When cables are too long, they can disrupt the flow of information. Weaker or distorted electrical signals (information) can result into reduced speed, more errors, and sometimes no data transferred at all. When setting up networks, home entertainment systems, or any other machines that transmit information through wires, this is a major point to note.

What is the Prescribed Length of the Cables?
The prescribed length of cables refers to the maximum advisable length for optimum performance. It varies depending on the kind of cable in use. An example is if we take a 10BASE2 coaxial cable, its recommended size is approximately two hundred and fifty meters while that of 5 miles can be round about two miles away from the network station. To ensure that effective network resource utilization and latency avoidance are well maintained, these prescribed lengths should be observed by any networking technician.
Why the Prescribed Length is Important for the Cables?
- Signal Strength: Longer cables lead to weakened and distorted signals over long distances as electricity has to travel even further; hence, data can easily be lost or errors may occur.
- Optimal Performance: Cords are made and certified to work within specific lengths for reliable information transmission and network velocity. This could slow down the performance if those limits are crossed.
- Resource Efficiency: By using longer cords than necessary, network resources and power are wasted because signals need more energy to cover more prolonged lengths.
- Compatibility: The specified lengths depend on the kind of cable used and networking standards that exist as exceeding them might contravene compatibility mandates, leading to challenges with connectivity across different devices.
Adverse Effects of Using a Longer Length Cable than the Prescribed Length
- Signal Weakness: The electrical signal responsible for carrying the data becomes weaker and weaker with every step it takes over a very long cable. Consequently, this means that the signal becomes so weak that in some instances, it cannot be properly understood at the receiving end leading to data errors or entire loss of connection.
- Slower Speeds: Data can only move so quickly over a wire. As such, the longer the wire is, the more time it will take for a given signal to get from one point to another. This, in turn, lowers the rate at which information flows between devices connected by such a wire.
- Data Loss: In very long cables, sections of the data signal might become too weak or distorted as they travel along them. Thus, by the time they reach their destinations these could have caused some missing packages or corruption of packets which are small portions of information.
- Signal Reduction: The electric current strength or amplitude reduces as distance covered increases over cables. Weaker electric signals are generally vulnerable to interference or noise overpowering them.
- Delays: The longer the cable, the more time it takes for data to travel from one end to the other. These delays can build up and cause the whole network to feel sluggish and slow.
- Protocol Problems: Some network communication protocols have strict timing requirements. By using cables that are too long, these timing rules may be violated leading to malfunctioning or breakdown of the protocols.
- Interference: These long cables can act as antennas and easily pick up electrical noise and radio interference from the environment. This additional noise is mixed with the data signal.
- Troubleshooting Difficulty: Compared to shorter cables, one will find it difficult to trace an exact fault in a very long cable run if there are issues on the network.
- Higher Costs: Longer cables than necessary will mean that more materials are used during installation. Furthermore, running and managing such long cable lengths consumes more labor time and effort.
- Reliability Problems: Since they are longer, they also tend to be exposed for longer periods of time hence stand higher chances of being accidentally cut, crushed or physically tampered with across their length. Therefore damages might cause part or all of a network going down until repairs happen.
What Happens When You Use Cables Longer than the Prescribed Length – FAQs
Why can’t I just use a really long cable for my internet connection?
However, using an excessively long cable can make your internet signal too weak to function properly, so it’s better to avoid that.
I have some extra cable leftover from a previous installation. Is it okay to use it even though it’s longer than needed?
No, you should only use the right length of cable. This will result in slow speeds, interference and possibly lossing data if not done.
My neighbor’s wifi signal is weak. Can I run a really long ethernet cable from their router to my house to get better internet?
That would not be good because there is a maximum limit on the length at which Ethernet cables can be run before the quality of signals becomes very poor thereby undermining its functionality.
I want to connect my TV to my computer for gaming, but they are in different rooms far apart. Can I use any length HDMI cable?
HDMI cables also have prescribed maximum lengths – typically less than 50 feet – beyond which video and audio quality may deteriorate.
What happens if I accidentally use a cable that’s too long for my home network setup?
If you use cables that exceed the length recommendations, your network speed may be slow and you might face intermittent disconnection and data transfer errors.
How can I tell what the maximum recommended length is for a particular cable type?
You can consult the specifications provided by the manufacturer of the cable or check out standards for that specific type such as Ethernet and HDMI (Paul ). These stipulations arise from the physical characteristics of the cable used.
Does using a cable that’s too short also cause problems?
However if they are very brief they don’t degrade signal quality while excessively short cables increase interference from adjacent wires and electrical appliances.
