| Multimode Filter Wavelength Division Multiplexer | |
| The multimode filter wavelength division multiplexer series are based on environmentally stable thin film filters technology. The devices combine or separate light at different wavelength in a wide wavelength range. They offer very low insertion loss, high isolation and excellent environmental stability. High power handling capability can be achieved through unique pigtail processing and high quality AR coating. These components have been extensively used in Multi-mode fiber communication ,CATV and testing instrumentation. |
