Description
1x3 Raman Filter WDM for DTS Systems
The Raman Wavelength Division Multiplexer Module is manufactured with thin-film-filter technology, featuring low insertion loss and high isolation characteristic. It’s widely used in Raman DTS systems or other fiber test or measurement systems.
Arkoptics 1×3 Raman WDM separates and combines different signal wavelengths of 1450nm, 1550nm, and 1660nm (or 1650nm), thereby transmitting multiple wavelengths on one optical fiber to increase the network capacity. Both Single Mode and Multimode Raman WDMs are available.
