Installing the Modules
mini-GBIC XL Module
fiber-optic
cable with
LC connector
Notes:
Gigabit-LX – If multimode cable is used, a mode conditioning patch cord may be needed — see "Mode Conditioning
Patch Cord" on page 24 for more information.
Gigabit-LH – Between the transmit and receive ends of the cable, at least 5dB of attenuation is required for a reliable
connection. This is equivalent to 20Km of the fiber-optic cable. For distances less than 20Km, you must add attenuators
to bring the total attenuation to at least 5dB. Most cable vendors carry attenuators.
