You have to further clarify your question - it's too broad.
Signal strength can be increased during each of these phases of the OF's life:
* either during the design phase,
* during manufacturing using special manufacturing techniques, and
* during final installation and usage.
For each of these, the answer is very complex.
Also say if you are looking for a general (lay person's) explanation or a detailed (optics, physics) explanation.

What is different between optical fiber signal and electrical signal?
A fiber optical signal is based on the transfer of photons, while an electrical signal is based on the transfer of electrons.
What type of waves carry optical fibre signals?
Light waves carry optical fiber signals. These waves are typically in the infrared range and are able to travel long distances through the fiber without losing signal strength.
What optical fiber used for?
Long Distance signal transmission!
What is meant by atenuation in fiber optics?
Attenuation in fiber means 'loss of optical power' suffered by the optical signal in fiber itself.
What does negative loss means in optical fiber tests?
In optical fiber tests, a negative loss indicates that the received optical power is greater than the transmitted optical power, which is typically not expected under normal conditions. This can occur due to factors like amplifier gain or reflections enhancing the signal strength at the receiving end. Negative loss may suggest measurement errors, equipment issues, or the presence of additional components that amplify the signal. It's essential to investigate the cause, as it can lead to misinterpretation of the fiber's performance.
Can you propagate optical signal over electrical network?
only over fiber
How a scratch outside of an optical fiber might cause problems?
Fiber optics, using optical fiber, are specially designed to implement total internal reflection. A signal passed from one end of the fiber to the other end of the fiber is a single beam of light that repeatedly bounces off the edges of the fiber until it reaches it's destination. By scratching the outside of an optical fiber, this property can be disrupted causing the signal to be lost.
What is edfa and where is it used?
An Erbium-Doped Fiber Amplifier (EDFA) is a type of optical amplifier that utilizes erbium-doped fiber to amplify light signals in fiber optic communications. It is primarily used in long-distance telecommunications to boost signal strength without the need for converting the optical signal to an electrical one, thereby maintaining higher data transmission rates and reducing signal loss. EDFAs are essential in modern optical networks, enabling efficient data transfer over vast distances, such as in undersea cables and metropolitan area networks.
Is optical fiber ihollow or not?
The main part of an optical fiber is a glass fiber (NOT hollow) within another glass fiber of another type of glass. Both types of glass have a different index of refraction; the signal travels through the inner glass fiber.
What happens to light rays as they travel along an optical fiber?
Light rays traveling along an optical fiber undergo total internal reflection at the core-cladding interface, which helps contain the light within the core. This allows the light to travel long distances without significant loss of signal strength.
What are the important blocks of point to point links in optical communication.?
In optical communication, important blocks of point-to-point links include the light source (typically a laser), which generates the optical signal; the optical fiber, which transmits the signal over distances; and the photodetector, which converts the received optical signal back into electrical form. Additional components may include amplifiers to boost signal strength, multiplexers and demultiplexers for combining and separating multiple signals, and various types of connectors and splices for ensuring effective signal transmission. These elements work together to ensure efficient and reliable communication over optical networks.
In optical fiber propagation loss is increases or decreases with increase in length of the fiber cable?
Increases with length and connections.
