OTDR uses wavelengths of 1310 nm and 1550 nm to find fiber cut and fiber losses.

• OTDR (Optical Time Domain Reflectometer) is used to locate fiber cuts and measure fiber losses.

• OTDR sends a pulse of light into the fiber and measures the time and intensity of the reflected signal.

• 1310 nm wavelength is used for shorter distances and 1550 nm for longer distances.

• Fiber losses can also be measured using a light source and pow...read more

BOQ stands for Bill of Quantities. It is a document that lists all the materials, labor, and equipment needed for a construction project.

• BOQ is used to estimate the cost of a project.

• It helps in determining the quantities of materials required for a project.

• BOQ is prepared by a quantity surveyor or an estimator.

• It includes details such as item description, quantity, unit of measurement, and cost.

• BOQ is an important doc

TIR stands for Total Internal Reflection. It is a phenomenon where light is reflected back into a medium instead of being refracted out of it.

• TIR occurs when light travels from a medium with a higher refractive index to a medium with a lower refractive index at an angle greater than the critical angle.

• It is used in fiber optics to keep the light signal within the core of the fiber and prevent loss of signal.

• TIR is also...read more
