For the ideal model of my country's FTTH construction scale and cost price in the next few years, telecom experts gave the answer at the FTTx technology salon held by Fiberhome recently.Mao Qian of Wuhan Academy of Posts said that the development goal of my country's FTTH is to make my country's FTTH users reach 61.9 million within the 10-year period from 2008 to 2017.The expansion of scale is bound to bring about price reduction. Zhang Chengliang of Beijing Telecom Research Institute predicts that when domestic FTTH installation users reach tens of millions, the FTTH installation cost can be controlled at around 600 yuan.Yu Jingwen of China Telecom Beijing Research Institute said: Reasonable planning and installation of lines will save the cost of each user's access bandwidth.Generally speaking, the factors involving different lines mainly include the distance from the user to the OLT, the user object (resident user or office user, multi-layer, high-rise or villa user object), and the wiring scheme (centralized or decentralized), specific to FTTx implementation There are also FTTH, FTTB and other modes. In particular, FTTB has achieved good application results in the current Huilongguan community in Beijing, and the installation price per household has been reduced to less than 1,000 yuan.For capacity expansion, one way is to leave space on the existing equipment. For example, when designing the line, the optical fiber has a certain proportion of redundancy. Research and develop 10GEPON and 10GPON standards.Regarding the operation and maintenance cost, there is no accurate data in China, but from the perspective of engineering construction, the construction model should be more conducive to the maintenance in future operations, Yu Jingwen said."FTTH has come to fruition." This is Mao Qian's image metaphor for the status quo of FTTH, but considering CAPEX and OPEX, building an FTTH network that meets people's needs, social development needs, and my country's scientific and technological development outline, also needs to be Up and down the industry chain is working hard to create a model suitable for China's FTTH development.The FTTX projects of Beijing Huilongguan Kuan HOUSE Villa Community and Huilongguan Cultural Residential Area adopted FTTH and FTTB construction schemes respectively, and were constructed by Beijing Communications using Fiberhome's GEPON equipment and cable solutions.The Kuan House community is a villa residential community with a total of 210 households, all of which use the FTTH access scheme.The central office equipment OLT is placed in the Netcom computer room in the community, and a multi-service ONU is placed in each user's home to provide home users with broadband data, IPTV, VoIP voice and other services at the same time. You can enjoy a variety of business services.This is a typical high-end residential fiber-to-the-home, and a typical project that realizes the integration of three networks, and has a strong demonstration role.Huilongguan Community is an affordable housing community, and the residents are ordinary citizens. The construction scale of the first phase has reached 6,000 households.In the network construction, a low-cost FTTB solution is adopted, and a corridor-type ONU is placed in each corridor. Multiple users in a corridor share one ONU, which can provide users with voice and broadband data access services at the same time.Beijing Communications has calculated that the average cost of network construction per user in this community is lower than that of traditional copper lines, and it has the conditions to be promoted in Beijing and even across the country.
