Note: To use multimode cables for Gigabit-LX, a mode conditioning patch cord may be needed - See the
Installation Guide that came with your module for more information.
Gigabit-LH 9/125 mm (core/cladding) diameter, graded-

ITU-T G.652 and ISO/IEC 793-2 Type B1
standards. LC - Gigabit-LH

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.
