Fiber optic energy storage power station working principle diagram

Why should a substation operator understand optical fiber design & specifications?

A good understanding of optical fiber design and specifications can help the substation operator design the fastest, most reliable links for their network.

What is the structure and properties of an optical fiber?

In this section, we discuss the structure and properties of an optical fiber, how it guides light, and how it is cabled for protection. Core: This central section, made of silica or doped silica, is the light transmitting region of the fiber. Cladding: This is the first layer around the core.

Why is optical fiber important for a substation?

Optical fiber provides the necessary electrical isolation to drastically reduce the risks to people and equipment. Substation operators make it their business to understand vital equipment such as switches and routers in order to specify and select the best product for their applications.

What is the light collecting capability of an optical fibre?

The light collecting capability of an optical fibre is directly proportional to its numerical aperture. The figure (numerical value) of merit which describes the light collecting ability of optical fibre is called its numerical aperture.

What are the components of a fiber optic link?

Simplistically, there are four main components in a fiber optic link (Figure 1). The transmitter converts the electrical signals to optical. A transmitter contains a light source such as a Light Emitting Diode (LED) or a Laser (Light Amplification by Stimulated Emission of Radiation) diode, or a Vertical Cavity Surface Emitting Laser (VCSEL).

How does optical fibre work?

When a ray of light is incident on the core of the optical fibre at a small angle, it suffers refraction and strikes the core-cladding interface. Due to the small diameter of the fibre, the angle of incidence is greater than the critical angle.
