Cables
For 25 GbE, IBM
transceivers are included on each end of these cables.

Transceivers
For 25 GbE, IBM
adapter. Customers can also use their own optical cabling and SFP28 optical transceiver for the other
end. The 25 Gb optical transceiver is capable up to 100 m through the OM4 cable or 70 M through
OM3 cable. Either one or both of the adapter's two SFP28 ports can be populated.
For 10 GbE, IBM
Customers can also use their own optical cabling and SFP+ optical transceiver for the other end. The
10 Gb optical transceiver is capable up to 300 M through the OM3 cable or 82 m through OM2 cable.
Either one or both of the adapter's two SFP28 ports can be populated.
Cable and Transceiver information
Use multimode fiber optic cables with shortwave lasers that adhere to the following specifications:
• OM3 or OM4: Multimode 50/125 micron fiber, 2000 MHz x km bandwidth
• OM2: Multimode 50/125 micron fiber, 500 MHz x km bandwidth
• OM1: Multimode 62.5/125 micron fiber, 200 MHz x km bandwidth
Because core sizes are different, OM1 cables can only be connected to other OM1 cables. For best
results, OM2 cables must not be connected to OM3 or OM4 cables. However, if an OM2 cable is
connected to an OM3 or OM4 cable, the characteristics of the OM2 cable apply to the entire length of the
