SUPPLEMENTAL MATERIAL
Optical SFP+ Transceivers
If distances greater than 5 meters (16.4 feet) must be spanned, the Fabric Extender 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, as shown in
Figure 26
.
It has a duplex LC connector on the optical interface. A fiber optic cable must be used to connect the two
transceivers together.

Fabric Extender Bundles
You can order two kinds of Fabric Extender bundles:
■
UCS-IOM2208-16FET. This bundle includes one 2208XP Fabric Extender plus 16 Fabric Extender
Transceivers (FETs). 8 FETs are used for the Fabric Extender and 8 for the Fabric Interconnect.
■
UCS-IOM2204-8FET. This bundle includes one 2204XP Fabric Extender plus 8 Fabric Extender
Transceivers (FETs). 4 FETs are used for the Fabric Extender and 4 for the Fabric Interconnect.
The FETs are in an SFP+ form-factor and support 10 Gbps full-duplex transmissions between the Fabric
Extender and Fabric Interconnect, using your own multimode fiber (MMF) optical cables. The reach is 25
meters using OM2 MMF optical cables and 100 meters using OM3 MMF optical cables.
If you do not order the bundle that includes the transceivers, you can order the transceivers separately as
spares (PID = FET-10G=).
