| Polarization Maintaining Dense Wavelength Division Multiplexer | |||
| PM Dense WDM | |||
| The polarization maintaining dense wavelength division multiplexer series are designed and manufactured to Telcordial standard and ITU standard, PM DWDM can preserve the polarization of optical signals. The devices use environmentally stable Thin Film Filters and advanced packaging technology to achieve wide passband, low insertion loss, high channel isolation, excellent environmental stability and high extinction ratio. Polarization maintaining dense WDM can be used individually to perform single channel add of drop function or drop function or can be used in DWDM systems and sensor systems. |
