Super Mini 980/1550nm WDM-Isolator- Tap Hybrid Combination

The hybrid device of WDM + isolator + beam splitting can be used in EDFA with high isolation requirements, which can not only ensure the optical isolation to meet the requirements, but also reduce the size of the entire EDFA module. The isolator plays the role of reverse isolation here to further ensure that the isolation of the WDM device meets the requirements of EDFA.
