Abstract: The microbending is one of the passive processes that are undesired in the optical communication field. That is as it affects –during communication- in attenuating signal and noises the optical fibers. But it might be useful if it is well treated. This study treated the mechanical effects on due to microbending transmitted signal diode laser through an optical fiber, by using a communication system that contains: transmitter, receiver, an optical fiber, threaded aluminum blocks of different lengths and hydraulic pressure unit. Seven threaded aluminum blocks with different dimension and spatial periods are used to cause microbending. These blocks cross the ‫.‪the attenuation of the signal output and the effective pressure‬‬ ‫‪So the conclusion is that the mechanism of microbending can be‬‬ ‫‪used in optical fiber to produce a pressure sensor and this is done by‬‬ ‫‪measuring the attenuation of the signal output and then finding the value‬‬ ‫‪of the effective pressure on the optical fiber, which causes this‬‬ ‫.‪attenuation‬‬ ‫‪
