The figure below shows the SFP-H10GB-CU5M transceiver. The rubber loop is used for removing the SFP+
from its port on the I/O module.

Optical SFP+ Transceivers
If distances greater than 10 meters (33 feet) must be spanned, the FEX also supports the substitution of the
copper SFP+ by optical SFP+ transceivers. The SFP+ 10-Gb Ethernet optical transceiver is a bidirectional
device with a transmitter and receiver in the same physical package. It has a duplex LC connector on the
optical interface.

While the SFP-10G-LR is supported by both the fabric interconnect and I/O module, the maximum distance will introduce latency issues that will affect overall
performance.
