CATV EDFA Passive Bare fiber T1550nm R1310nm/1490nm FWDM
FTTX 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 wavelengths in a wide 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.
Takfly 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 1310/1490, so CATV signal here is delivered over same fiber using 1550nm, and FWDM is a place where all this get's "mixed".

1. Customization is available.
2. pecified without connector, and add an additional 0.2dB loss per connector.
Reflection Channel: 1310nm and 1550nm
High Isolation, Reliability and channel isolation
Low Insertion loss and excellent environmental reliability
Glass Tube Package for 250um bare fiber
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 finne to be equiped with connector
