980/1550nm WDM-Isolator Hybrid Combination
This 1x2 WDM and isolator hybrid device (1x2 IWDM) 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.
