An optical fibre cable contains one or more strands of optical fibre that are used for digital communication. These cables transmit data signals in light over hundreds of kilometres to connect devices that may be needed to meet today's growing demand for data applications. Because optical fibre cables are non-metallic, they are immune to electromagnetic interference, which could reduce data transfer speed. Read More..
Be it data transfer requirements within four walls of an enterprise or accessing data from servers that reside in different continents, optical fibre cables is one of the most common means of data transmission across long distances. They are used to transmit light between the two ends of the fibre and are widely used in fibre optic communications. Optical fibre cables can support higher bandwidths and data transfer rates when compared with copper wires. This is the key reason for the popularity of optical fibre cables as long-distance data carriers of choice.
However, while optical fibre cable is most popularly known as a carrier of internet across continents, there are many areas beyond the internet where optical fibre cables have gained prominence. From cable television to military and even space applications, optical fibre cables are widely used across sectors for different applications.
There are two key types of optical fibre cable: single-mode and multimode. A single-mode optical fibre cable enables one kind of light mode to be propagated at a time. On the other hand, multimode optical fibre cable can propagate multiple modes. The two types are also differentiated by their respective fibre core diameters, wavelength and light source, bandwidth, colour sheath, distance and cost. Typically, single-mode optical fibre cable is used for long-distance transmission, while multimode optical fibre cable is more appropriate for short-distance transport of information.
Optical Fibre Cable transmits information at extremely high speed and is used in several applications in different industry verticals.
Apart from being used for research and testing purposes in several industries, Optical fibre cables are also widely used in surgeries and play a key part in endoscopy or non-intrusive surgeries. Other areas where optical fibre cable is used include safety applications like airbags, telephony, mechanical inspections and interior and exterior lighting in the vehicles.
A single-mode optical fibre cable can travel for a much longer distance with minimal loss when compared with multimode fibre cables. It is for this reason that they are primarily used for communication purposes. Single-mode fibre cable also has a much smaller core diameter of 5 to 9.5µ, while multimode optical fibre cable has a bigger core diameter of 100 to 970µ. A multimode optical fibre cable can support multiple light modes and is suitable for short to moderate distances. Typically, multimode optical fibre cables are nearly twice as expensive as single-mode fibre optical fibre cable.
Optical fibre cables can contain hundreds or even thousands of fibre strands that are put together and can transmit information for long distances even several hundreds of miles. Digital signals are converted into high-quality optical signals using an optical transmitter and sent at the speed of light for high-speed data transmission.
Optical fibre cables come in several variations, depending on the intended use and the manufacturer. Some optical fibre cables that are used for telephony are usually heavily sheathed to prevent any damage from harsh climatic conditions.
Similarly, a fibre optic patch cable often contains only two strands of fibre to allow it to be flexible enough that it can be wrapped around your hand. Each strand of an optical fibre cable can transmit in only one direction; two strands are required for full-duplex communication. In this type, two strands are merged in a covering or a jacket.
Optical fibre cable provides exceptionally high throughput making it the cable of choice for various use cases beyond just internet access. These cables have an extremely high resistance to noise, which eliminates interference and leakages of data. Optical fibre cables are also highly secure, and thus, it not surprising that they have become an industry standard for high-speed networking. Moreover, when it comes to carrying data for long distances, optical fibre cables can carry signals for much longer distances than traditional copper cables before requiring a repeater.
Optical fibre cables support ultra-fast data transfer rates that range between 10Mbps and 10Gbps in a regular cable but can go as fast as 100 Tbps. Each cable has multiple strands of fibre, essentially multiplying the amount of data that a single cable can carry by several times.
Ethernet cables, on the other hand, can go only as fast as up to 10Gpbs and to get the multiplier effect similar to optical fibre cable, you would require multiple Ethernet cables.
When it comes to security, optical fibre cables again turn out to be the superior choice as they offer much better protection for data in transit. Ethernet cables typically can be hacked very easily and quickly. Read Less..
