Raman WDM Module (1450/1550/1660nm)

  • Wavelength: 1450nm or Custom Wavelength 1660nm 1650nm 1550nm
  • Handling Power: 300mW
  • Fiber Type: Multi-mode Fiber
Product Details

  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). It's featured with low inserion loss and high isolation. It's widely used in raman sensor or other fiber test or meaurement systems.
