Applications
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.
or
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.

ETL’s L-Band RF over Fibre link (850-2450 MHz) is designed to cover extensive distances, providing robust signal transmission up to 10 km or up to 50 km when utilising Coarse Wavelength Division Multiplexing (CWDM) technology. For even greater distances, ETL offers a Long-Distance Dense Wavelength Division Multiplexing (DWDM) system capable of reaching up to 500 km. This advanced fibre link solution ensures high-quality, long-range signal distribution. It is ideal for a wide range of satellite communication applications that require reliable and efficient RF signal routing over substantial distances.
1U or 2U Module Sizes
ETL Systems’ GENUS StingRay RF over Fibre modules offer versatile solutions in either 1U or 2U configurations, accommodating diverse deployment needs. These modules support a wide spectrum of frequency bands, including the C-Band links spanning from 500MHz to 6.7 GHz. Designed to enhance signal transmission efficiency, the GENUS StingRay modules are pivotal in critical communication infrastructures where reliability and performance are paramount. Whether used in satellite ground stations, broadcast facilities, or military applications, these RF over Fibre solutions provide robust connectivity solutions that meet the demanding requirements of modern telecommunications and broadcast industries.
Hot Swappable Modules
Hot swappable modules offer significant benefits in ground segment systems by enabling the replacement or upgrade of hardware components without interrupting service or powering down equipment.
This feature is crucial for maintaining continuous operation, particularly in mission-critical environments such as satellite communication, where downtime can lead to data loss or disruption of services. Hot swappability ensures swift and efficient maintenance, reducing repair times and operational costs while enhancing system reliability and uptime. Additionally, it allows for easy scalability and flexibility, enabling ground stations to adapt quickly to changing technology and capacity requirements.
Secure protocols with SNMPv3 and HTTPS
Implementing secure protocols like SNMPv3 and HTTPS in network management provides substantial benefits by ensuring the safety and integrity of data communications. SNMPv3 (Simple Network Management Protocol version 3) enhances security through robust authentication and encryption mechanisms, protecting network devices from unauthorised access and tampering. It also supports fine-grained access control, allowing administrators to precisely manage user permissions.
Meanwhile, HTTPS (Hypertext Transfer Protocol Secure) encrypts data transmitted over the internet, safeguarding sensitive information from interception and attacks during remote access and control of network devices. Together, these protocols help protect critical infrastructure from cyber threats, enhance compliance with security standards, and foster trust in network management practices. By securing both local and remote communication channels, they provide a resilient foundation for reliable and secure operations in modern networking environments.
Local & Remote control & monitoring
Local and remote control and monitoring capabilities provide essential advantages in managing complex systems and networks. Locally, operators can directly oversee equipment status, troubleshoot issues promptly, and make real-time adjustments to optimise performance. This immediate access is critical for maintaining operational continuity and responding swiftly to changing conditions or emergencies.
On the other hand, remote control and monitoring extend these capabilities beyond physical proximity, allowing administrators to manage devices and systems from virtually anywhere. This flexibility enhances operational efficiency by reducing the need for on-site interventions and enabling proactive maintenance and upgrades. Additionally, remote monitoring provides insights into long-term performance trends, enabling data-driven decision-making and predictive maintenance strategies. Overall, the combination of local and remote control and monitoring empowers organisations to maximise uptime, ensure regulatory compliance, and deliver reliable services to end-users.

FAQs
ETL’s RF Over Fibre modules convert radio frequency (RF) signals into optical signals for transmission over fibre optic cables. This process involves modulating an RF signal onto a light wave using a laser, transmitting it through fibre optic cables, and then demodulating it back to an RF signal at the receiving end. This method enables long-distance transmission with minimal signal loss and interference.
ETL’s RF Over Fibre modules provide several advantages over traditional coaxial cable systems, including:
Extended Range: Fibre optic cables can transmit signals over much longer distances without significant signal loss.
Lower Attenuation: Fibre optics have lower signal attenuation, ensuring better signal quality over long distances.
Immunity to EMI/RFI: Fibre optics are immune to electromagnetic interference (EMI) and radio frequency interference (RFI), making them ideal for environments with high levels of electrical noise.
Reduced Weight and Size: Fibre optic cables are lighter and thinner than coaxial cables, making installation easier and less space-consuming.
ETL’s RF Over Fibre modules are designed to handle a wide range of RF signals, including those used in satellite communications, GPS/GNSS, broadcast, and military applications. They can accommodate frequencies from a few MHz up to several GHz, making them suitable for various applications that require high-fidelity signal transmission over long distances.
