HP Mainframe Connectivity Design Guide

Table 42 (page 79) describes the distance rules for 4 Gb/s FICON connections when using 4
Gb/s FICON director models.

Information for 62.5 µm fiber optic cable is provided to facilitate use of installed cable. HP recommends 50 µm fiber optic cable
for new installations that require multi-mode fiber.
2
WDM distance is the maximum distance for the WDM link with FICON. Not all WDM products are certified for this distance.
Depending on the application, an IBM request for price quotation may be required for any distance over 100 km. For GDPS
applications, contact IBM for WDM products that support GDPS.

HP P9000/XP Continuous Access software uses FCP (not FICON). For B-series directors, these distances are supported with firmware
4.4x or later.
