Table 77 2 Gb/s fiber optic cable loss budgets (higher bandwidth) Cable Maximum distance per Total channel insertion Maximum loss per cable segment loss mated connector pair 50/125 micron (OM3 2000 MHz-km at 850 nm) 500 m 3.31 dB 0.75 db Table 78 lists the 1 Gb/s fiber optic cable loss budgets when using nominal bandwidth OM1 or OM2 multi-mode fiber optic cable, and single-mode fiber optic cable. Table 78 1 Gb/s fiber optic cable loss budgets (nominal bandwidth) Cable Maximum distance per Total channel insertion Maximum loss per cable segment loss mated connector pair 50/125 micron (OM2 500 MHz-km at 850 nm) 62.5/125 micron (OM1 200 MHz-km at 850 nm) 9/125 micron (singlemode) 500 m 200 m 10 km 35 km 100 km 3.85 dB 3.0 dB 7.8 dB 21.5 dB 19 dB 0.75 dB Storage product interface and transport distance rules Table 79 through Table 82 and Table 85 and Table 86 describe the maximum distances supported for each cable segment type (switch-to-switch or device-to-switch) for each interface and transport type. Unless otherwise specified, the distances specified apply to both switch-to-switch (ISL) connectivity and device-to-switch connectivity. See the HP Continuous Access EVA documentation for interconnect and distance rules for those products. SAN Design Reference Guide 171
