1000BASE-CWDM SFP Transceiver Cables
The Coarse Wavelength Division Multiplexing (CWDM) SFP transceivers are hot-swappable transceivers that you plug into SFP-compatible I/O modules. The CWDM SFP transceiver uses an LC optical connector to connect to single-mode fiber-optic (SMF) cable. You can connect the CWDM SFPs to CWDM passive optical system optical add/drop multiplexer (OADM) modules or multiplexer/demultiplexer plug-in modules using SMF cables. CWDM SFP transceivers can transmit and receive optical signals up to 61 miles (100 km) depending on the quality of the fiber-optic cable used.
CWDM SFP transceivers are color coded to indicate their designated optical wavelength. Figure B-7 shows the CWDM transceiver, which looks like a standard 1000BASE-X SFP transceiver with a colored arrow and bail clasp to indicate the designated wavelength.

Note Whenever the transceiver receive optical bores are not filled with optical cables, you should minimize the chance of contamination by plugging the transceiver with its dust plug.

RJ-45 Module Connectors
The RJ-45 connector connects Category 3, Category 5, Category 5e, Category 6, or Category 6A foil twisted-pair or unshielded twisted-pair cable from the external network to the following module interface connectors:

Note If you need to connect a host that operates at up to 10 Mbps to a FEX, you can connect the host to a Cisco Nexus 2248TP-E FEX, which has large port buffers that enable it to work at the slower 10-Mbps speed. If the 10-Mbps host that you are connecting cannot autonegotiate speeds, you must configure the host for 10 Mbps when connecting it to the Cisco Nexus 2248TP-E FEX.


Figure B-10 shows the RJ-45 connector.
