Connector and Cable Specifications
Cables and Adapters
SFP Module Cables
Each port must match the wave-length specifications on each end of the cable, and for reliable communications, the
cable must not exceed the allowable length. Copper 1000BASE-T SFP transceivers use standard four twisted-pair, CAT5
(or greater) cable at lengths up to 328 feet (100 meters).
Notes
The maximum operating temperature of the switch varies depending on SFP module type. See
for information on the supported temperature ranges.
Modal bandwidth applies only to multimode fiber (MMF).
A mode-field diameter/cladding diameter = 9 micrometers/125 micrometers.
1000BASE-LX/LH SFP modules connected with MMF over a short link distance require a mode-conditioning patch
cord.
Ordinary patch cords can cause transceiver saturation, resulting in an elevated bit error rate (BER). Using the
1000BASE-LX/LH SFP module with 62.5-micron diameter multimode fiber (MMF) requires a mode-conditioning
patch cord between the single mode fiber (SMF) SFP module and the MMF cable on both the send and receive link
ends.
Link distances greater than 984 feet (300 m) require a mode-conditioning patch cord.
1000BASE-ZX SFP modules can send data up to 62 miles (100 km) by using dispersion-shifted SMF or
low-attenuation SMF. The distance depends on fiber quality, the number of splices, and the connectors.
When the fiber-optic cable span is less than 15.43 miles (25 km), insert a 5-decibel (dB) or 10-dB inline optical
attenuator between the fiber-optic cable plant and the receiving port on the 1000BASE-ZX SFP module.
