Firstly, a fiber optic cable transmits light from one end of the fiber optic cable to the other end. You can kind of think of the fiber optic cable as a long tube. The way in which light travels from one end to the other is that it gets reflected off the inside parts of this glass or plastic tube by a physical phenomenon known as: Total Internal Reflection. Refraction of light only occurs when light travels from one medium to another. For example, when light travels from air to water, from water to air, from water to oil, etc. In other words, in terms of fiber optics, the only way light will get refracted is if it passes through the glass or plastic tube. But if this happened, then the light will exit the fiber optic cable as it travels from one end of the cable to the other end, and the light would not be properly transmitted, defeating the purpose of fiber optics. In other words, light should be reflective rather than refractive in fiber optics in order for light to be effectively transmitted from one end to the other end of a fiber optic cable.
Metalic conduit is a metal tube that is used to shield wiring from damage, water contamination, contact with people. As opposed to plastic conduit.
The water peak in fiber optics refers to a specific phenomenon where the attenuation of light increases significantly due to the presence of water molecules in the fiber's glass structure. This peak typically occurs around the wavelength of 1383 nm and results from the vibrational modes of the hydroxyl (OH) groups in the glass, which absorb certain wavelengths of light. As a result, fibers with high water content can experience increased losses at this wavelength, impacting the overall performance of optical communication systems. Minimizing water content during fiber manufacturing can help reduce the effects of the water peak.

Conduit diversion involves redirecting water flow from a natural stream or river into a man-made channel or conduit. This can be done for various purposes such as irrigation, hydroelectric power generation, or water supply for cities and towns. It is a common practice in water management to efficiently utilize the available water resources.
A water-filled trench around a castle is known as a "moat."
Its because of the water basically making there foot mouldy
The remedy for severe trench foot would be amputation or staying out of the water
I think that the 'trench' you are thinking of is a moat. You could say that it is a trench full of water that surrounds the castle. If you are not thinking of a moat then I am sorry.
No, they do NOT cause water retention. In fact, fiber diets have been shown to play a direct role in controlling water retention.
The best way to clean spirit optics is to use a soft, lint-free cloth with a little warm, soapy water to gently wipe the surfaces. Avoid using abrasive materials or harsh chemicals that could damage the optics. Dry the optics thoroughly after cleaning to prevent water spots.
