1x3 Raman Filter WDM for DTS Systems (1450/1550/1650nm )

The Raman Wavelength Division Multiplexer (Raman WDM) 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). Raman Filter WDM Designed by Idealphotonics,inc Vancouver Branch with low insertion loss and high isolation Characteristic. It's widely used in Raman DTS systems or other fiber test or measurement systems.
