Model Number: OP-FWDM-T55/R3149-#7130 Brand Name: OPTOSTAR Key Specifications/Special Features: Description:FTTH/FTTx pass 1550nm reflect 1310nm&1490nm FWDM filter WDMFTTx Filter WDM Module extensively used in EDFA, Raman amplifiers, WDM networks and fiber optics instrumentation is based on thin film filter (TFF) technology. The device combines or separates light at different wavelength range. It can expand the capacity of a single fiber to achieve bidirectional communication, 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".Item details:Pass (transmission) channel: 1550nmReflection channel: 1310nm and 1490nmHigh isolation, reliability and channel isolation
Low insertion loss and excellent environmental reliability
RoHS compliant
Package type
Steel tube package for 250um bare fiber and 900um fiber
ABS box for 900um, 2.0mm and 3.0mm fiber
Note: 250um bare fiber is too fine to be equipped with connector
