Polarization Maintaining Fused WDM
(488/532, 488/633, 532/633, 532/780, 633/780, 633/840nm)
GEZHI Photonics' fused polarization maintaining (PM) wavelength division multiplexer (WDM) can multiplex two wavelengths in a polarization maintaining fiber while maintaining the polarization of the incident light. They are bidirectional; Two discrete wavelengths entering the same port can be divided into two separate optical fiber outputs. They are not suitable for separating the output light from broadband light sources. PM WDM is commonly used in pump/signal applications that integrate erbium or ytterbium doped fiber amplifiers. They can be customized for various applications to accelerate the design cycle and implementation of new projects.
The existing wavelength of Polarization maintaining PM Fused WDM is:
488/532nm PM WDM, 488/633nm PM WDM, 532/633nm PM WDM, 532/780nm PM WDM, 633/780nm PM WDM, 633/840nm PM WDM, 980/1030nm PM WDM, 980/1064nm PM WDM, 980/1310nm PM WDM, 980/1550nm PM WDM, 1064/1550nm PM WDM, 1310/1550nm PM WDM, 980/2000nm PM, 1570/2000nm Polarization maintaining PM Fused WDM.

Note:
1.Above specifications are for device without connector, If with connector, IL will be 0.3dB higher, return loss with be reduce 5dB and Extinction Ratio will reduce 2dB.
2. The PM fused WDM is both axis working, no axis can be blocked.
