CWDM SFP |
The Coarse Wavelength Division Multiplexing (CWDM) SFP is a hot-swappable device that you can plug into SFP-compatible modules and supervisor engines. The CWDM SFP transceiver uses an LC optical connector to connect to a single-mode fiber-optic (SMF) cable. You can connect the CWDM SFPs to the CWDM passive optical system optical add/drop multiplexer (OADM) modules or multiplexer/demultiplexer plug-in modules using single-mode fiber-optic cables. |

|
DWDM SFP |
The Cisco DWDM SFP is a hot-swappable I/O transceiver module that you can plug into Gigabit Ethernet SFP ports or slots. It supports the ITU 100-GHz wavelength grid and matches the wavelength plan for the Cisco 100-GHz ONS product family. It is a fixed-wavelength SFP, with 40 different SFP models. It uses standard SFP interface network: dual LC/PC connector.

DWDM SFP+ |
The Cisco DWDM SFP+ transceiver module is a hot-swappable I/O device that you can plug into an Ethernet SFP+ port of a Cisco switch or router to link the port with the network. It supports 40 nontunable ITU 100-GHz wavelengths. It also supports digital optical monitoring capability and the Cisco quality identification (ID) feature, which enables a Cisco switch or router to identify whether or not the module is an SFP+ module certified and tested by Cisco. |

Module Connectors
This section provides brief descriptions of the module connectors that the switch supports.
RJ-45 Connector
The RJ-45 connector is used to connect a Category 3, Category 5, Category 5e, or Category 6 foil twisted-pair or unshielded twisted-pair cable from the external network to the module interface connector.
 Caution | Category 5e, Category 6, and Category 6a cables can store large levels of static electricity because of the dielectric properties of the materials used in their construction. Always ground the cables (especially in new cable runs) to a suitable and safe earth ground before connecting them to the module. |
Caution | To comply with GR-1089 intrabuilding and lightning immunity requirements, you must use a foil twisted-pair (FTP) cable that is properly grounded at both ends. |
SC Connector
The SC connector is used to connect fiber-optic module ports or transceivers with the external SMF or MMF network.
Warning | Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or view directly with optical instruments. Statement 1051 |
Note | Make sure that the optical connectors are clean before making the connections. Contaminated connectors can damage the fiber and cause data errors. |
Always insert the network connector completely into the socket. A secure connection is especially important when you are establishing a connection between a module and a long-distance (1.24 miles) (2 km) network, or a module and a suspected highly attenuated network. If the link LED does not light up, try removing the network cable plug and reinserting it firmly into the module socket. It is possible that dirt or skin oils have accumulated on the plug faceplate (around the optical-fiber openings), generating significant attenuation and reducing the optical power levels below threshold levels so that a link cannot be established.
Caution | Use extreme care when removing or installing connectors so that you do not damage the connector housing or scratch the end-face surface of the fiber. Always install protective covers on unused or disconnected components to prevent contamination. Always clean fiber connectors before installing them. |
LC Connector
The LC fiber optic connector is a small form-factor fiber-optic connector that provides high-density fiber connectivity. The LC connector can be used with either MMF cable or SMF cable. The LC connector uses a latching clip mechanism that is similar to the one used on the RJ-45 copper connector.
Warning | Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or view directly with optical instruments. Statement 1051 |
Note | Make sure that the optical connectors are clean before making the connections. Contaminated connectors can damage the fiber and cause data errors. |
