This CWDM 8 skip 0 band filter is 3 ports passvie optical component based on TFF (Thin Film Filter) technology, which can split 8 CWDM wavelengths 1470-1610nm or 1471-1611nm from input mixed optical signals 1260-1620nm to PASS port, and other 10 CWDM wavelengths 1270-1450nm or 1271-1451nm go to REFLECT port. It can reduce the insertion loss by using it to reduce the cascade.
