I. Overview
With the continuous and rapid development of the Internet, new business on the Internet, especially in recent years began to become popular in the network games, conference television, video on demand and other services, so that people's demand for network access bandwidth continues to increase; According to the relevant data analysis, the next 3 years, the average user bandwidth demand will The traditional access mode will not meet the demand of bandwidth.
Compared with other wired and wireless access technologies, fiber-optic access has unparalleled advantages in bandwidth capacity and coverage distance. With the advent and rapid maturation of low-cost gepon technology, coupled with the rapid decline of the cost of optical fiber and cable, the ideal of many operators to access network fiber optics can be realized.
On the one hand is the huge potential demand for bandwidth from emerging new businesses, on the other hand, it is technically possible to ensure that the user can accept the price of optical fiber access, in the "market demand" and "technological progress," the combination of two coaches can predict FTTH is about to enter a new era of large-scale business.
Second, the Beacon Communication FTTH development process
Beacon Communication Limited Liability company (Beacon Communication) is committed to independent research and development, production of high-quality metropolitan area Network and access network equipment and provide a full range of solutions. In FTTH field, the Beacon is a well-deserved leader. As early as 2000, undertook the National 863 Project-apon Research and Development, January 2004, the Beacon Communication undertook national 863 Project-gepon formally passed the national acceptance.
Beacon Communication currently has a very complete FTTH optical fiber access product line, including the AN5116 series and client-side equipment AN5006 series, to meet the operators of different sizes, different types of business needs. At present, the beacon communication in the country has a number of FTTH test engineering or commercial projects, has accumulated a wealth of implementation experience, is one of the most powerful FTTH suppliers.
Three, the Beacon communication FTTH Solution
1. Overall solution
As the mainstream supplier of network equipment in domestic telecommunication industry, Beacon Communication has a deep understanding of the demand of operators and the characteristics of telecom networks. Research and development of telecom-grade gepon products not only meet the latest IEEE802.3AH standards, but also can be compatible with the existing PSTN network and NGN network, can be achieved in a fiber transmission of ordinary telephone, broadband data, analog TV and other services, the real realization of the fiber-optic household, three network integration. As shown in the following illustration:
Beacon Communication FTTH Solution in the end of the use of self-developed AN5116 products. The local terminal equipment an5116-02 is a large-scale telecommunications products, network side interface can provide GE, E1 (V5.2), Analog TV and STM-1 optical port, respectively, connected to the data metropolitan Area Network, PSTN network, radio and television network and transmission network. The system uses the industry-leading "single fiber three wave" technology, through the an5116-02 of a variety of business through 1 optical fiber transmission to close to the user, connected to the optical branch of the passive optical splitter, branch optical fiber to connect the end user. The maximum tap ratio supported by this system is 1:64 and the maximum access distance is over 20 km.
Beacon Communication fully take into account the different operating environment needs, targeted to develop a suitable for different customer needs AN5006 series of user terminal products, can provide Fe, POTS, RF, E1, VDSL and other interfaces, user-friendly according to the actual need to flexibly choose FTTH, Fttb+lan, FTTB+VDSL, Ftto+wlan and many other optical fiber access solutions.
2. Multiple Business Solutions
Beacon Communication based on Gepon FTTH solution can achieve a variety of business integrated access, including: broadband data, voice, video and narrow-band line services.
The Beacon Communication FTTH provides the high bandwidth data service for the user, and uses the DBA technology to dynamically allocate the whole system bandwidth, so that users can enjoy higher peak bandwidth and improve the bandwidth utilization of the system.
The Beacon Communication FTTH Voice service solutions are available in two ways: based on traditional V5 solutions and VoIP solutions. For the traditional V5 solution, it is completely handled by the local equipment AN5116, without adding any external equipment, and the open V5 or PRI interface is used to dock with the existing PSTN network, and the existing network resources are fully utilized. For VoIP voice solutions, AN5116 the built-in call control module, At the same time support MGCP, h.248, SIP, H.323 protocol, can flexibly adapt to H.323 VoIP network and h.248 SoftSwitch network, and the AN5116 of SoftSwitch interface and many major manufacturers MGC docking success, openness is excellent.
Video services include a variety of business types, such as IPTV and CATV. For IPTV business, the communication FTTH system has no bottleneck structure design, provides the ultra-high speed bandwidth can guarantee the high quality information interaction and the high definition dynamic image transmission needs, is supports the IPTV the ideal access way, plus the perfect multicast protocol support and the maximum 20km coverage area, can easily meet the IPTV business network requirements. For the CATV business, the Beacon Communication in FTTH system for the CATV signal independent set 1550nm wavelength transparent transmission channel, on the client side ONU equipment directly provide RF RF interface to connect the TV, and support the evolution from analog TV to digital TV, and AN5116 system itself without any changes.
The Beacon Communication FTTH system supports the transparent two-layer simulation of TDM service, through tunneling and simulation technology, seamless transmission of service, timing and signaling information in packet switched networks, and convergence of large capacity TDM service, with STM-1 interface for upper allied, Easy to solve the E1 and other narrow-line services access.
The Beacon Communication FTTH System realizes the integrated access of a variety of services on one fiber. Is the true meaning of the "triple network integration", its powerful integrated business solutions, applicable to different occasions, the needs of different users for the operators to strive for multi-level customers and carry out differentiated services to provide strong support.
3. Line Solution
Beacon Communication is currently the industry can provide a full range of equipment and wiring solutions manufacturers in the leader. Beacon Communication for FTTH This day has been a lot of research, and through a number of actual FTTH project has accumulated rich experience, at present has formed a complete fiber-optic household wiring solutions.
The beacon communication can be provided with FTTH dedicated cables including: Indoor vent blowing construction of optical cable, road micro-cable, integrated optical fiber cable, vertical cabling cable, self-contained aerial cable, integrated wiring with special optical cable, single core users of soft optical cable, etc. to provide FTTH cable network supporting facilities include: fiber distribution frame, cable sub box, Various types of joint boxes, outdoor light junction box, user intelligent terminal box.
