On March 31, 2015, Huawei recently released the second-generation Distributed Converged Cable Access Platform (D-CCAP) solution at China International Broadcasting Network. The solution will increase the bandwidth of current coaxial cable access from Gigabit to Gigabit, and will have the ability to evolve to 10GPON+DOCSIS 3.1 (Data Over Cable Service Interface Specification) in the future, which can further increase the bandwidth to 10G. In addition, a single CMC (Coaxial Media Converter) device supports up to 1,000 simultaneous users of DOCSIS 3.0 broadband users. Its coverage capability is four times that of current industry solutions, significantly reducing network construction and maintenance costs.
With the continuous deepening of the triple play strategy, the current C-DOCSIS has become the mainstream construction method for broadband access networks. Huawei's first-generation D-CCAP solution is based on the C-DOCSIS standard and meets international standards. So far, mainstream MSO (Multiple System Operator) operators in China, Switzerland, France, Japan, Russia, and Brazil have achieved commercial scale. The second-generation D-CCAP solution released by Huawei on this first-generation basis has enhanced bandwidth, user capacity, service, and operation and maintenance capabilities. It has "Gigabit bandwidth, thousands of access, intelligent services, and centralized operation and maintenance." specialty.
First of all, the CMC equipment has been upgraded from the original 16 downlink channels to 32, with an access bandwidth of up to 1.6Gbps, and its bandwidth capability is comparable to FTTH. In the future, upgrades to 10GPON+DOCSIS 3.1 can be used to achieve a maximum of 10Gbps bandwidth. Secondly, through enhancements. With the chip processing capability, a single CMC device can support 1000 simultaneous users online, and a single OLT (Optical Line Terminal, Optical Line Terminal) can achieve 64,000 simultaneous users online, which is comparable to the network coverage of a traditional CMTS (Cable Modem Termination System). . In addition, through the OLT's built-in intelligent processing board and smart home terminal, it can help broadcasters extend their business to smart homes and smart companies, thereby boosting business revenue. Finally, through the converged management platform, a unique coaxial line monitoring module is built in to help operators reduce the introduction of external line monitoring systems and professional instruments, thus saving investment in operation and maintenance.
Huawei has long been committed to the integration of ultra-broadband innovations in broadcasting and television networks. Huawei is not only one of the major drafters of the domestic C-DOCSIS standard, but also actively participates in the development of the international DOCSIS 3.1 standard. Huawei took the lead in presenting the DOCSIS3.1 prototype at SCTE 2013 in North America. In the DOCSIS 3.1 interoperability test conducted by CableLabs at the end of 2014, Huawei was the only manufacturer with successful interoperability between upstream and downstream of DOCSIS 3.1. Both are far ahead.
