What is Fiber Optic Cable?

Fiber optic cable is a type of cable that uses light instead of electrical energy. Its components and applications are very similar to those of an electrical cable, but instead of carrying electrical energy, it carries light. Read on to learn more about fiber optic cable and how it works. You can also learn more about its cost and applications.


Fiber optic cables have three basic components: the fiber core, the cladding, and the strength members. In addition, some cables contain a copper conductor to provide power to the fiber. The core and cladding are made of glass, but some are made of plastic. The three parts work together to send light from one device to another.

The separation layer prevents water from entering the cable. This separation layer is usually located within the cable jacket 50. A ripcord 54 facilitates removal of the cable jacket. The fiber optic cable may also be used as an interconnect cable. Generally, the cable jacket is round. It may have a number of layers, including a ring-shaped separator.

The optical fibers in fiber optic cable 40 are bundled into bundles of at least twelve. The fibers can be of different colors. The inner bundles may be stranded or unstranded, but are otherwise not twisted together. The fibers are also protected by a cable jacket, which is typically made of plastic.


Fiber optic cables are a great way to communicate across long distances at high speed. They are ideal for situations where wired cables are inconvenient or are not available. They also offer speed, reliability, and security. Many industries rely on fiber optic cables to connect buildings and systems. Listed below are a few of their applications.

Optical fibers are used in the transmission of data and video signals. Their light signals are not affected by other fibers in the same cable, leading to clearer TV reception and telephone conversations. Optical fibers also have a very long lifespan compared to copper wires. They are also more fragile and easily damaged than copper wires, which means they need to be properly maintained.

Another application for fiber optics is in the medical field. It can serve as an imaging tool or laser for surgeries. In addition to medical uses, fiber optic cables can be used to light Christmas trees and other holiday displays. These cables are also ideal for inspecting pipes and hard-to-reach places.


Fiber optic cable installation can be expensive, ranging from $1 to $6 per linear foot, depending on the length and number of fibers used. The installation of a 100 to 200-drop network can cost anywhere from $15,000 to $30,000. While fiber optic cabling is more expensive than copper cabling, it offers greater capacity and reliability. You can find cost information on the U.S. Department of Transportation’s website.

The cost of singlemode fiber is less than that of multimode fiber. The singlemode variety eliminates the effects of modal dispersion and can support higher bandwidth levels. The singlemode variety is suitable for long-haul signal transmission applications. Since there are no limitations on the length of singlemode fiber, the cost of installing a singlemode installation is much lower than that of a multimode installation.

Another significant benefit of fiber optic cable is that it is safe to handle. Since fiber cables do not contain metallic components, they do not experience changes in temperature or humidity. This means that they can handle harsh conditions without compromising their performance.
