Introduction

Fiber optic cables are a type of optical fiber that transmit data at high speeds and provide a secure connection between two devices. They're used in computers, routers, servers, printers, and other electronic equipment. Fiber optic cables work by sending light down an optical fiber which can carry digital information at speeds up to 10 gigabits per second (Gbps).

Fiber-optic cables

A fiber-optic cable contains anywhere from a few to 100s of optical fibers within a plastic casing. Compared to traditional electrical wires, they can transfer data messages hundreds of kilometers away in the form of light. Other names for them include optical cables and optical fiber cables. Additionally, because they are comprised of glass and not metal, fiber-optic cables are not slowed down by electromagnetic interference brought on by lightning. Furthermore, fiber cables are safer since they cannot ignite or carry current.

How do fiber optic cables work?

In understanding how data is sent through fiber optic cables, it’s important to note that there are multiple components involved in the construction of an optical fiber that is all required to ensure they work properly. The glass strands themselves are central to the system working - but there are also some other key parts that all play a role in successful data transfer along optical fibers.

In order to transmit data "pulses" along the strands of transparent glass or plastic tubing at the center of the cable, there must first be a source of light. This is usually created either using a tiny laser or by an LED source, that receives input signals received from the transmitter circuit board and converts it into a light pulse before bouncing it through the fiber cores.

Secondly, it’s key that the glass fibers themselves are surrounded by an additional glass or plastic cladding layer, which will have a different refractive index for light passing through it than the core strands. These refractive differences between the cladding and the glass fibers it surrounds are what allow the incoming light pulses to be bent at particular angles as it travels the length of the cable.

What are fiber optic cables made of?

As mentioned above, fiber optic cables can be built of a variety of materials and parts, although the core strands are typically made of glass (silica) and/or plastic.

Due to their improved flexibility, reduced weight, and resistance to bending and shock, plastic optical fibers are typically more affordable and simpler to work with. They are typically utilized in situations where lower data rates and speeds are acceptable and where there is a decreased risk of mechanical stress, such as in slower, shorter-distance lines as part of residential, commercial, or automobile networks.

Advantages of optical fiber cables

As previously noted, fiber optic cabling has several key characteristics that give it a clear advantage over traditional metal conductor cables in several important criteria. These include:

• Bandwidth and data transfer - Older metal data cables, usually copper, offer relatively limited bandwidth compared to fiber optics. Copper-type communication cabling has been originally created to transmit voice signals, which don’t require as much bandwidth for mass data transfer as several modern applications presently demand.

• Speed - Using light pulses as the primary source of information conveyance gives fiber optic cables a huge speed advantage when compared to other modes of data transfer. In this aspect, fiber will typically perform significantly better than even high-grade (Cat5 or Cat6) copper cables.

• Distance - As well as being lightning fast, fiber optic cables can also carry their signals over much longer distances than traditional cabling types due to their low rate of signal power loss. Copper cables are usually cited as having a 328-foot limitation in terms of decent quality transfer distance; by contrast, certain single fiber optics can carry a signal over hundreds of kilometers given the right combination of materials, signal type (wavelength), and network setup.

• Interference - Since fiber optic cables don't really transport electrical signals, they offer much better interference protection than conventional metal cable types. As a result, their capacity to send data swiftly across much greater distances without suffering significantly from signal degradation is increased.

• Safety and reliability - Another difference between the optical fiber and copper cable is that the glass versions tend to be much thinner, lighter, and yet sturdier, making them built to endure much bigger pull forces and therefore less likely to suffer damage or breakage all over long runs than similar lengths of metal cabling. Fibre isn’t affected by inclement weather, moisture, or extremes of temperature to nearly the same extent that metal wiring can be - and the fact that glass fibers don’t carry a current means they don’t present a fire hazard even when damaged or aging.

Single mode vs multimode fiber optic cables

Single mode and multimode optical fibers are two distinct types of cable configurations that deliver differing potential levels of performance at distance.

In contrast to multimode cables, which are constructed around bigger cores that simultaneously guide many modes, single-mode fiber optic cables are built around a single strand of glass fiber with a relatively small diameter.

Single-mode fiber experiences significantly less internal reflection as light travels along it, which lowers attenuation and enables much faster data transmission over long distances. As a result of larger dispersion and attenuation rates and hence greater bandwidth delivery over shorter distances, multimode fiber cabling, in contrast, significantly increases the quantity of reflection.

Single mode is thus generally used for exceedingly long-distance signal transmission, while applications needing bigger amounts of data being sent over such a shorter run (such as communications data within either between relatively localized buildings) seem to use multimode fiber optic cabling.
