Fiber Optic Cable

Fiber optic cable is a network cable. This cable is based on fiber optics technique. As you know, the transmission across cable is done via electrical signals. However, the transmission across fiber optic cable is done in a distinct way. Primarily, the electrical signals are commuted in optical signals. After that, these optical signals are conveyed through a narrow glass fiber strand, and then reformed in electrical form. A fiber optic cable is made up of glass or plastic, and the signal propagates in the form of light. The inner core is surrounded by a cladding of glass or plastic that is less dense than the core. These cables have a higher bandwidth and are also thinner and lighter than the metallic cables. Because of the higher bandwidth, fiber optic cables can carry more data. The main disadvantage of this type of cable is that it is quite expensive to install. A fiber optic cable is used as a transmission medium in the Ethernet media systems, such as Fiber Optic Inter-Repeater Link (FOIRL), 10BaseFL, 10BaseFP, 100BaseFX, 1000BaseLX, and 1000BaseSX.

Fiber Optic cables are classified into two primary types as follows:

  • Single-Mode Fiber (SMF)
  • Multi- Mode Fiber (MMF)
