1x3 Raman WDM
OE Photonics' Raman WDM uses dielectric thin-film filtering to increase capacity by transmitting multiple channels at distinct wavelengths over 1260nm-1620nm on one fiber. A receiver-side demultiplexer separates wavelengths for different equipment. The range meets ITU-I G.695 and is widely used in fiber-sensing systems.
