Altera DOCSIS 3.1 Remote PHY Design Enables Distributed Cable Networks
The solution uses Altera Arria® 10 FPGAs and Analog Devices’ class-leading digital-to-analog converters (DACs) and analog-to-digital converters (ADCs), combined with Capacicom’s MAC and PHY implementation, resulting in state-of-the-art radio frequency (RF) performance.
Altera’s distributed CCAP architecture (DCA) solutions support both the legacy DOCSIS 3.0 standard and the new industry standard for cable, DOCSIS 3.1. The latter increases network capacity through the ability to transmit up to 50 percent more data over the same spectrum on existing hybrid fiber-coaxial (HFC) networks, delivering consumer broadband services up to 10 Gbps downstream, and more than 2 Gbps upstream, reducing network delays and improving responsiveness for multi-media applications, such as gaming.
The Altera DCA solution aligns with operator needs to evolve from HFC to DCA in a managed and flexible manner through Altera’s longer term alignment with x86+FPGA platforms, enabling the dynamic segmentation of CCAP as either embedded in the node as an integrated headend or with x86+FPGA as virtualized modules in a datacenter.
“The pent-up demand for new CCAP (converged cable access platform) - capable equipment is evident in the early volume deployments of CCAP gear, and we expect the upward trend in combined CMTS and CCAP channel shipments to continue as operators prepare their networks for DOCSIS 3.1 and remote PHY (physical layer) architectures,” notes Jeff Heynen, IHS Research principal analyst for broadband access and pay TV.
“With today’s Altera FPGA portfolio and onward technology roadmap coupled with Capacicom’s substantial experience in DOCSIS PHY and MAC layers, ADI has now found the perfect combination of partners to extend its leadership in high-performance analog into cable infrastructure solutions,” said Carlton Lane, Analog Devices cable solutions manager. “ADI, Altera and Capacicom have set up a long-term collaboration to create the semiconductor industry reference platform for R - (MAC) PHY, with a continuing roadmap commitment to the lowest power consumption and cost per port.”
“Altera’s DCA solutions help operators meet the demand for higher speed access and increased network efficiency, using the new DOCSIS 3.1 standard, a necessity for cost effectiveness,” said Umar Mughal, Altera director of the broadcast and cable business unit. “Our ongoing technology roadmap will enable us to deliver further, and more dramatic power savings in the node, which for the first time, makes full-spectrum, full unicast 4x4 port densities per node viable; dramatically reducing both the MSO’s Capex and Opex cost per RF port.”
