4-Channel BiDi O-Band DWDM MUX/DEMUX, Single Fiber, Low O-Band, LGX – A/B Side
The GLOBALfiber 4-Channel BiDi O-Band DWDM MUX/DEMUX is a fully passive single-fiber bidirectional DWDM solution designed for efficient point-to-point transmission in the O-Band (low band).
The unit supports 4 DWDM channels per direction (8 wavelengths total), enabling simultaneous transmit and receive over a single optical fiber using matched A-Side and B-Side modules.
This compact LGX module is ideal for fiber-constrained environments and applications such as access aggregation, short-reach DWDM links, data centers, broadcast & TV, cloud infrastructure, finance, and government networks.
