Cables
®
For 10 GbE, IBM
offers Direct Attach Copper (DAC) cables up to 5 M. SFP based transceivers are
included on each end of these cables. For more information about adapter cabling, see the "Cable and
Transceiver information" on page 41.
Transceivers
®
IBM
qualifies and supports SFP+ optical transceiver (FC EB46) to install into the adapter. 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 SFP+ 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
cables. The following table shows the supported distances for the different fiber optic cable types at
different link speeds.
