Wuxi Orient Rising Sun Telecom System Equipment Co.,LTD

Model Number: OP-FWDM-T31/R4955 Brand Name: OPTOSTAR Key Specifications/Special Features: FTTH/FTTx Pass 1310nm Reflect 1490nm & 1550nm FWDM Filter WDMDescription:FTTX filter WDM module extensively used in EDFA, Raman amplifiers, WDM networks and fiber optics instruments is based on thin film filter(TFF) technology. The device combines or separates light at different wavelengths in a wide wavelength range. It can expand the capacity of a single fiber to achieve bidirectional communications, so that widely used in optical network upgrade and expansion, or introduce new comprehensive business etc.OPTOSTAR provides filter-based wavelength division multiplexing(WDM) filter devices that are customized to the particular wavelength bands for your special applications. As you might know, GEPON system itself works on 1310/1490nm, so CATV signal here is delivered over same fiber using 1550nm, and FWDM is a place where all this get "mixed".
