Multimode Filter Wavelength Division Multiplexer (WDM) using Thin Film Filters technology couples and emits light sources at different wavelength into an optical fiber. It provides very low insertion loss, high isolation and excellent environmental stability. In addition, because it is used high quality AR coating and unique pigtail processing which can be provided high power handling capability. Therefore, this device can be used in multi-mode fiber communication, CATV and testing instrumentation.
