Fiber Optic Cables - In Computer Networking

EP. 04 |  What  is  OSI MODEL ?


Fiber Optic Cables:-

Fiber optic cable is a fast information transmission medium. Fiber optic cables carry communication signals using pulses of light generated by small lasers or light-emitting diodes (LEDs).

It contains minor glass or plastic fibers, which carry light beams and the coating helps preserve the fibers from heat, cold, electromagnetic delay from distinct types of wiring, as readily as some protection from ultraviolet rays from the sun. 

Fiber optics manages for an essentially faster data transmission than standard copper wires.  And the fiber optic cables bandwidth is much higher than other cables.

Advantages of Fiber optic Cables

  1. Fiber cables offer several advantages over traditional long-distance copper cabling.
  2. Fiber optics have a higher capacity. The amount of network bandwidth a fiber cable can carry easily exceeds that of a copper cable with similar thickness. Fiber cables rated at 10 Gbps, 40 Gbps and even 100 Gbps are standard. Since light can travel much longer distances down a fiber cable without losing its strength, it lessons the need for signal boosters.
  3. Fiber is less susceptible to Interface. A traditional network cable requires special shielding ( like in STP ) to protect it from electromagnetic interference when many cables are strung together in close proximity to each other. The physical properties of glass and fiber cables avoid most of these issues.
There are two types of Fiber optic cables they are:
  1. Single mode Fiber Optic Cable
  2. Multi-mode Fiber Optic cable
The table below describes the differences between single mode and multi-mode fiber optic cables.
