CWDM Module WDM Co mponents & Module SHIJIA's WDM is based on the thin film filter technology, which can let two or more optical wavelength transmit signals in one optical fiber, or separate the multiplex signals. By cascading 3-ports components, multi-channel module is implemented. Features: • Low Insertion Loss, Low PDL • High Isolation • Epoxy-free optical path • High reliability and stability Applications : • CWDM systems • Access/Metro networks • CATV Networks CWDM Module Specifications: Henan Shijia Photons Technology Co., Ltd.
