PWDM with blocking XGSPON 1577nm

Pass band 1540-1565nm for CATV
Reflect band 1260-1360 and 1480-1500nm for GPON
Block band 1575-1650nm for XGS-PON and OTDR
Pass port built-in PD photo diode
    This PWDM with blocking XGSPON 1577nm is 3 ports passvie optical component based on TFF (Thin Film Filter) technology, which can divide 1550 CATV signal from GPON XGS-PON and reflect GPON 1310 1490 into another port, block XGS-PON 1577 for pass and reflect port. The pass port built-in PD 3 PINs analog photo diode for receiving CATV signal.
