Fiber Optic Communication Sensitivity Experiment
We present a theoretical and experimental study in which we increased the sensitivity of a phase-sensitive optical time-domain reflectometer (phi-OTDR). This manual contains ten laboratory experiments to be performed by students taking the optical fiber communication course (EE 420). Much of data communications is concerned with sending digital information through systems that normally only pass analog signals. For such systems, modems are used to convert the digital signals into an analog form suitable for transmission. This study proposed an all-fiber Fabry–Perot interferometer (FPI) strain sensor with two miniature bubble cavities. The device was fabricated by writing two axial, mutually close short-line structures via femtosecond laser pulse illumination to induce a refractive index modified area in the core of.

How to calculate NA in fiber optic communication
The numerical aperture of an optical fiber is calculated using the refractive indices of the core ( (n_1)) and the cladding ( (n_2)): [ NA = sqrt {n_1^2 - n_2^2} ]The numerical aperture of an optical fiber is calculated using the refractive indices of the core ( (n_1)) and the cladding ( (n_2)): [ NA = sqrt {n_1^2 - n_2^2} ]In optics, the numerical aperture (NA) of an optical system is a dimensionless number that characterizes the range of angles over which the system can accept or emit light. By incorporating index of refraction in its definition, NA has the property that it is constant for a beam as it goes from one. an imaging system or an optical fiber) is a dimensionless measure of its angular acceptance of incoming light. Calculate numerical aperture, acceptance angle, light gathering capability, and modal characteristics for step-index and graded-index optical fibers in communication and sensing systems.
