Fiber-optic cables have been taking over a growing amount of global internet infrastructure. This is happening foremost because of the incredible speed fiber lines offer for transmitting information, but that’s not the only advantage they offer. Fiber-optic cables are also more secure than traditional copper cables or wireless connections, and for that reason, security companies are starting to take notice.
How Fiber Optics Work
Cables like telephone wires and coaxial lines transmit electricity from place to place. By pulsing the electricity in certain ways, they can send both information and energy on the same wire. That’s why a landline telephone only needs one connection to work. Coaxial cables can’t send enough energy to power a TV, but in exchange, they can send a lot more information.
However, all of these connections move at the speed of electricity, and while that’s a very fast speed it’s not nearly the fastest thing around. Instead, that honor goes to the speed of light, which is what fiber-optic cables use to communicate. Using special fibers made of glass or plastic, a light that shines at one end of the cable can appear at the other end after moving almost 300 million meters per second. It’s the fastest speed that information can move, and locations with a fiber internet connection can get a gigabit per second or even more.
What Makes Fiber Optics Secure
In the security world, people worry about tapped wires and intercepted signals. While this isn’t the only way to steal or intercept information, it gives hackers and industrial spies a way to listen in on communications without having to do anything at the sending or receiving location. Instead, they can dig up an electric cable and attach a special device that reads the magnetic pulses that the wires give off.
However, fiber-optic cables don’t give off any magnetic signals. All they do is send light straight through the cable from one end to the other. Someone who wanted to intercept information would have to cut the cable itself, and that would break the connection and warn both sides that something’s happened to the line.
Why Use Fiber Optics With Security Systems
The biggest benefit to using fiber-optic cables in security systems is the fact that you can’t intercept or interfere with the signal, at least not without making the attempt obvious and very possibly breaking the cable beyond repair. At the same time, fiber-optic cables let security
cameras send high-definition video to the central hub at consistently high speeds. Sending that information wirelessly from several cameras at once would clog up the system, making it hard for visitors and employees to get a good speed.
Using fiber-optic cables for security systems makes a lot of sense thanks to its many benefits. The cables don’t respond to electric interference and can’t be tapped without breaking them, plus they transmit information so fast that you can set up as many high-definition security cameras as you want. If you haven’t switched over yet, you should consider how fiber optics could benefit your security system.
