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.
