Note:
To use multimode cables for Gigabit-LX, a
mode conditioning patch cord
may be needed — see
“Mode Conditioning Patch Cord for Gigabit-LX” on page 24 for more information.

LC
70 kilometers
Note:
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.
