Is PON network access the best way for remote monitoring?
Video surveillance is everywhere, whether it is the streets of a city, the community, the campus, or other public places. With the increasing demand for network monitoring, there are bandwidth bottlenecks and transmission distance limitations in current access modes. How to better ensure the access, network, and high-definition of massive monitoring points is not a simple matter.
As a result, PON access methods with high-bandwidth and long-distance transmission have become the primary choice for many remote monitoring and engineering vendors.
With PON access method, high bandwidth can meet the requirements of high-definition monitoring, high stability can reduce maintenance costs, a variety of access methods can easily deploy a variety of networks, and PoE technology can also be used to solve camera power supply problems. For example, Feng Runda's EPS5081 is an ONU with PoE function.
In general, PON access is a better technology choice because it meets the requirements of large-scale, high-quality, high-stability massive-scale access to video surveillance.
The advantages of PON in network monitoring:
1, Relatively low cost, simple maintenance, easy to expand, easy to upgrade. The PON structure does not need power and no electronic components during transmission, so it is easy to lay and basically does not require maintenance. The long-term operation cost and management cost are greatly saved; the EPON system has little overhead on the central office, high degree of modularity, and initial system investment. Low, easy to expand, and high return on investment; PON systems are future-oriented technologies, and most PON systems are multi-service platforms, which is a good choice for transitioning to all-IP networks.
2, provides very high bandwidth. PON can provide symmetrical 1.25Gb/s bandwidth for uplink and downlink, and can upgrade to 10Gb/s with the development of Ethernet technology.
3, a large range of services. PON, as a kind of point-to-multipoint network, uses a fan-shaped structure to save limited fiber-optic cable resources and serve a large number of users.
4, flexible bandwidth allocation, service guarantee. There is a complete system for allocating and guaranteeing bandwidth. The PON can implement bandwidth allocation for each access point through DiffServ, PQ/WFQ, WRED, etc., and guarantee the QoS of each user. The dynamic bandwidth division method can conveniently realize that high-priority data is always located at the beginning of a frame, effectively reducing the delay and delay jitter of high-level data, and at the same time when a new ONU joins in initialization, the high-priority data It is not interrupted, ensuring its low latency requirement; it controls the amount of priority data received at the OLU end to prevent packet loss due to improper distribution.
