Optický konvertor spätného kanála Televes OLR2 TWIN 2xDCSS 2xLegacy

Televes OLR2 TWIN is an optical return converter designed for satellite signal distribution. The unit converts incoming optical signals into electrical satellite outputs, providing two DCSS outputs and two legacy outputs to ensure compatibility with modern DCSS LNBs and older legacy receivers. Intended for centralized fiber-to-coax distribution, the OLR2 TWIN enables shared reception scenarios in residential buildings, multi-dwelling units and commercial installations where both newer and legacy satellite equipment must coexist.

Advantages

The converter supports simultaneous DCSS and legacy outputs, allowing mixed installations without additional signal splitters or separate converters. Optical-to-electrical conversion preserves signal quality over long fiber runs and reduces interference compared with long coax feeds. Compact design and standardized interfaces simplify integration into headends, wiring closets or equipment racks. The presence of two independent DCSS outputs allows distribution to multiple receivers using DCSS technology while maintaining two legacy outputs for direct connection to older receivers.

Suitable for

• Residential multiswitch/headend installations with fiber input
• Multi-dwelling units and apartment buildings requiring mixed DCSS and legacy support
• Commercial installations where centralized distribution and optical links are used
• Upgrades from legacy-only systems to shared DCSS reception without full rewiring

Key specifications

• Input type: optical fiber input designed for satellite signal reception
• Outputs: two DCSS satellite outputs and two legacy satellite outputs
• Conversion: optical-to-electrical satellite signal conversion for coax distribution
• Form factor: compact converter for headend or rack integration
• Compatibility: supports modern DCSS LNBs and legacy receiver equipment

How to use

Connect the optical fiber feed to the optical input following standard fiber handling procedures and then connect coaxial cables from the DCSS and legacy outputs to the respective multiswitches or receivers. Ensure correct optical transmitter power and fiber type are used according to the installation plan. Place the converter in a dry, ventilated environment near the distribution equipment and provide the required DC power and grounding as specified by the system design. Verify signal levels and receiver tuning after installation to confirm correct optical-to-electrical conversion and output allocation.

Recommendations

Use high-quality fiber connectors and maintain proper fiber polarity to avoid signal loss. When deploying in larger systems, document which outputs serve DCSS and which serve legacy receivers to simplify maintenance. Periodically inspect connectors and ensure the converter is protected from extreme temperatures and moisture to maintain stable operation.
