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.
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.
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.
In optical fiber propagation loss is increases or decreases with increase in length of the fiber cable?
Increases with length and connections.
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.
Does the gauge of fiber optical audio cable affect the audio quality?
No. As long as the signal is getting through, the gauge of the optical connection makes no difference.
What is meant by attenuation in optical fiber?
When an optical signal of a given wavelength travels in the fiber it looses power. The amount of loss of power per Km length of fiber is called its attenuation. A=10*LOG10(POUT/PIN) dB/Km Where POuT is optical power after 1 Km PIN is th epower launched in the Fiber.
