SFP+ Transceiver Specifications
The IBM SAN c-type Directors are compatible with SFP+ transceivers and cables that have LC connectors.
The wavelength of each transceiver must match the transceiver on the other end of the cable, and the
cable must not exceed the stipulated cable length for reliable communications.
SFP+ transceivers provide the uplink interfaces, laser transmit (Tx) and laser receive (Rx), and support
850 to 1610 nm nominal wavelengths, depending upon the transceiver.
Use only Cisco SFP+ transceivers on the SAN c-type Directors. Each SFP+ transceiver is encoded with
model information that enables the switch to verify that the SFP+ transceiver meets the requirements for
the switch.
