The project of transmitting different signals on the fiber optic substrate No.2

How to transit fiber optic cable:

As it is clear from the diagram, a 24 core cable goes from the monitoring room to the first station and 8 cores are implemented and the next 16 cores are implemented to the second station where 8 cores are implemented and the remaining 8 cores are implemented and pigtailed for the third station.

A 24K cable for the monitoring room to the fourth, fifth, and sixth stations, and a 24K cable from the monitoring room for the seventh, eighth, and ninth stations are similarly cabled, fusion, and pigtailed. In fact, in the central station, 3 patch panels of 24 ports have been considered for the fusion of all 3 24-core cables.

Considering that an optical fiber transmitter device (occupying one fiber optic core) and a 16-port switch (occupying two fiber optic cores) are placed in each station, out of the 8 cores that enter each station and are pigtailed, 3 cores are occupied and 5 Chorus is also considered as Spare.

If we want to consider more cores as spare, we can consider 24 cores cable for each 2 stations, in this case, the number of fusions and the number of passive equipment including: patch panels, pigtails and adapters will increase. The decision in this regard depends on the employer's foresight and the amount of money he wants to spend on the project.

How to connect signals:

Considering that in each zone, there are 5 data (including 3 RS485 and 2 RS232 two-way and 5 two-way contact signals and 7 telephone line channels for connection), an optical fiber transmitter and receiver device for these signals is designed. and is used to transmit all these described signals on a single-mode fiber optic core with a transmission capacity of up to 20 km.

And likewise, in each zone, a 16-port switch with 2 Combo SFP ports has been considered for each station's internal network transmission. Each of these switches is transferred to the fiber substrate through the SFP module and sends its data to the central station. In the central station to collect the data of these 9 switches, 2 optical fiber switches are considered. From the uplink of this switch, we connect the cores and other possible switches that are used in the central station itself to a switch with 100/1000mbps bandwidth, the uplink of this switch is finally connected to the server.

In this plan, by choosing the most optimal equipment, the ability to connect the most diverse signals on the optical fiber substrate is provided. Moreover, foresight is also done to connect unexpected signals and the remaining cores on the path can be used to transmit other signals.

All the communication products used in this project are from the reputable Sepitam brand, which have a two-year replacement warranty and 10-year after-sales service.
