Optical Fibre Cable – Deconstructed

Optical Fibre Cables (OFCs) are used in many important telecommunication applications to transmit data. These cables are suitable for long-distance applications due to their wide bandwidth. They are also known for having high transmission rates against any form of electromagnetic interference (EMIs). Data in the form of optic monochromatic electro-waves can be transmitted with the aid of glass waveguides.

Selected Key Characteristics of an Optical Fibre Cable

Noise Resistance High Resistance to Noise

OFC is highly resistant to noise partially because of the construction, which includes a non-metallic glass cladding. Data is transmitted through the cladding using light pulse signals, which makes the cable immune to noise and increases the transmission rate.

Security Security

Unlike copper cable systems, OFCs can be installed in a central location and data is kept secure due to the high resistance to noise such as EMIs. This results in the least number of corrupted data packets lost in your network system.

 bandwidth-icon-5 Longer Bandwidth Distancing

OFCs have a longer bandwidth that allows information to be transmitted faster than networks of the highest speed using copper cables. As OFCs are made of mediums with a lower power usage rate during data transmission. OFCs can reach approximately 10km in bandwidth distance compared to the traditional 100m distance of copper cables.

Construction of an Optical Fibre Cable


No. Cable Part Description
1 Optical Fibres with Coating
  • A medium comprising of several strands made using glass or plastic to transport optical signals from a light source to the receiving application. 
  • These strands carry the light signals.
  • The coating protects the glass.
2 Loose Tube (Buffer)
  • Keeps the light in the core
  • Cannot be separated from the core
3 Binder Tape
  • Prevents penetration of water and moisture inside the cable
4 Central Strength Member
  • Provides tensile strength
5 Corrugated Steel Tape (CST)
  • Protects the inside of the fibres from possible mechanical stress caused by rodent and termite attacks
6 Outer Sheath
  • Reduces abrasion and provides extra protection against external mechanical effects
