Mini Size PM WDM (Wavelength Division Multiplexer)
Miniature Polarization-Maintaining Wavelength Division Multiplexer (PM WDM) designed for compact DWDM modules, CATV links, and fiber amplifier optical sub-assemblies. Combines or separates pump and signal wavelengths with high isolation (up to 30 dB), low insertion loss (<=0.7 dB), and compact dia. 3.2 x 30 mm footprint.
Technical Specifications
With connectors, IL increases by 0.3 dB, RL decreases by 5 dB and ER decreases by 2 dB. Custom transmission/reflection bands and connector terminations are available upon engineering review.
Configuration and ordering notes
The wavelength pair defines the signal and pump channels. Port mapping, fiber type and package are reviewed for the selected WDM configuration.
Key Applications
Miniature EDFA & YDFA amplifiers; Compact DWDM systems & transceivers; Fiber sensing pump-signal multiplexing; CATV links & optical line cards.
