Technology Times > Scrolling News > TextAs the earliest telecom operator in my country to enter the FTTH market, Wuhan Telecom has carried out the construction of the first FTTH pilot project (Wuhan Changfei Apartment) and the first FTTH commercial project (Wuhan Zisong Community) in the country, and has since opened the FTTH Prelude to the development in China.In the early construction, Wuhan Telecom has implemented more than ten fiber-to-the-home projects, mainly using the FTTH network construction mode to provide data + voice + CATV + IPTV triple play services.Although this mode has huge bandwidth advantages and complete full-service provisioning capabilities, it is still difficult to popularize on a large scale at this stage because the initial investment cost is higher than that of traditional access technologies such as ADSL.With the continuous advancement of FTTH construction, Wuhan Telecom pays more attention to the investment income ratio of the network, and the concept of network construction is also more stable and pragmatic.Since 2007, Wuhan Telecom has successively implemented EPON+DSL, EPON+LAN, and rural informatization transformation in response to different scenarios of Wuhan residential construction, different needs of users, different environments of new and old areas, and different regions of cities and rural areas. The network construction model has been actively explored and piloted, and has achieved great success. It has become a local operator with the most complete application model and the largest application scale in China Telecom.Among the various construction modes explored, the EPON+LAN method has begun to be widely used.In August 2007, Wuhan Telecom carried out the first batch of FTTH construction work for 20 new residential quarters in the city center, with a total of about 20,000 lines, all of which were constructed using the FTTB+LAN method of EPON technology.In this project, FiberHome successfully won half of the shares, and the FTTB+LAN solution provided has achieved great success in the later project opening.This solution can not only effectively reduce the cost of network construction, but also provide complete services, which can meet the needs of fast and efficient network construction, and has achieved good results in the domestic FTTX market.With the successful application of the FTTB+LAN network construction model, Wuhan Telecom launched an open tender for the optical fiber access project of more than 60 new residential areas in the urban area in January 2008.The project still continues the construction method of FTTB+LAN in the early stage, with a user scale of 30,000 households, which is the largest single FTTH project in my country so far.Following that, in February 2008, Wuhan Telecom launched the rural informatization EPON project in the suburbs of Wuhan, using the FTTN+DSL construction model, with an estimated initial scale of nearly 50,000 lines.It can be seen from this series of tenders that Wuhan Telecom's "optical advance and copper retreat" has been fully accelerated, and its mature network construction model and rich engineering construction experience have important reference significance for other cities across the country to promote FTTX.Fiberhome has always played a very important role in the development of Wuhan Telecom's FTTX.In April 2005, the two parties worked together to successfully open the first domestic operator-led Zisong Garden FTTH commercial project, which opened the prelude to the commercial use of FTTH in my country.Afterwards, FiberHome also built a number of FTTH projects such as Wuhan Chuangye Street and Wuhan Contemporary International Garden, with nearly 40,000 users. Its rich business, mature performance and stable operation are well received by users.In addition, FiberHome has always stood in the perspective of the healthy development of the industry, actively carried out in-depth and all-round cooperation with Wuhan Telecom, and strived to provide leading product technologies and differentiated FTTX network construction models, helping Wuhan Telecom to continue to heat up. more success in the FTTH market.FTTH mode is mainly used in high-end residential quarters.The AN5116 system at the central office is placed in the computer room of the central office, providing service interfaces for uplinking to the metropolitan area network and softswitch platform.All the line parts are designed with no edge, and the outdoor optical switch box is placed in the green belt or basement of the community and other idle areas, and the optical splitter is placed in the optical switch.The user terminal adopts FiberHome FTTH type ONU AN5006 series equipment, which is placed in the intelligent terminal box in the user's home.The existing FTTH access cells have basically realized the integration of three networks and can provide voice, broadband, IPTV and CATV services at the same time.It has established an excellent brand reputation for Wuhan Telecom.The networking topology is as follows:Wuhan Telecom adopts Fiberhome EPON system and FTTB+LAN type ONU on a large scale for the construction of the community network: the central office AN5116 system is placed in the end office computer room to provide the service interface for uplink to the metropolitan area network and softswitch platform.All the line parts are designed with no edge, and the outdoor optical switch box is placed in the green belt or basement of the community and other idle areas, and the optical splitter is placed in the optical switch.The client side adopts Fiberhome MDU (LAN) type AN5006 series ONU equipment; according to the different distribution of users in residential buildings, it is used in combination for networking.The ONU equipment is placed in the corridor network terminal box, and the backup power supply is used to provide the voice service with a power failure endurance of more than 8 hours.The network topology is shown in the following figure:After Wuhan Telecom has carried out large-scale EPON construction for the urban access network, it is now turning its attention to the construction of the suburban village access project in Wuhan.Choose to use the EPON system platform to provide comprehensive access to broadband and narrow services.In the early stage, many remote urban/suburban operation and maintenance centers such as Hongshan opened the advanced education platform for party members. FiberHome MDU (DSL) type AN5006 series ONU equipment was used to provide ADSL2+ broadband access at each access point. All the narrowbands will be cut to the EPON network to carry at the same time, the wide and narrowbands will sink at the same time, and the optical fiber will completely replace the trunk copper cable, further realizing the light in and out of copper.About Sina┊About Sina┊Advertising Service┊Contact Us┊Recruitment Information┊Website Lawyer┊SINA English┊Member Registration┊Product Q&A┊Copyright © 1996-2008 SINA Corporation, All Rights Reserved
