XENPAK Technical Specifications

Extreme Networks Pluggable Interface Modules Installation Guide

Table 25 lists specifications for the ER XENPAK module.

NOTE

The launch power (measured using the average power method used by power meters) is measured at the factory. The

average launch power minimum value is provided as a reference, not a pass/fail criterion.

Table 26 lists specifications for the ZR XENPAK module

WARNING!

To prevent permanent damage to the ZR XENPAK and other equipment: always check the optical input power of the

receiver before inserting the fiber. The maximum optical input power for the receiver is -7 dBm. If you use optical

loopback for diagnostics purposes, the loopback requires a minimum of 10 dB optical attenuation. The

recommended attenuation range is 10 dB to 15 dB.
