Fiber Optic Cable Parts

Fiber Optic Cable basically consists of several main parts, namely:

Core (core) - Core is the part that transmits light made of glass or plastic. The greater the core or core, the more light can be transmitted into the fiber.
Cladding - The outer optical part that surrounds the Core (core) which reflects light waves back to the Core.
Coating (Coating) - Coating is usually coated with plastic which is applied to maintain the strength of the fiber, absorb shocks and provide extra protection against Fiber. This buffer layer is available from 250 microns to 900 microns which serves to protect the fiber from damage and moisture.
Outer Jacket - Hundreds of up to thousands of fibers / optical fibers arranged and bundled in a fiber optic cable are protected by an outer cable wrapper which is usually called the outer jacket.

Types of Fiber Optic Cables
Optical Fiber Cables or Optical Fiber generally consists of two types, namely Single-mode fibers and Multi-mode fibers.

1. Single-mode Fiber (SMF)
Single-mode fibers are a type of optical fiber that is generally used to transmit longer distances. This Single Fiber Mode has a small core which is about 9 microns in diameter and sends out infrared laser beams that have wavelengths from 1,300 nanometers to 1,550 nanometers. Because it has a smaller diameter that allows only one mode of light to propagate, the amount of reflected light that is created when light passes through the core will decrease and can reduce attenuation thereby producing the ability for the signal to move further.

2. Multi-mode Fiber (MMF)
Multi-mode Fiber or Multi-mode Fiber is a type of optical fiber specifically designed to transmit more light rays at the same time with each of them at slightly different reflection angles in the optical fiber core. Multi-mode Fiber is generally used to transmit data over a relatively short range. Multi-mode Fiber has a larger core with a diameter of about 62.5 microns and transmits infrared light whose wavelengths are around 850nm to 1,300 nm from LEDs. Because it has a larger diameter, the amount of light reflected when the light passes through the core increases thus creating the ability to transmit more data at the same time.
