10Gb conection distance limits?

[HenryDays]

The title is pretty self explanatory ... what is the maximus length of an 10Gb cable , I red on wikipedia that the signal only lasts for 1 meter on copper based system, and in fiber can go to long distances , but the question is how long can go 10Gb conection?

Thank you for your answers

across how many cables?

across how many cables?

1 cable only, another way if getting 10gb speeds would be have 10 x gb cables with 2 x quadGb nics + dual Gb nic - this connection should last for 25 meters

[HenryDays]

But that way would be a.freat mess

Depending on the type of cable used, but cat6a is rated for 10GB at 100m (iirc).

When you say "10Gb cable" what exactly do you mean? There are numerous technologies and protocols that enable 10Gb speeds.

 

Do you mean 10Gb Ethernet? If so, then you can achieve 100 meters using Cat6a cable. You can achieve up to around 55 meters using original Cat6 as well. Furthermore you may be able to do limited (very short) runs of Cat5e, but I've seen no confirmation of this actually working.

 

So what you read on wikipedia (if indeed you read it there) was wrong. Cat6 and Cat6a are both copper cables, and can do well over 1 meter. Fiber Optic cable can indeed go farther though. Up to 80 km (Kilometers) with highly specialized cable. But it's also significantly more fragile, and more expensive when compared to Cat6/a.

You would need a channel bonding router/switch that supports that many simultaneously bonded connections. I do not know if such equipment even exists, but if it does, it won't be consumer level equipment. As stated above, if the cable run is only 25 meters, then you can use Cat6 or Cat6a. You would need a 10GBASE-T 10Gig Ethernet NIC though of course.

Yep, the doc you just linked says exactly what I said. If you scroll down to the table, 10BASE-T can do 100 meter runs with Cat6a or Cat 7, and 55 meter runs with Cat6.

 

Some very old 10Gig technologies were limited to 1 meter on copper, but that hasn't been the case in quite some time.
