Table 1 lists the specifications for
links using 9/125-μm fiber cable. The trunk cable to which the
IBM® jumper cables are connected must have
optical properties that conform to the specifications in the table.

Notes:
- The maximum link length includes both jumper cables and trunk
cables.
- Single Mode connectors and splices must meet a minimum return
loss specification of 12 dB.
- In a single mode jumper cable, the minimum distance between the connectors or splices is 2 meters (6.56 feet).
- In a single mode trunk cable, the distance between the connectors
or splices must be sufficient to ensure that only the lowest-order
bound mode propagates.
