980/1550nm Single Mode Filter WDM
The 980/1550nm Single Mode Filter WDM is a thin film filter-based wavelength division multiplexer designed to combine or separate 980nm and 1550nm optical signals in single mode fiber systems. It features low insertion loss, high channel isolation, low polarization dependent loss, and stable optical performance in a compact package. This Filter WDM is commonly used in EDFA systems, fiber optic amplifiers, fiber lasers, fiber sensing systems, and optical communication applications where reliable 980nm pump and 1550nm signal wavelength management is required. Pass and reflect channel configurations can be selected according to the system design.
