A city is a prefecture-level city in Jilin. In 2011, the main city began to transform the two-way network of the access network. The main mode is EPON+LAN, which provides broadband services and interactive TV services. The main push service is interactive TV service. For the IPQAM approach. Long Optical Technology EPON Solution.
According to user density and distribution of network nodes, the front-end equipment room covering large-scale users is equipped with a large-capacity, carrier-grade rack-mounted OLT device, the C8000/C8500. This type of device features excellent performance, stability and reliability, and a single full-capacity capacity of up to 40/80. PON port, and can provide 1+1 main control board protection, power supply and fan protection. It is very suitable for the dense business deployment of the city. The C2000 is a box-type OLT device that covers small and medium-sized users and has a single fully-equipped capacity of up to 16 PON ports. It can provide power and fan protection, and supports long-distance transmission of 50 KM to meet long-haul optical nodes. Transmission requirements.
According to different scenarios, Long Optical Technology provides targeted FTTB solutions. For multi-unit residential buildings, the use of "FTTB + corridor switches + Category 5 homes" approach, to appropriately reduce the cost of coverage. For users of high-rise residential communities with high service access rates, the "FTTB+Five-line-to-home" approach is adopted, and network maintenance workload is further reduced.
At present, basically 200,000 users in urban areas are covered by two-way services.
