FWDM Splitter With High Stability
Modulelink FWDM filter 1310 1550 optical splitter and FWDM T1550 R1310&1490 can achieve 1550/1310&1490 two channel optical signal multiplexing and demultiplexing, genaratiing single optical fiber transmission capacity multiplier, Widely used in optical fiber network upgrading and CATV network etc.
FWDM Splitter 1310/1490/1550nm 80km
Modulelink FTTX Filter WDM module is design and manufactured based on Thin Film Filter (TFF) technology. The device combines or separates light at different wavelengths in a wide wavelength range. They can be working well with very low insertion loss, low polarization dependence, high isolation and excellent environmental stability. Modulelink FTTH/FTTX 1310/1550nm FWDM Filter WDM can differ the multiplexing and de-multiplexing of communication optical signals of 1310nm and 1550nm. It can expand the capacity of a single fiber to achieve bidirectional transition, so it is widely used in optical network upgrade and expansion, or introduce new comprehensive business etc. GEPON system itself works on 1310/1490, so CATV signal here is delivered over same fiber using 1550nm, and FWDM is a place where all this gets "mixed".
