Return path receiver with DOCSIS 3.0 performance from Alloptic

Alloptic has made available a new EVRRL410 series of Return Path Receivers offering DOCSIS 3.0 performance with the wide dynamic range to operate a high capacity QAM return path using a RFoG architecture.

The Return Path Receiver builds upon the Alloptic's Receiver line, and provides 7 dB noise performance improvement over typical analog return receivers and almost 3 dB improvement over other Alloptic receivers. This low noise performance translates into the ability to carry, with 15dB of margin, 4 bonded 64QAM channels in a DOCSIS 3.0 return path over an SCTE-standard, RFoG architecture operating with a 29dB optical budget.

"Alloptic is proud to be extending our leadership in the RFoG market. We are committed to using standards-based solutions to resolve application issues," says Shane Eleniak, Executive Vice President of Marketing and Business Development at Alloptic. "The new ultra low noise Return Path Receivers provide significant margin, allowing greater than 20km optical reach and more splits per PON, simplifying the successful deployment of DOCSIS 3.0."

"Other vendors have proposed proprietary methods for reach and density, but from a deployment and purchasing perspective it just makes more sense to choose a standards-based approach that offers interoperability and more flexibility. Alloptic delivers dynamic range and noise performance better than or equal to the best proprietary schemes, but with a fully compatible, non-proprietary solution."

The Return Path Receiver product line includes designs for both typical and high RF output requirements, ones used for long reach and fiber-starved deployments. All receivers are temperature-hardened in 1RU form factors, with both front and rear access versions.

RFoG leverage HFC equipment and back-office applications with the new FTTP deployments. Cable operators can continue to rely on the existing provisioning and billing systems, CMTS platforms, headend equipment, set-top boxes, conditional access technology, and cable modems while gaining benefits inherent with RFoG and FTTx.
