For combining or separating the 3 wavelengths which are required for a GPON network architecture with RF Overlay (only forward transmission) respectively Active-Ethernet (P2P) with RF Overlay
Usable as MUX (red signal direction) or DEMUX (blue signal direction) due to the bidirectional design
1 Port for 1310 & 1490 nm (GPON), 1 port for 1550 nm (RFoG forward way), 1 COM port
