• Avaya recommends the use of Avaya branded QSFP+ transceivers as they have been
through extensive qualification and testing. Avaya will not be responsible for issues related
to non-Avaya branded QSFP+ transceivers.
Selecting a QSFP+
Use a QSFP+ transceiver for 40 Gigabit per second (Gbps) Ethernet connections over optical fiber.
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+ tranceivers are designed to support 40 Gigabit Ethernet. Different transceiver types are
available for use over different optical fiber types and for different optical reaches.
All Avaya QSFP+ transceivers use LC connectors and MPO/MTP connectors to provide precision
keying and low interface losses.
Installing a QSFP+ transceiver
Install a QSFP+ transceiver to provide a 40 Gigabit Ethernet interface between the device and other
network devices.
Before you begin
• Verify that the QSFP+ is the correct model for your network configuration.
• Before you install the fiber, ensure the connector is clean.
Danger:
Risk of eye injury by laser
