Small form-factor pluggable transceiver modules
The FC ports on the 8-Gb/s FC I/O module support 2-, 4-, and 8-Gb/s Fibre Channels and
on the 16-Gb/s FC I/O module supports 4, 8, and 16-Gb/s Fibre Channels using a small
form-factor pluggable plus (SFP+) transceiver module. The SFP+ transceiver modules
connect to Lucent Connector (LC) type interface (see
“Lucent Connector type interface”
this page for more information) optical fibre cables. These SFP+ transceiver modules are
input/output (I/O) devices. These SFP+ modules are hot swappable. This means that you
can install and remove an SFP+ module while the SP is operating.
shows an example of an SFP+ module.
Note: Besides the FC I/O modules, the FCoE and the 10-Gb/s Optical I/O modules also use
SFP modules. Each of these I/O modules use a different type of SFP. Refer to the Parts
Location Guide for more information.

Lucent Connector type interface
The Lucent Connector (LC) type interface was developed by Lucent Technologies (hence,
Lucent Connector). It uses a push-pull mechanism. LC connectors are normally held
together in a multimode duplex configuration with a plastic clip. These cables are usually
colored orange for OM2 multimode optical fiber type cables and aqua for OM3 multimode
optical fiber type cables. These cables have the duplex connectors encased in a gray
plastic covering. To determine the send or transmit (TX) and receive (RX) ferrules
