Monitoring project fiber networking examples, these four methods are very practical

Many friends have repeatedly asked how to network various monitoring projects? Traditional monitoring networking methods are quite familiar to everyone. In the past two years, fiber optic monitoring networking has become popular. Let's take a look at these four types of fiber optic networking system diagrams.

Monitoring fiber optic network topology diagram

1. Ordinary application

Mainly for limited network cable distance, fiber optic transceivers can be used, which may be a common type of networking in our daily lives.

2. One on one transmission method

This is a common application of fiber optic transceivers, which are commonly used in small and medium-sized long-distance networks, with only one pair of fiber optic transceivers being the most obvious.

3. Application of Fiber Optic Networking in Large scale Monitoring Projects

Convergent fiber optic transceivers are commonly used in some small network monitoring projects as a many to one connection method, also known as fiber optic aggregation switches.

The 4-fiber 1/2 electric or 8-fiber 1/2 electric fiber optic switch on the server room side directly replaces multiple 1-fiber 1 electric fiber optic transceivers, and is directly connected to the NVR through the gigabit network port of the fiber optic switch, reducing the application of one network switch on the server room side.

4. PON network monitoring topology diagram

The output image signals and digital video streams of cameras at each monitoring point are connected to PON through ONU devices, and then through optical splitters to achieve multi-point access.  

PON consists of OLT (Optical Line Terminal), User Side ONU (Optical Network Unit), and ODN (Optical Distribution Network).

PON bearer technology, as the mainstream access network networking technology in the industry, has a simple network structure and high system stability; Strong network adaptability, able to flexibly respond to significant changes in system functionality and performance requirements; There are various types of access services, which can better solve the problems of wide coverage of video surveillance systems, uncertain access points, and digitalization of front-end equipment. It has excellent adaptability.  

PON has better applications in large-scale monitoring projects such as long-distance or remote monitoring.
