4-Channel O-Band DWDM MUX/DEMUX, Dual Fiber, 200 GHz Spacing, LGX
The GLOBALfiber G-OMUX-4LB-LU is a fully passive O-Band DWDM MUX/DEMUX designed for dual-fiber point-to-point transmission.
It supports 4 DWDM channels with low insertion loss, enabling reliable aggregation of O-Band services where compact form factor and spectral efficiency are required.
With 200 GHz channel spacing in the low O-Band, this solution is well suited for access aggregation, short-reach DWDM links, and environments that benefit from O-Band characteristics such as low chromatic dispersion.
