Chapter 5: Small form factor pluggable plus
transceivers
This section describes how to select and install small form factor pluggable plus (SFP+)
transceivers.
Use an SFP+ transceiver to connect a device motherboard to fiber optic or direct attached cables.
SFP+ transceivers are similar to SFP transceivers in physical appearance but SFP+ transceivers
support 10 gigabit per second (Gb/s) connections. You must ensure that your switch supports SFP+
transceivers before installation or use. SFP+ transceivers and XFP transceivers both support 10
Gb/s connections, but are not compatible devices. SFP+ transceivers are physically smaller than
XFP transceivers.
Important:
Avaya recommends that you only use Avaya qualified transceivers. If you use other vendor
transceivers, Avaya does not support them.
Selecting an SFP+
About this task
Use an SFP+ transceiver to interface a device motherboard to a fiber optic cable. Select the
appropriate transceiver to provide the required reach.
Procedure
1. Determine the required reach.
Depending on the product, you can obtain SFP+s for cable distances of up to 15 meters (m),
300 m, 10 kilometers (km), and 40 km.
2. Determine wavelength restrictions or requirements.
3. Use the following job aid to determine the appropriate SFP+ for your application.
