Thin Film
Filter Based WDM

Thin Film Filter based WDM are extensively used in EDFA, Raman amplifiers, WDM networks and fiber optics instrumentation. This device combines or separates optical signal at different wavelengths in numerous wavelength ranges. It expands the capacity of a single fiber to achieve bidirectional communication and is perfect for optical network upgrade and expansion.

With state-of-the-art manufacturing processes, Crowntech offers Thin Film Filter based WDMs that can be customized to the particular wavelength bands for any specified applications achieving low insertion loss, high channel isolation, and excellent environmental stability.

Features:

  • Low Insertion Loss

  • Low PDL

  • Epoxy Free in Optical Path
