Cables
For 100G, IBM
®
offers either Direct Attach Copper (DAC) cables up to 2 M or Active Optical Cables
(AOC) up to 100 M. QSFP28 based transceivers are included on each end of these cables. For more
information about adapter cabling, see the “Cable and Transceiver Matrix” on page 98.
Note: For 40G, IBM
®
offers DAC cables up to 5 M. QSFP+ base transceivers are included on each end
of these cables. See FC EB2B, EB2H, and ECBN for a 1 M, 3 M, and 5 M copper cables.
Transceivers
IBM qualies 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 lled, both can have copper cables or optical cables. Additionally, one of the
cables can be copper and the other can be optical. IBM
®
also offers QSFP+ optical transceiver (FC
EB27) to install into the adapter and allowing the customer to use their own optical cabling and
QSP28 optical transceiver for the other end.
