Changing the network from 100Mb to 1Gb, does the cable also need to be replaced?

Question

Hello! I would like to speed up my network and go from 100Mb (Fast Ethernet) to 1000Mb (Gigabit Ethernet) ... Do I have to replace the network cable in addition to changing network cards?

szymon188 · Answer

It depends on what cable you have currently used. CAT 5 or 6 cables are used for gigabit networks.

How can I check? I have 8 lives, as probably everyone ... hmmm?

badboy84 · Answer

it should be printed on the cable, otherwise you won't check it 4-core cables (2 pairs) can also be used in 100Mb networks, but by the way, apart from the cable and cards, you have to remember about the rest of the equipment, i.e. switches, etc., everything that is on the way ...

I have bought Swish ... SMC but what should be written on this cable? Exactly because there are a lot of these signs? What symbol should I pay attention to?

So it doesn't matter if it will be cat 5 or cat 6?

badboy84 · Answer

preferably cat6 or something like that For example, I have a YFC cable on the cable certified for gigabit ethernet

It is true that the network is in the company and there are many computers, but when I checked how much it will take, it does not exceed 40% (I will check tomorrow) ... And the computers are strong ... 3Ghz processors, SATA etc ...

There is some program to diagnose the connection, test the connection ...
Is it possible to use a 1Gb network completely between computers connected by such a network when copying from disk to disk? Because it's hard for me to believe it somehow

I do not know why... ?

As my colleague badboy84 gigabit ethernet wrote, it will work on both cat 5 and cat 6 cables. cable construction for each category. Besides, there will be an imprint on the cable insulation of what category the cable is or in what technology it was made.

bartekpl · Answer

I recall my earlier questions so that they would not be forgotten :) I have something written on the cable at home: 4PR Cat. 5e IEC

szymon188 · Answer

1Gb / s is the theoretical speed of this connection so and only theoretically possible to achieve.

bartekpl · Answer

Well, yes, but I will get 80%?

szymon188 · Answer

It depends on many factors. Cable length, equipment performance, connection quality, etc.

bartekpl · Answer

szymon188, if you can, go to the gg, I wrote to you from my number. I would be grateful if we talked about the network for a moment because I am exchanging the network in the company and I need to educate myself

I have a question: I have an Ethernet giga on my motherboard (the card can detect cable lengths and test them quickly). I would like to make a connection between 2 computers in one network, does the crossover cable differ from that on 100Mb ??

bartekpl · Answer

and what program does it do?

jacekowski · Answer

it is not a matter of the program, but the card's electronics and it is most likely a marvell card (if only it had TCP-Offloading - it would be an ideal card)
and the crossover cable between the ordinary one differs only in that the ordinary one has the same order in both plugs and the crossover cable in one is changed

Changing the network from 100Mb to 1Gb, does the cable also need to be replaced?
