fiber steel tube FWDM module

Share

The Steel tube filter wavelength division multiplexer series are based on environmentally stable thin film filters technology. 

The devices combine or separate light at different wavelength in a wide wavelength range. These components have extensively used in EDFAs, raman amplifier, fiber sensor system, WDM networks and fiber optics instrumentation.
