HP Mainframe Connectivity Design Guide

NOTE: Channel insertion loss is the combined passive loss from connectors, splices, and media
between the transmitter and receiver.
A mated connector pair is defined as a device or switch transceiver-to-cable connection, or a
cable-to-cable connection when using a passive coupler in a patch panel. A typical (nonpatch
panel) installation has two mated pairs per cable segment (one for each end of the cable). Additional
mated connector pairs are allowed between two transceivers, provided the total loss of all connectors
and cables does not exceed the total channel insertion loss.
Table 33 (page 73) lists the 16 Gb/s fiber optic cable loss budgets when using OM2, OM3,
OM3+, or OM4 multi-mode fiber optic cable, and single-mode fiber optic cable.
