Used FUJIKURA FSM-100P #293597905 for sale

FUJIKURA FSM-100P is an electronic test equipment used to verify the quality of optical fibers. It performs three main tests, including the insertion loss test, the return loss test, and the end-face geometry test. For the insertion loss test, it measures the amount of optical power that is lost when light travels through the fiber. This is done by comparing the power of incoming light to the power of the light leaving the fiber and calculating the difference. The result of the measurement is given in decibels (dB). The return loss test measures the amount of light that is reflected back when light is transmitted into the fiber. This is done by using the same technique as the insertion loss test, but measuring the reflected light instead of the transmitted light. The result is given in dB. The end-face geometry test measures the profile of the end face of a fiber, specifically the radius of curvature and apex offset. This information is used to determine the fiber quality, since a poor quality fiber would have a large radius of curvature and a large apex offset. FSM-100P uses a microscope to magnify the end face of the fiber and then a laser beam to measure the geometrical parameters. It then displays a result on the LCD display. Overall, FUJIKURA FSM-100P is a valuable tool for optical fiber quality testing. It is a precision instrument that accurately measures the insertion loss, return loss, and geometric parameters of a fiber. It is also relatively lightweight and easy to use, making it a great choice for both field and lab use.
