QSFP+ breakout cable specifications
This section provides a list of the supported breakout cables (BOC).
QSFP+ to 4xSFP+ 10 Gigabit BOC
The QSFP+ to 4xSFP+ 10 Gigabit BOC assembly directly connects one QSFP+ port to four SFP+
ports.
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 breakout cable (BOC) assembly.
In the following figures, the total cable length for all BOCs spans from the nose of the QSFP+
connector to the nose of the SFP+ connector.
Active optical BOCs—The length from the nose of the QSFP+ connector to the optical splitter is
approximately 8 meters. The length of each optical pigtail is approximately 2 meters. The total cable
length is 10 meters.

Passive copper BOCs—The length from the nose of the QSFP+ connector to the fanout of the four
copper pigtails is 10.2 cm. The total cable length can be 1, 3, or 5 meters.

The following tables provide a list of active and passive BOCs, and includes the part numbers and
minimum software version supported.
