Product Overview

The QAMnet qEDFA series of Erbium Doped Fiber Amplifiers (EDFA) are reliable fiber amplifiers with high output for use in HFC, FTTH, PON and deep-fiber applications. Utilizing high power pump laser modules, the qEDFA amplifiers deliver optical output levels up to +37 dBm (5,000 mW). This combination of technologies provide the highest mW per dollar ratio.

Depending on the number of pump lasers modules and configuration, qEDFA amplifiers produce optical output level from +25 dBm up to +37 dBm. The high power booster qEDFA is housed in a standard 19” 2RU rackmount unit.

Applications
