Ideaphotonics 's integrates the functions of 1550 /980 WDM, an optical isolator and a gain flatness filter. This product offers integrated solutions to multistage EDFA applications by combining more functions into a very compact package, it can help to save fiber coiling space, reduce splicing and fiber coiling works while raising up the system reliability and increasing module design efficiency.

Optical Functional Diagram

Application Example 

This is a typical multistage EDFA optical diagram, WIGW offers integrated solutions to this. It reflects the extra pump light into the another EDF for two-stage amplification, meanwhile flatten the gain of signal lights.
