Doubt about fiber optic connection

Hello people. I want to make an optical fiber laying on a fairly large installation at the request of a customer. I never did but I cheer up. I was reading about it and although I have enough information also some doubts. The main purpose is to connect IP cameras, but also use the optical fiber to connect a pair of fingerprint accesses, numerical lathes and welding robots, among other devices. From the main ruck I would start with the optical fiber from an optical swtich and I would always have switches with optical outputs / inputs and RJ45, and on these switches I would connect the ip cameras or the X device in question. The query is as follows: to each secondary switch should I arrive with a unique optical pair, or can I connect in cascade as with the conventional utp?

Hello mann_75 : The best thing to do is to arrive with a fiber roll in a topology of [i] star, half-mesh (Media red) or full-mesh ( Network complete). Although it also depends on the equipment you use in your infrastructure; since you usually have to configure each port that you use to do the repetition and in the same way, each team has the option to perform the cascade [/b] [/i] or not. Note that to connect cameras with FO it is best to use a media converter to reach analog or digital. I hope I have helped a little to clarify your doubt.

Thanks for your answer. So it would be better to start with different fiber optic cables to the converters you need at different points in the warehouse, for example.
But if in a straight line of 400 meters you need to place four converters then you would have to indent one cable to use the fibers tx and rx corresponding to each converter?

It has already been explained to you that there is no such thing as bleeding.
It looks like you've never had an F / O in your hand, and you're confusing it with an electric wire.
Have you ever done the same thing with a UTP? The same goes for FO.

Hello again mann_75:
Sorry for being late in responding. I'll try to explain as best I can.
If your customer is going to do a fiber optic installation, it is because he has the resources to invest in the infrastructure of his network, so I recommend the basics for your network. According to the structured cabling components, it would look like this:
Computer Room: Ethernet
Telecom Room: Fiber Optic / Ethernet
BackBone: Fiber Optic
Work Area: Ethernet / Fiber Optic

Of course, I was thinking of using a 12-wire FO cable in a 600-meter run, and then every 80 meters approx, open the cable and pull out two fibers to connect to a converter and from there to the switch I need for the cameras. Was he right? Sorry if some questions are redundant or maybe I do not use the specific terms but I live in an area of ​​difficult access to specialized courses and everything I learned was self-taught.

It does not make sense to re-raise what has already been explained in detail a few months ago. If you place several switches in cascade, and the first switch fails, you are out of communication on all the computers in the network. Regards!

I understand you and I thank you for your answers and the patience to answer my queries. As you can see, I am not a registered technician. In my area there is no way to access courses and / or training for fiber optics and I am trying to evacuate all my doubts before starting a fairly important job and which I encourage to perform.

When referring to cable bleeding, I wanted to take a 12-haired cable, open the sheath and pull out two fibers to connect to a switch converter and connect 5 or 6 cameras. Then do the same in the next section of wiring.
I have a 800 meter trip for cubrior with FO, and every 80 meters my idea was to place media converters to then put switches with a group of 5 or 6 ip cameras.
