Making the call on the right cabling solution for your network can be difficult without fully understanding and appreciating the differences between cables. It can be tempting to go with the cheapest cabling option, but this could end up costing you in the long run. The key to making the right choice is being educated as to the differences between copper and fibre cabling, and aligning your need and individual circumstances to the right choice of cabling.
Copper Versus Fibre: 4 Major Differences
Pricing
While copper cabling continues to be cheaper than fibre, the reality is that cheaper is really a relative term. While fibre is a bit pricier initially, the cost is often far outweighed by the benefits related to having this type of cabling long-term. A key reason why fibre is also often expensive is due to the cost of hardware associated with fibre-cabled networks. However, these costs are slowly coming down as technology advancements occur.
Security
Copper cabling is easier to tap than fibre cabling. Fibre cabling doesn't radiate signals, and once tapped will leak light, making it easy to spot, as this often causes the whole system to fail. In an age where data is an asset and is so valuable, it's prudent to choose the most secure cabling option you can.
Reliability
Fibre cabling is undeniably more reliable than copper cabling, due to its resistance to the environmental factors that adversely affect copper cabling. It's also immune to electrometric interference, radio interference, crosstalk and impedance problems.
When pulling network cabling during installation, fibre is able to withstand an up to 200-pound tension limit in comparison to copper's 25-pound tension limit.It can also be submerged in water, and is less susceptible to temperature fluctuations than copper cabling.
Bandwidth
Copper cabling provides less bandwidth than fibre. While copper cabling is still a viable option for industrial applications, it isn't futureproof. The bandwidth provided by fibre cabling offers data transmission speeds of up to 10Gb/s, and provide the opportunity to better plan for "bandwidth creep" as time progresses. Fibre is also able to retain its bandwidth over greater distances in comparison to copper cabling.
Selecting the correct cabling for your needs is important. If your budget won't stretch to accommodate fibre cabling, and copper cabling can meet your needs, then it's the right solution for you. At the same time, you won't be sorry if you squeeze out the extra budget needed for the fibre cabling, as it offers so many advantages over copper. A network professional can help you evaluate your individual cabling needs, and can advise you on the best solution for the job.
