• 50 µm cable:
– 400 MHz*km = 500 meters
– 500 MHz*km = 550 meters
Gigabit-LX 9/125 μm (core/cladding) diameter, graded index,
low metal content, single mode fiber-optic
cables, complying with the ITU-T G.652 and ISO/
IEC 793-2 Type B1 standards.
OR
the multimode fiber-optic cables listed for
Gigabit-SX.
LC • single-mode cable: 10 kilometers
• multimode cable: 550 meters
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 43 for more information.
Gigabit-LH 9/125 μm (core/cladding) diameter, graded index,
low metal content, single mode fiber-optic
cables, complying with the ITU-T G.652 and ISO/
IEC 793-2 Type B1 standards.
LC 70 kilometers
Note: The transmission distances are dependent on the particular fiber loss and coupling loss involved,
among other factors, and can be estimated from the optical loss budget. For distances less than 20km,
a 10dB attenuator must be used. For distances between 20km and 40km, a 5dB attenuator must be used.
Attenuators can be purchased from most cable vendors.
