HP recommends 50 micron fiber optic cable for new installations that require multi-mode fiber. 2Total distance is the sum of all cable segments. 3WDM distance is the maximum distance for the WDM link. 4Up to 240 km at 1 Gb/s, over a WDM link. Certain Fibre Channel switches may have reduced performance at this distance. Table 83 describes the distance rules for ATM extension Fibre Channel connections.
