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.
Feature:
Wide Wavelength Range
Low Insertion Loss
High Channel Isolation
High stability and reliability
Applications:
System Monitoring
Transmitters and Fiber
Fiber optical amplifier
CATV System
FTTH System
