Supported QSFP28 transceivers
The following section provides specifications for supported QSFP28 transceivers.
100GBASE-SR4 QSFP28 specifications
The 100GBASE-SR4 transceiver provides a high-speed link at an aggregate signaling rate.
The 100GBASE-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 100GBASE-SR4 QSFP28 transceiver, including test and
measurement information, see the IEEE 802.3-2015 standard.
The following table lists the specifications for the 100GBASE-SR4 QSFP28 transceiver. The part
number of this QSFP28 transceiver is AA1405005-E6.
