Table 37 (page 75) lists the 2 Gb/s fiber optic cable loss budgets when using OM1, OM2, or
OM3 multimode fiber optic cable and single-mode fiber optic cable.

Storage product interface and transport distance rules
Table 40 (page 77) through Table 45 (page 81) describe the maximum distances supported for
each cable segment type (director-to-director or device-to-director) for each interface and transport
type. Unless otherwise specified, the distances specified apply to both director-to-director (ISL)
connectivity and device-to-director connectivity.
Table 39 (page 76) describes the distance rules for 16 Gb/s FICON connections when using 16
Gb/s FICON director models.
