Transceivers
IBM qualifies and supports QSFP28 optical transceiver (FC EB59) to install into the adapter.
Customers can also use their own optical cabling and QSP28 optical transceiver for the other end.
This is a 100Gbase-SR4 based active optical transceiver capable up to 100 M through the OM4
cable or 70 M through OM3 cable. Either one or both of the adapter's two QSP28 ports can be
populated. When two ports are filled, both can have copper cables or optical cables. Additionally,
one of the cables can be copper and the other can be optical. IBM
