Lucent Connector type interface
46 EMC VNX8000 Hardware Information Guide
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 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.
Figure 33 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.

Figure 33 Example of an SFP+ module
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
(connector ends), these cables will show a letter and numeral (for example A1 and A2 for
the TX and RX, respectively) or a white and yellow rubber gasket (jacket) for the send or
transmit (TX) and receive (RX) ends
