CWDM
Cost-effective, high-density RF over Fibre solutions
ETL’s StingRay CWDM range of RF over Fibre products has been designed for high density & distances of up to 50km.
CWDM stands for Coarse Wavelength Division Multiplexing and is a cost-effective solution for transmitting multiple wavelengths on a single optical fibre link (< 35 km), without optical amplification. There are 16 optical channels altogether.

CWDM vs DWDM: What’s the difference?
Satellite ground stations traditionally use coaxial cables to transmit RF signals, but these suffer from high transmission losses and signal degradation over long distances. As a result, RF over Fibre, using CWDM or DWDM, is becoming essential for efficient, long-distance transmission. This article clarifies the differences between CWDM and DWDM and addresses their respective challenges. Read more.
FAQs
CWDM (Coarse Wavelength Division Multiplexing) enables the transmission of multiple RF signals on different wavelengths over a single fibre, making it a cost-effective solution for applications requiring moderate transmission distances (up to 50km) without the need for optical amplification.
ETL Systems’ StingRay CWDM RF over Fibre solutions can transmit signals over distances of up to 50km, making them ideal for medium-range applications without the need for optical amplification.
The StingRay CWDM system supports up to 16 optical channels, providing flexibility and efficiency for transmitting multiple signals over a single fibre.
CWDM is a low-cost solution that provides high-density signal transmission over moderate distances. It is more affordable than DWDM, making it suitable for applications where shorter transmission distances and fewer channels are needed, without the need for costly optical amplification.
ETL’s StingRay CWDM RF over Fibre solutions are commonly used in applications such as satellite ground stations, teleports, and broadcast facilities where moderate distance transmission and high-density RF signal transport are required.
