• Avaya recommends the use of Avaya branded SFP and SFP+ transceivers as they have
been through extensive qualification and testing. Avaya will not be responsible for issues
related to non-Avaya branded SFP and SFP+ transceivers.
Selecting a QSFP+
Use a QSFP+ transceiver to interface a port to a fiber optic cable. Depending on the product, you
can obtain QSFP+ transceivers for cable distances of up to 40 km. Alternatively, you can use a
direct attach cable (QSFP+ to QSFP+ DAC) to connect ports for cable distances of up to 5 meters.
About this task
Select the appropriate transceiver to provide the required reach.
Procedure
1. Determine the required reach.
2. Determine wavelength restrictions or requirements.
3. Use the following job aid to determine the appropriate QSFP+ transceiver or cable for your
application.
Job aid
QSFP+ transceivers are hot-swappable data input and output components that allow 40-gigabit
Ethernet ports to link with other 40-gigabit Ethernet ports.
All Avaya QSFP+ transceivers use LC connectors and MPO/MTP connectors to provide precision
keying and low interface losses.
Note:
The Avaya VSP 4000 does not support 40 Gbps QSFP+ transceivers because the VSP 4000
devices do not have any QSFP+ ports. However, the VSP 4000 series supports the four SFP+
10-gigabit ends of the Direct Attach Breakout Cable (BOC) assembly.
The following table lists and describes the Avaya QSFP+ transceiver models.
