Design and implementation of the image transmission project on the fiber optic platform number 6
Due to the reception of our technical articles regarding the design and implementation of CCTV projects on the fiber optic platform, this time we have written another project for you that was implemented by Sepitam's technical team last month.
There are 6 zones in this project, the distance between them is about 500 meters.
According to the employer's request, 8 network cameras are installed in each zone and the images and data of all these cameras are monitored in the control room located 500 meters below zone 4.
In this project, various cabling methods have been investigated and finally the most optimal ones are as follows:
Consider point 4 as the hypothetical control room. From zones 1, 2, and 3 to the hypothetical control room, we consider a 12 core cable (red route) in which 4 cores are cut and transited in each zone, 2 cores are used and 2 cores are reserved (Spare) be.
From stations 5 and 6 to the hypothetical control room (same as zone 4), we have also thrown a 12-core cable (blue route) that we have fused 6 cores in each station, and another 12-core cable from the hypothetical control room to the main control room. We have dropped (green path).
If you pay attention to the hypothetical control room in the figure, i.e. zone 4, we have considered a patch panel for the left 12 core cable and a patch panel for the right 12 core cable and a patch panel for the bottom cable inside the rack. We have also considered a patch panel for the main control room.
For each zone, we consider a PoE switch with two SFP ports with technical number Sepitam-PS208E-DF. And we put a Duplex fiber optic module in each switch. We have 5 switches through which image data is sent on fiber.
To get this data, the best thing to do is to put our Sepitam-FS208F-DG switch inside our hypothetical control room. This has advantages that will be mentioned.
Because all the ports of this switch are uplink, connect one of its SFP ports to the patch panel corresponding to the lower 12 core cable (green path) and send the camera data to the monitoring room or the main control room through 2 cores. We send To receive these data, we have placed an Sepitam-MC11G-SSF media converter that has a bandwidth of 100/1000mbps as a receiver in the main control room. The advantages of this design are as follows:
1. All information from zones 1 to 6 has been transferred to the command center with only 2 choruses.
2. In points 1 to 3, there are two reserve cores, in points 5 and 6 there are four reserve cores, and there are 10 reserve cores to connect the command center with point four.
3. If we were to place the fiber switch in the command center, 2 major problems would arise:
A: There is no fiber optic cable left for reservation at any point.
B: The entire fiber strands of the command center were used up to point 4, and it was not possible to upgrade the system for the future.
C: Currently, there are facilities for sending network, voice, data and telephone.
By using this type of design, if the employer wants to transfer the network, voice, telephone or any other signal from his points to the monitoring room due to the presence of reservation channels, he can easily do this by adding fiber optic transmitter and receiver devices.
Always keep in mind in the implementation of fiber optic projects, don't just see the momentary demands of your employer. Try to do the fiber optic cabling in a way that can use the benefits of fiber in the best way with the cost it does. Intelligence in design will help in reducing the cost of implementation and will bring future perspective.
