Description Filter WDM module extensively used in optical amplifiers, WDM networks.
The device combines or separates light at different wavelengths
(1310nm/1490nm/1550nm) 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.It works on 1310nm/1490nm, so CATV signal here is delivered over
same fiber using 1550nm, and FWDM is a place where all this get together. Features
- Wide Wavelength Range
- Low Insertion Loss
- High Channel Isolation
- High stability and
reliability
Applications
- System Monitoring
- Transmitters and Fiber
- Passive Optical Network
(PON)
- Fiber optical amplifier
- CATV System
- FTTH System
