850/905nm Single Mode Filter WDM
The 850/905nm Single Mode Filter WDM is a thin film filter-based wavelength division multiplexer designed to combine or separate 850nm and 905nm optical signals in single mode fiber systems. It provides low insertion loss, high channel isolation, low polarization dependent loss, and stable optical performance in a compact package. This Filter WDM is suitable for fiber laser systems, optical sensing, test equipment, and short-wavelength optical applications requiring reliable wavelength combining or splitting between 850nm and 905nm channels. Pass and reflect channel configurations can be selected according to the system requirement.
