CWDM or DWDM – What’s the difference?

CWDM Up to 50 km

ETL’s StingRay CWDM RF over Fibre products are designed for high-density signal transmission over long distances, up to 50 km.

CWDM, or Coarse Wavelength Division Multiplexing, is a cost-effective method for sending multiple wavelengths on a single optical fibre link without the need for optical amplification, typically over distances less than 50 km. The system supports up to 16 optical channels.

DWDM Up to 500 km

ETL’s Stingray DWDM RF over Fibre products boost network capacity by transmitting multiple high-bandwidth signals simultaneously over long distances, up to 500 km.

DWDM, or Dense Wavelength Division Multiplexing, modules enable fibre links to extend up to 500 km and beyond, using optical amplification (EDFA). This technology supports up to forty wavelengths on a single fibre cable, allowing for extremely high-density transmission.
