[Shenzhen, China, June 23, 2014]: Huawei, a leading global information and communications technology solutions provider, recently unveiled the industry's first Distributed Converged Cable Access Platform (CCAP) at the ANGACOM Exhibition in Cologne, Germany, making cost-effective multi-service convergence and service digitalization a reality for the MSO industry. Huawei also showcased the evolution roadmap of the DOCSIS 3.1-capable distributed CCAP product that protects carrier investment to the maximum extent.
At this year's ANGACOM Exhibition, Huawei's announcements of the distributed CCAP and DOCSIS 3.1 evolution have become hot topics in MSO access. Compared with traditional CMTS, D-CCAP can converge with FTTx, saving 70% of hub space, 50% of power consumption and 80% of trunk fiber resource. Huawei's DOCSIS 3.1-based distributed CCAP solution employs Orthogonal Frequency Division Multiple Access (OFDMA) in the upstream to support simultaneous access of multiple users over a single coaxial cable, and broadcasts data to downstream users divided into different groups using the multiple modulation profile (MMP) technology, drastically enhancing the spectrum efficiency. Synergizing the key technologies of DOCSIS 3.1, such as physical-layer high-order modulation (16K QAM downstream and 4K QAM upstream) and low-density parity-check (LDPC) codec, distributed CCAP delivers 2.3 Gbit/s downstream and 1 Gbit/s upstream over a single channel, making it the highest line rate possible over coaxial cables in the industry. Compared with DOCSIS 3.0, DOCSIS 3.1 is significantly enhanced in terms of spectrum efficiency and bandwidth, and is therefore able to deliver a smoother audiovisual experience with Internet services to users.
Huawei's DOCSIS 3.0-supporting distributed CCAP solution is able to smoothly evolve to DOCSIS 3.1. Leveraging the superior performance of DOCSIS 3.1 in high-order modulation at the physical layer, distributed CCAP helps carriers build ultra-broadband cable access networks, and extends the lifecycle of the existing hybrid fiber coaxial (HFC) networks by another decade.
"Paying close attention to the MSO market demands, Huawei has devoted energy to technology innovation, actively driving the standardization of distributed CCAP, and making significant contributions to MSO ultra-broadband network build-outs. The distributed CCAP solution we unveil at the Exhibition this year is a perfect combination of DOCSIS 3.1 and the distributed CCAP architecture. Therefore, the product is in line with the digitalization, convergence, and ultra-broadband smooth evolution strategies of MSO networks," said Mr. You Yiyong, President of Huawei's Access Network Product Line.
As a primary author of the C-DOCSIS standard, and an active advocate of the international standard for the distributed architecture access (DAA), Huawei has been committed to MSO network research, and strives to provide higher-bandwidth, faster and better convergence solutions. As a member of the CableLabs DOCSIS 3.1 standardization workgroup, Huawei has fully participated in development of the DOCSIS 3.1 standard and has contributed to many technical proposals.
