For those who stay in a very giant dwelling and want to join units to your community through Ethernet cable as an alternative of utilizing Wi-Fi, you could be asking the query: How far are you able to run an Ethernet cable?

A single run of Ethernet cable is designed to work at a most distance of 100 meters, or 328 toes. A size longer than this can lead to points similar to dropped packets, diminished efficiency and lack of sign, significantly when utilizing Cat5 cable as a result of being restricted to 100 Mbps.

You might be able to exceed this restrict, nevertheless, you’ll in all probability discover that your connectivity speeds lower together with the general reliability of your community. Let’s check out some options to utilizing a single run of Ethernet cable that exceeds 100 meters must you want it.

How Far Can You Run an Ethernet Cable?

A single run of Ethernet cable is designed to work over a most distance of 100 meters, or 328 toes.

Past 100 meters, the sign will start to weaken and presumably cut back the general pace and reliability of the community connection.

The 100-meter restrict is a advice by the producer.

A cable that extends previous 100 meters could nicely nonetheless work, however the possibilities of connectivity points improve the additional you push this restrict.

The purpose through which community connectivity drops fully will range from one cable to the following, therefore the producers recommending that you just don’t exceed a size of 100 meters for a single run of cable.

Why Is There a Restrict?

In contrast to fiber which may carry and keep a sign over huge distances of round 60 miles, Ethernet cable is rather more restricted because of the electrical alerts degrading over longer distances.

That is very true when extremely skinny wires are used, as they're in Ethernet cable.

The additional {the electrical} sign is pushed, the extra delicate the info touring alongside it turns into, probably leading to degradation.

It could be tempting to make use of fiber inside your house community, however for many individuals, it's unlikely that you'll ever strategy the 100 meter restrict of ordinary Ethernet. Plus, fiber can be fully overkill and work out to be fairly costly.

Don’t fear although, as there are strategies of extending a community connection over 100 meters ought to you should.

Does a Longer Cable Scale back Speeds?

Inside motive, longer runs of Ethernet cable won't lead to diminished obtain or add speeds.

If utilizing Cat5e cable that has a most transmission pace of 1 Gbps, the speeds you obtain will probably be just about the identical no matter whether or not it's a 1-meter run or a 100-meter run.

Must you be utilizing an older type of Ethernet cable like Cat5, although, you usually tend to see a lower in pace the longer the cable is.

The take-home message is that you're extra more likely to get away with sustaining the pace over an extended run if utilizing Cat5e or Cat6 cable that's able to 1 Gbps in contrast with Cat5 which is proscribed to 100 Mbps.

Methods to Measure the Size of a Cable

When measuring the size of your Ethernet cable to see in case you are approaching that 100-meter restrict, you will need to keep in mind that this restrict is for a single run.

You aren't restricted to 100 meters whole out of your router to the machine you want to join.

Listed below are a couple of other ways you possibly can measure the size of an Ethernet cable, with some being extra sensible than others:

  • Tape Measure

Though utilizing a fundamental tape measure could also be okay to measure shorter lengths of cable,  it isn’t actually sensible for something over 10 meters.

You have to to have entry to the complete run of cable with a purpose to measure it precisely in addition to having a tape measure that's really lengthy sufficient.

  • Footage Markings

Most bulk reels of Ethernet cable may have footage markings on the skin shielding.

That is okay in case you are solely simply beginning a brand new reel of cabling as these markings are actually solely supposed on letting you understand how a lot cable stays within the field.

To be able to measure the cable, you would want to know the quantity on both finish of the cable and still have confidence that nothing has been spliced alongside the way in which.

Identical to utilizing a tape measure, it's potential to measure the size of a cable utilizing this methodology however isn’t beneficial.

  • Pre-made Ethernet Cable

For those who would like to not should make your individual Ethernet cable and need the comfort of them being pre-made, the size of the cable will clearly be seen within the product description.

Though you get to know the size of the cable right away, shopping for pre-made cables can work out to be fairly costly in comparison with making your individual, particularly for those who want many separate cables at differing lengths.

  • Cable Tester

If you'd like the simplest resolution and the most effective outcomes, use a community testing instrument to measure the size of a run of Ethernet cable.

Along with merely measuring the size of cable, these invaluable instruments additionally produce other helpful options similar to certifying the cable, telling you the speeds throughout the run and even having the ability to save the outcomes and export them for record-keeping.

Can an Ethernet Cable Be Prolonged?

It's potential to increase the attain of Ethernet cable; it simply includes a bit of additional tools.

Keep in mind you possibly can’t exceed the 100-meter restrict for a single run of cable, however you possibly can place a community change within the center to increase the general attain.

The change doesn’t even should be significantly near both the router or the machine.

So long as the cable between the router and the change and the opposite cable between the change and your machine are each lower than 100 meters lengthy every, the router and machine will nonetheless be capable to talk with one another.

It's potential to get small Ethernet extenders as an alternative of utilizing a community change, nevertheless, it's endorsed that these solely be used quickly and shouldn’t be a everlasting resolution

If you should lengthen an Ethernet connection past 100 meters, my suggestion can be to spend money on a fundamental community change as it would do the job completely while being fairly cheap to purchase.

Can an Ethernet Cable Be Run Outdoor?

The vary of a single Ethernet cable continues to be 100 meters, no matter whether or not it's being run indoors or exterior.

It's definitely potential to run an Ethernet cable outdoor ought to you should join one other constructing or outhouse to your community.

Though it's potential to make use of common Ethernet cable that you'd possible use indoors, it's endorsed to make use of weatherproof cabling as an alternative.

Abnormal Ethernet cable isn't designed for use outdoor, with temperature and humidity presumably shortening the lifespan of the cable.

Given the casing on an abnormal Ethernet cable is especially skinny, the wires inside can deteriorate shortly when left uncovered exterior.

For those who completely should use the Ethernet cable you might have mendacity round as an alternative of shopping for a reel that's weatherproof, my advice can be to deal with it inside a conduit similar to a PVC pipe that's weatherproof.

This pipe can then be buried underground to guard it additional. Simply be sure to maintain it away from any electrical cabling which may be close by or the rest that would lead to electrical interference.

That being as an alternative, I'd nonetheless counsel utilizing high-quality Ethernet cable that has been designed to be weatherproof must you want to run Ethernet outdoor. Even protecting conduits can fail in excessive circumstances.


A single run of Ethernet cable is designed to perform at a most distance of 100 meters, or 328 toes.

It could be potential to exceed this restrict while sustaining community connectivity, however the possibilities of connectivity points improve together with the next probability of diminished speeds and general reliability. 

Do not forget that this restrict is for a single run of Ethernet cable.

If you should lengthen a connection past 100 meters, my advice is to get a fundamental community change and place it between your router and the machine you want to join.

So long as each cables (one between the router and the change and the opposite between the change and the machine) are every lower than 100 meters lengthy every, a secure and dependable connection must be maintained.
