4+3 Channel LGX DWDM Mux/Demux C44–C47 with OTDR, Test Tx/Rx, Upgrade, and Express Ports, LC/APC Connectors

This 4-Channel DWDM Optical Passive Mux/Demux is engineered to maximize the capacity of existing fiber optic networks while minimizing the need for new fiber deployment. Operating with 100GHz channel spacing and supporting ITU channels C44–C47 (1625-1670nm range), this module enables the multiplexing or demultiplexing of four discrete wavelengths over a single-mode fiber. The unit includes OTDR(1625nm-1670nm ),Test TX/RX, Upgrade Port (UPG) and an Express Port (EXP) to ensure seamless scalability and future expansion. The UPG supports additional wavelengths within the 1525–1570nm range (excluding active channels), while the EXP accommodates O-band and L-band wavelengths (1260–1520nm and 1580–1620nm), providing a cost-effective path for network growth. Equipped with LC/APC connectors and built in an industry-standard LGX form factor, this DWDM Mux/Demux delivers reliable performance and easy integration into existing fiber management systems.
