PM Filter WDM (Wavelength Division Multiplexer)
Polarization-Maintaining Filter Wavelength Division Multiplexer (PM FWDM) utilizing thin-film filter technology for reliable optical combining and splitting. Designed for 1064/980nm, 1550/980nm, 1550/1064nm, 1550/1480nm, and 2000/1550nm wavelength multiplexing with low insertion loss (<=0.8 dB) and high isolation (>30 dB).
Technical Specifications
With connectors, IL increases by 0.3 dB, RL decreases by 5 dB and ER decreases by 2 dB. Custom pass/reflection wavelength bands, fiber types, and high power configurations available upon engineering confirmation.
Configuration and ordering notes
Transmission and reflection wavelength bands, fiber type, connector configuration and pigtail length define the WDM configuration.
Key Applications
EDFA and YDFA optical fiber amplifiers; Fiber laser seed & pump combining; Coherent optical telecommunication; Fiber sensing and test systems.
