Fiber Optic Filter WDM Tx 1550nm Rx 1310 / 1490nm CATV Multiplexer
Filter Wavelength Division Multiplexer (FWDM) products is based on environmentally stable Thin Film Filters technology. The device combines or separates light at different wavelengths in a wide wavelength range. It including 1310/1550nm FWDM, 980/1550nm FWDM, 1310/1490/1550/1625nm FWDM etc. Filter Wavelength Division Multiplexer is extensively used in CATV, FTTH,Triple Optical Networks, Fiber Optical Amplifier, Transmitters and Fiber lasers, WDM networks and fiber optics instrumentation.
