex and 412 meters (1350 feet) 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:
∙
∙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:
∙
∙Cable must have SC connectors
Gigabit traffic can travel the following distances using the specified cable:
∙62.5 um cable 220 meters (720 feet)
∙50 um cables 500 meters (1639 feet)
