1000BASE-T SFP Modules
Copper 1000BASE-T SFP modules use RJ-45 connectors, as shown in
Figure 6-22
1000BASE-T Copper SFP Module
1000BASE-T copper SFP modules used with the Cisco RFGW-10 UEQAM Supervisor Engine V-10GE
operate only in 1000BASE-T mode, or at 1000 Mbps. Copper 1000BASE-T SFP modules use standard
four twisted-pair, Category 5 cable at lengths up to 328.08 feet (100 meters).
CWDM SFP Modules
You can connect the CWDM SFPs to CWDM passive optical system optical add/drop multiplexer
(OADM) or multiplexer/demultiplexer plug-in modules using single-mode fiber-optic cables with
standard SC connectors. Figure 1-23 shows a CWDM SFP with the optical port dust plug removed.
CWDM SFP Module (Yellow-Coded CWDM-SFP-1550= Shown)
CWDM SFPs come in eight wavelengths that range from 1470 nm to 1610 nm. Color markings on the
devices identify the wavelength to which the Gigabit Ethernet channel is mapped. Table 1-9 lists the
CWDM SFPs with their wavelengths and color codes.
