Product Code : SNT-FWDM-1*2-0.9MM-SCA

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.
