Application and function of PON technology in monitoring network

With the continuous expansion of the coverage scale of "safe city", the number of network monitoring points has also increased dramatically. The problems such as power supply difficulty, transmission distance limitation, bandwidth bottleneck brought by a large number of webcams have brought resistance to the rapid development of "safe city". How to speed up the development of "safe city" and "smart security" and solve the problem of camera load and power supply is a thorny problem.
Although Poe power supply is used in group network to solve the problem of installation and power supply of monitoring camera, it can not solve the demand of long-distance transmission. There are serious bandwidth bottlenecks and transmission distance limitations in the network monitoring access part. Only by breaking through these can we meet the requirements of massive monitoring point access, IP networking and HD, and make the whole monitoring network play a maximum role. With the wide application of Poe technology, it is urgent to find a device that can support a wider range of network coverage.
Pon-poe network has the characteristics of simple construction, convenient maintenance, low cost and good stability, which can fully meet the requirements of high bandwidth, high quality and access diversity of video monitoring.
There are two parts in the application of PON technology, OLT and ONU. Among them, OLT series products can be used as the office equipment in PON system, converging access services and delivering them to IP network respectively; ONU series is a switch with POE function based on EPON Technology, which can be applied to network access layer equipment.
HT3404-8GC-2TF is a 4pon port office terminal (OLT) device, which is equipped with four fixed PON ports. It has the characteristics of high reliability, low cost, easy to use and flexible deployment. According to different user scenarios, the product can meet the application of FTTB, FTTC, FTTH and other access occasions, and is a good choice for operators to build EPON access network with low investment.
HT4200-EG1008P is the switch with POE function based on EPON Technology introduced by Hongteng optoelectronics. It integrates the optical network unit ONU and its Ethernet two-layer switching function. It can be used with OLT equipment at the office end to provide EPON access service and meet the networking requirements of FTTB / FTTO optical fiber to the building.
HT3404-8GC-2TF provides 4 PON ports, 8 Ge optical ports, 8 Ge electrical ports, and 2 10GE expansion SF + 10 Gigabit ports. Flexible design, support a variety of different types of man interface combination, can choose Gigabit or 10 Gigabit port according to the network situation. With the company's ht4200-eg1000p equipment, it can create a high cost-effective network monitoring suitable for long distance, optical fiber saving and cost saving.
In the network monitoring, PON + Poe networking mode and optical fiber transmission are used to break through the bottleneck of traditional cable transmission, so that the data can be covered in a large range and over a long distance, and the construction and maintenance are simpler.
The solution of PON + Poe has great advantages over the traditional way, which is simple and reasonable in networking, saves a lot of fiber resources, equipment installation space, and reduces network failure points. It integrates the mainstream PON technology and Poe technology, realizes the organic integration of PON and Poe, reduces the construction cost and maintenance cost, improves the investment income ratio of operators, and is a real maintainable, manageable and cost-effective solution.
