Thefigure below shows the SFP-H10GB-CU5M transceiver. The rubber loop is used for removing the SFP+
fromits port onthe I/Omodule.

Ifdistances greater than 10 meters (33 feet) must be spanned, the FEX also supports the substitution of the
copperSFP+ by optical SFP+ transceivers. The SFP+ 10-Gb Ethernet optical transceiver is a bidirectional
devicewith a transmitter and receiver in the same physical package. It has a duplex LC connector on the
opticalinterface.
DescriptionModel
Short–rangeoptical SFP+ (up to 300 m/ 984 feet)
SFP-10G-SR
Long–rangeoptical SFP+ (upto 10km/6.2 miles)
SFP-10G-LR4
4Whilethe 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.
