Mini-GBIC vl Module
Gigabit-SX operation:
multimode fiber-optic
cables fitted with LC
connectors
220 meters to 550 meters,
depending on the cable
used. See “Fiber-Optic
Cables” on page 29 for
more information.
Gigabit-LX operation:
single-mode fiber-
optic cables fitted with
LC connectors.
multimode fiber-optic
cables may also be
used—see “Fiber-
Optic Cables” on page
29.
• single-mode cable: 10
kilometers
• multimode cable: 550
meters
Gigabit-LH operation:
the same single-mode
fiber-optic cables used
for Gigabit-LX.
70 kilometers
1000Base-T operation:
four pair category 5
(category 5e or greater
is recommended), 100-
ohm, balanced
twisted-pair cable.
100 meters
Notes: Gigabit-LX – If multimode cable is used, a mode conditioning patch cord may be needed — see “Mode
Conditioning Patch Cord” on page 34 for more information.
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.

operation:
62.5 μm cable
50 μm cable
160 Mhz*km = 2-26 meters
200 Mhz*km = 2-33 meters
400 Mhz*km = 2-66 meters
500 Mhz*km = 2-82 meters
2000 Mhz*km = 2-300
meters
LR operation:
single-mode cable 2 meters - 10 km
ER operation:
single-mode cable
2 meters - 30 km - (40 km
supported on engineered
links
