Single Mode link specifications

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.
Table 1. Maximum link loss (at 1300-nanometer wavelength)
Link Type Maximum Link Length in km (Miles) Maximum Link Loss (dB) Trunk Size (μm)
fibre channel 10 7.8 9~10
Notes:
  1. The maximum link length includes both jumper cables and trunk cables.
  2. Single Mode connectors and splices must meet a minimum return loss specification of 12 dB.
  3. In a single mode jumper cable, the minimum distance between the connectors or splices is 2 meters (6.56 feet).
  4. 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.
