Why Is Fiber Optic Cable More Secure and Reliable?
Fiber optic cable is more secure and reliable compared to traditional copper cables for the following reasons:
- Immunity to electromagnetic interference: Fiber optic cables use light signals to transmit data instead of electrical signals, making them immune to electromagnetic interference from sources like power lines, radio frequencies, or nearby cables. This immunity enhances the reliability of data transmission and reduces the risk of signal degradation or loss.
- Difficult to tap or intercept: Fiber optic cables are difficult to tap or intercept without causing noticeable signal loss. Unlike copper cables that can be easily tapped by attaching monitoring devices, fiber optic cables do not emit detectable electrical signals, making them more secure against unauthorized access or eavesdropping.
- Long-distance signal transmission without degradation: Fiber optic cables can transmit data over much longer distances without significant signal degradation compared to copper cables. This allows for more reliable communication over extended distances without the need for signal boosters or repeaters, resulting in a more robust and dependable network.
What are the problems faced in optical fibre communication?
The problems faced in optical fiber communication include signal attenuation (loss of signal strength over distance), dispersion (spreading out or distortion of light signals), and nonlinear effects that can distort the transmitted signal and limit data transmission quality. Another problem faced in optical fiber communication is vulnerability to physical damage. Optical fibers, being thin and delicate, can be easily damaged by factors such as bending, twisting, crushing, or accidental cuts. These physical damages can disrupt signal transmission and require costly repairs or replacement of the affected fiber sections.

What is used to block light in optical fibre communication?
In optical fiber communication, a cladding layer is used to block or confine the light within the fiber core. The cladding layer, typically made of a material with a lower refractive index than the core, surrounds the core and ensures that the light propagates through total internal reflection. This prevents the light from escaping the fiber and helps maintain signal integrity throughout the transmission.
