Notes: Gigabit-LX – If multimode cable is used, a mode conditioning patch cord may be needed — see "Mode
Conditioning Patch Cord" on
Gigabit-LH – 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.
