Product Overview of PM Fused WDM
High stability & Reliability 1x2 Polarization Maintaining Fused WDM
applied Fiber Sensor
Polarization Maintaining Fused WDM
GEZHI uses unique fusing technique and polarization maintaining
fiber to build the polarization maintaining fused WDMThe
Polarization Maintaining Fused WD (Wavelength Division
Multiplexers) combine or separate light at different
wave-engths.They offer very low insertion loss, low polarization
dependence, high isolation, and excellent enviromental
stabilityThese components have been extensively used in EDFA, CATV,
WDM networks and fiber optics instrumentation.
