Manual Fiber Polarization Controllers is made by the principle of birefringence generated by optical fiber under the action of external force. The three rings are equivalent to λ/4, λ/2 and λ/4 wave plates respectively. The light wave passes through the λ/4 wave plate and is converted into linearly polarized light, and then the polarization direction is adjusted by the λ/2 wave plate. The polarization state of the linearly polarized light is changed to an arbitrary polarization state via a λ/4 wave plate. The delay effect caused by the birefringence effect is mainly determined by the cladding radius of the fiber, the radius of the fiber surround and the wavelength of the light wave.
The 1450/1550/1660nm 1x3 Raman Filter WDM for DTS Systems Module is manufactured by using thin-film filter technology, it used to separate and combine different signal wavelengths at 1450nm, 1550nm, and 1660nm (or 1650nm). This 1x3 Raman Filter WDM with low insertion loss and high isolation Characteristic. It's widely used in Raman DTS systems or other fiber test or measurement systems.
The 1X2 1310/1550nm CWDM wavelength WDM Wavelength Division Multiplexer is designed to combine light from two inputs into a single fiber. This WDM is designed for 1310 nm and 1550 nm wavelengths. Like all fused fiber devices, it is bidirectional: it can be used to split two wavelengths from a single input into two outputs. we can also provide other CWDM(1270nm to 1610nm) wavelengths WDM.
