For supported distances, see Table 64 (page 156), Table 65 (page 156), and Table 68 (page
158).
Fibre Channel
Note: For Synchronous replication, distance impacts performance. HP recommends a maximum
distance of 200 km when using dark fiber.
HP P9000 (XP) Continuous Access is supported with all WDM products supported by the
switch vendors. See “Certified third-party WDM products” (page 317).
