40GBASE-SR4 extended reach QSFP+ specifications
The 40GBASE-SR4 4x10GBASE-SR extended reach transceiver provides a high-speed link at an
aggregate signaling rate.
Important:
Not all Extreme Networks networking products support the 4x10GBASE-SR mode of operation.
The 40GBASE-SR4 transceiver supports the MPO connector. Typically, the MPO connector has two
alignment pins, which keeps the connector and the fibers aligned to the mating cable.
For more information about the 40GBASE-SR4 4x10GBASE-SR QSFP+ transceiver, including test
and measurement information, see the IEEE 802.3-2012 standard.
The following table lists the specifications for the 40GBASE-SR4 4x10GBASE-SR QSFP+
transceiver. The part number of this QSFP+ transceiver is AA1404006-E6.
