WDM Components
The Coarse Wavelength Division Multiplexer (CWDM) employs thin-film coating technology and a proprietary non-flux metal-bonded micro-optics packaging design to enable optical add/drop functionality across ITU channel wavelengths from 1270 to 1610 nm. It delivers low insertion loss and wide passbands at each ITU center wavelength, along with high channel isolation. The device features low temperature sensitivity and an epoxy-free optical path, ensuring high reliability and performance for polarization-maintaining systems.

Application context
Application guidance is tied to the configured wavelength, fiber interface and optical-budget fields for this family.
SWDM / CWDM 850-1610nm: Wavelength-division multiplexing depends on preserving the optical budget through the complete path. The 1270 nm, 1290 nm, 1310 nm, 1330 nm wavelength specification sets source and detector compatibility. The fiber/interface entry (SM28, 50/125, PM1310, PM1550, F) must match the connected components.

Technical FAQ
Fiber Type: SM28, 50/125, PM1310, PM1550, F · Fiber Cover: 900 μm tube. Specify connector polish and fiber architecture together. FC/PC, FC/APC and SMA interfaces, and single-mode, multimode and polarization-maintaining fibers, impose different return-loss, mode-field and alignment requirements.
ITU Wavelength: 1270 nm, 1290 nm, 1310 nm, 1330 nm. Check the WDM Components passband, insertion loss, return loss and power handling at the actual source wavelength; a nominal telecom-band label is not a substitute for the configured range.
Share your wavelength, fiber type, connector, power handling and control requirements and we will qualify the matching configuration and part number.
