XENPAK Technical Specifications
Table 23 lists specifications for the SR 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 24 lists specifications for the LR XENPAK module.
