PWDM
PWDM is used for packaging of optical module. It can realize the multiplexing of two communication signal, which expands the capacity of single fiber and achieves bi-directional communication. It is widely used in optical network upgrade and expansion, or introduce new comprehensive business (CATV, TELECOM, integration of three networks-PON+EOC) etc.

1x3 Raman WDM
Wavelength-Division Multiplexing (WDM)
Oe-photonics
Wavelength Range: 1450/1550/1660 Insertion Loss: ≤1.4 dB Polarization Dependent Loss: ≤0.2 dB
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.
