From one street twisted pair of 200 meters to make two - is it possible?

Question

Computer networks

Hello.
There is a street whirlwind, ~200 meters. From point A to point B. The Internet 10 Mbps comes through it from the receiver from the fiber optic, the receiver at point A.
There was a need to make a separate channel, from separate optics at point A, I will put the receiver there at point A. But pull from the second receiver I don't want another street whirlwind. I just want to cut the already existing twist, the Internet goes through 4 cores, and turn one cable of the already thrown twist into two.
Could this cause shielding problems? It's strange that in general a normal connection at such a distance over the whirlwind now, maybe because 10 Mbps is just an Internet ... The second channel will also be 10 Mbps.

Answer 1

Yes, go ahead and do it. At the dawn of LANs in the 2000s, this was done very often. Maybe now they also hang snot.

Answer 2

Can. There are ready-made Y-adapters, or you can crimp the plugs yourself.
You may only have to transfer the equipment forcibly to 100 megabits.

Answer 3

Normally, the "extra" four cores are used as a screen. At 100 megabits or gigabit, this makes a noticeable difference, but at 10 megabits, it's likely "and so it will do."

Answer 4

200м витухой и по улице, без повторителей это сильно, уж лучше поставьте радиомост будет и стабильней и скорость до 25 можно отжать.
А так тут гадание на кофейной гуще и решение можно получить только опытным путем. Т.к. крайне мало оборудования может работать на таких расстояниях и если ваш медиаконвертер к примеру его худо-бедно выдерживает, то пара уже может мешать друг другу помехами и L2 свитч, для создания VLAN туннелей, тоже может не пробить такое расстояние.
Так что тут стабильных и бескомпромисных/безотказных 3 варианта:
1. Радиомост - пара уличных точек/маршрутизаторов - при прямой видимости самый лучший вариант
2. Всетаки заморочиться и протянуть эти 200м волокном чтобы поставить медяки уже на месте
3. Поставить пару VDSL модемов - стабильная сеть по одной паре до 2км

Answer 5

This is done quite often where they saved on SCS, or, for example, like yours, pull the wire with crowbars. Of course, the speed will be - what will it be, but for 10Mb, I think it will not be noticeable.

Answer 6

There are two separate questions here. You can use a 4-pair cable as two 2-pair ones, I did it more than once. I even put signals from two different networks in one cable. But ... with network segments no longer than the standard length, i.e. 100 m.
And here - 200. Here, at 200, this trick may not slip through. What it will be expressed in (in increased failure, packet loss, speed reduction, or something else) - I find it difficult to guess, I have to try.
