1. Optical fibres are thinner

Optical fibres are known to being be extremely thin and smaller than any other type of metal wiring. How thin can optical fibres be? Aston University’s Photonics team Institute has over 300 km of optical fibre dedicated to the research of a high speed internet network, all within one research lab!

2. Optical fibres are lightweight

The thinner optical fibre also means that they are lighter. This makes it easier to transport large amounts of cable. The lighter weight of the cabling results in lower transportation costs and any risks associated with heavy lifting. The cable’s compact nature also means that it can be installed in very tight spaces.


3. Optical fibres are secure

Security is important to anyone transmitting private signals. It is far more difficult and costly to tap into an optical fibre than electrical wiring. This makes optical fibre cabling far more secure than normal wiring.

4. Optical fibres are efficient

The signals sent through copper wiring degrade relatively quickly and therefore need multiple substations to maintain a good signal quality. Suffering a poor internet connection? It’s likely you are on a copper network.

Signals sent through optical fibre do not degrade as quickly as those sent through a copper, resulting in less substations needed to retain the quality of the signal. The fewer the stations, the more efficient the transmission.


5. Optical fibres are weather safe

Since optical fibres carry light, rather than electrical signals, they are not affected by any changes in weather. Temperature, rain and lightning can all affect electrical signals transmitted through traditional cabling. The image bellow demonstrates a map of the world’s undersea optical fibre cabling.
