1000BASE-T SFP Transceiver Modules
The 1000BASE-T SFP transceiver modules provide Category 5, Category 5e, and Category 6 support for
SFP modules. The 1000BASE-T SFP transceiver modules use standard four twisted-pair cable at lengths
up to 328 feet (100 meters) and have standard RJ-45 connectors.
Figure 1-11 shows a 1000BASE-T SFP
module.

CWDM SFP Optical Transceiver Modules
The Coarse Wavelength Division Multiplexing (CWDM) SFP optical transceiver modules are
hot-swappable, and can be plugged into standard receptacles in switching modules that convert Gigabit
Ethernet electrical signals into a single-mode fiber-optic (SMF) interface. You can connect the CWDM
SFPs to CWDM passive optical system optical add/drop multiplexer (OADM) modules or
multiplexer/demultiplexer plug-in modules using single-mode fiber-optic cables with standard SC
connectors.
Table 1-6 lists the available CWDM SFP wavelengths and color-coding identifier.

1. A mode-conditioning patch cord is required. Using an ordinary patch cord with MMF, 1000BASE-LX/LH SFP modules, and
a short link distance can cause transceiver saturation, resulting in an elevated bit error rate (BER). When using the LX/LH
SFP module with 62.5-micron diameter MMF, you must also install a mode-conditioning patch cord between the SFP module
and the MMF cable on both the sending and receiving ends of the link. The mode-conditioning patch cord is required for link
distances greater than 984 feet (300 m).

2. 1000BASE-ZX SFP modules can reach up to 100 km by using dispersion-shifted SMF or low-attenuation SMF; the distance
depends on the fiber quality, the number of splices, and the connectors.
