What is the best way to stretch the network over a distance of ~ 300m

Question

Computer networks

Good afternoon. I don't have much experience in building networks, I ask for help.

There are 2 warehouses, in the first warehouse there is a network, the task is to connect the second warehouse to the network. The minimum distance between warehouses is up to 300m. The network will be used to connect to the terminal server in the first warehouse. There will be many users in the future, so I would like the connection speed to be at least 1 Gbps. The maximum distance between the server and computers in the second warehouse will be 400m.

The first thing that came to mind was optical fiber, but after googling, I came to the conclusion that it is not so cheap.

Can you tell me what other options there are?

Answer 1

tocha4 optics are very different, as are transceivers. Range can vary from hundreds of meters to tens of kilometers.
Pilat PoE will not increase the range of data transmission in any way.
topbanana if you need high quality and for a long time, then still optics. Common inexpensive multi-mode, 1000base-sx transceivers.

Answer 2

That year, I was in a similar situation, eventually put optics. For an 8-core cable with a carrying cable of 500 meters + all the piping to it with installation, it cost $ 1200 + $ 300 cable unwelding.

Answer 3

We use Ubiquti equipment at a distance of 500 meters, stable 100Mbps over the air.
For terminal sessions, this is through the roof.

Answer 4

As for intermediate switches, there is PoE (Power-over-Ethernet) and switches that support it, maybe this is an option. But whether it will be cheaper than optics - it must be considered. Interference still all sorts can be or suddenly appear.
Maybe it's easier to put a second server and limit yourself to a slow connection? Megabit speeds can be obtained in various ways - up to communication over the air within the line of sight.

Answer 5

It was the same task. 400 m between the buildings decided on wifi got cliffs and loaded air. as a result, a third-party organization extended the optics for 72,000 rubles. We haven't had any problems for a year now. Optics is the most reliable and easiest option.

Answer 6

And do not forget to install gigabit switches) But seriously, most often the following recommendations are found along the length of the cable:
thin coaxial - 185 m, twisted pair - 100 m, fiber - 1.4 km.
So either 2 intermediate switches / hubs, or ask the provider, for a moderate fee, to be connected with their own channel.

Answer 7

shop.nag.ru/catalog/00002.Marshrutizatory/08454.MikroTik/11011.RBSEXTANTG5HPnD
will shoot at least 5km
Just what the hell do you need gigabit for terminals? I think you don’t have half a hundred thousand employees who will go through it

Answer 8

I have a warehouse of almost 200 meters, now it is twisted and the switch is in the middle, it works, but it strains the ping. So, as they say above - optics

Answer 9

Not so long ago, I put UTP 6e at 260 meters inside the building, in some places it lies next to power cables, it gives out 1 Gb and stable ping is adequate.

Answer 10

For long UTP segments (> 100 m.) , here in "B3" it is very clearly explained why, and this technology limitation is not related to signal attenuation, shielded / unshielded cable.
So, for pulling such segments, special UTP Repeater devices have long been used, and if in Russian it is “twisted pair signal repeater”. They are usually PoE powered devices, so you will need special switches, or PoE injectors .
And you will be happy. From practice - in this way they built a gigabit segment at 600m. (there was no way to get close with the optics), though they messed up a little - the repeaters were every 150m. (and not 100m as expected), but in the end everything works well, the network passed the categorization - UTP 5e

Answer 11

Opt for optics if you need stability. Especially if you lay a line through the air, since after the first thunderstorm the copper line will most likely stop functioning :(

Answer 12

If you create exactly gigabit for a long time and reliably, then optics, as has already been said many times.
Hub is certainly a beautiful word, but thank God they don't exist at the present time :-).
140 meters of FTP5E + 100 meters of FTP5E switch POe + have been laid next to it. The cable is of high quality, but it was originally planned to be 6 categories. So I hope to improve.
When connecting two computers at the ends of the channel, the speed is 300 megabits.

Answer 13

Just solved a similar problem and solved it once and for all. The distance between the two buildings is 216 meters.
If the twisted pair is stretched, then we twist on both sides, respectively, orange with brown pairs and green with blue, so that we get 2 thick wires. Then we take the pilot, cut the cable from the pilot and fasten it on one side and the other so that we get a 220 meter extension cable. Then, on the one hand, we insert the plug into the socket through the tee, on the other hand, power appears in the pilot's socket. Then we plug it into the tee (where the pilot plug is) and into the pilot using the Powerline adapter (I used a cheap TP-LINK on the box it says up to 300m on the mains, the issue price is about 1700 rubles per pair.). As a result, the connection speed was obtained when copying a file from the server on one side to the computer on the other, about 80 Mbps (copies approximately 8.2-8.3 MB per second.)
