Huawei's fiber coax integration solution helps upgrade the radio and television access network
at present, with the continuous deepening of the national broadband China strategy and the development of video IP, radio and television operators generally have the need to upgrade the network bandwidth. Due to the advantages of gradually reducing the cost of optical fiber and simple operation and maintenance, FTTH scheme has become the preferred scheme for radio and television broadband to meet people's needs through such processing. At the same time, coaxial cable is also a valuable resource for radio and television networks, especially in areas where optical fiber transformation cannot be carried out in urban areas. Coaxial d-ccap scheme has also become the focus of radio and television operators. Therefore, the coexistence of coaxial and optical fiber is the current situation of radio and television operators' networks, and the coexistence of both is not only a challenge for the construction planning department, but also the operation and maintenance problem has become a more prominent problem. Huawei is committed to the development and research of radio and television access solutions, launched the fiber coaxial fusion solution, and achieved the perfect integration of d-ccap and FTTH network solutions
1. The d-ccap scheme smoothly evolves to docsis3.1 to achieve Gigabit access. Based on the c-docsis standard, the d-ccap scheme is suitable for urban CMTS coaxial network areas. The d-ccap scheme is compatible with the current OSS system and cm terminals, and realizes 100m service distribution capacity; Point to multipoint network structure saves backbone optical fiber resources and network transformation investment; It can evolve to 10gpon+docsis3.1, and the technological evolution is guaranteed
Huawei has continued to invest in the d-ccap scheme, and 300 + top R & D engineers in six major research institutes around the world have achieved technological innovation: 1023 cm at the same time, the bottleneck of the development of large optical node business has been solved; The built-in eqam frequency point 0~16 is flexible and adjustable, which brings more flexible frequency point planning to radio and television operators; PNM (active network operation and maintenance), app and other operation and maintenance features simplify the traditional coaxial complex operation and maintenance mode, and provide customers with high-quality broadband experience
d-ccap series products are suitable for different bandwidth scenarios: the standard d-ccap products support the access capability of 16 frequency points/800m bandwidth, and are suitable for the scenarios of DOCSIS 2.0 to DOCSIS 3.0 expansion and 100m access. The cumulative commercial scale has exceeded 40000; The high-capacity d-ccap product supports the access capability of 32 frequency points/1.6g bandwidth, and is suitable for Gigabit access and video IP scenarios of radio and television operators. The product and video IP scheme have been mature and stable commercial in the world; Docsis3.1 products adopt advanced OFDM modulation mode, which can provide 10Gbps downlink bandwidth capacity at most. Step 3: check the tension machine system setting, which is comparable to FTTH scheme, which fully demonstrates the vitality of coaxial. Moreover, Huawei DOCSIS scheme has been commercially available in TDC in Denmark and VDF in New Zealand, creating a world leading d3.1 ultra wide coaxial network
second, the dual fiber three wave FTTH scheme helps radio and television achieve overtaking in curves
the dual fiber three wave FTTH scheme is based on PON technology and is suitable for rural networks and new residential areas. The ODN network replaces the original coaxial network to achieve passivity; Optical fiber replaces coaxial cable to save network construction investment; GPON 2.5G downlink bandwidth provides radio and television operators with 100m broadband service delivery capacity
dual fiber three wave ont provides PON and cable TV signal interfaces. Both cable TV broadcast services and data services use fiber to the home. Broadcast TV and data signals walk on two optical fibers respectively, which do not interfere with each other. The service and network are clear, which is in line with the IP trend of radio and television services. It is smoothly upgraded to 10gpon, and is compatible with current ODN and terminal devices
III. Ma5 ensures a wide range of speed continuous conditioning and uniform loading in the experimental process; 800 fiber coax fusion platform realizes the perfect integration of network construction and operation and maintenance
Radio and television operators FTTH and d-ccap are in parallel. Facing the pressure of construction and operation and maintenance, dual integration is imperative. Huawei ma5800 platform realizes the integration of network construction and maintenance: ma5800, as a fiber coax fusion platform, realizes the common frame construction of FTTH and d-ccap; Ma58 experimental machine host situation: horizontal structure 00 pioneered the router NP architecture to realize the OLT virtualization function. One OLT is virtualized into multiple OLTS to realize a common platform for home/customer services and reduce network construction investment; Huawei ibridge integrated operation and maintenance scheme realizes the automatic distribution mode of FTTH business similar to DOCSIS through the perfect connection between ibridge and the original DOCSIS distribution platform and U2000; Secondly, Huawei U2000 network management platform realizes the same platform maintenance of FTTH and DOCSIS solutions, with simple graphical interface and rich operation and maintenance functions, which perfectly solves the problems of business opening and operation and maintenance of radio and television operators
to sum up, Huawei's fiber-optic coaxial integration solution will help upgrade the radio and television access network. Secondly, as a leading global communication equipment supplier, Huawei will continue to invest in the field of DOCSIS and FTTH, commit to the integration and innovation of radio and television networks, actively promote industrial development, provide radio and television customers with the best technology and services, and help upgrade the radio and television network
