Maximum Length
100Base-FX 62.5/125 μm or 50/125 μm (core/cladding)
diameter, graded-index, low metal content,
multimode fiber-optic cables, complying with the
ITU-T G.651 and ISO/IEC 793-2 Type A1b or A1a
respectively.
MT-RJ or
LC
• full-duplex connections:
2 kilometers
• half-duplex connections:
412 meters
Note: MT-RJ connector is on the module or an LC connector on the SFP transceiver.
Gigabit-SX 62.5/125 μm or 50/125 μm (core/cladding)
diameter, graded-index, low metal content,
multimode fiber-optic cables, complying with the
ITU-T G.651 and ISO/IEC 793-2 Type A1b or A1a
respectively.
LC • 62.5 µm cable:
– 160 MHz*km = 220 meters
– 200 MHz*km = 275 meters
• 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 34 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.
