چکیده

Fiber optic cables are widely used in modern systems that must provide stable operation during exposure to changing environmental conditions. For example, a fiber optic cable on a satellite may have to reliably function over a temperature range of -50°C up to 125°C. While the system requirements for a particular application will dictate the exact method by which the fibers should be prepared, this work will examine multiple ruggedized fibers prepared in different fashions and subjected to thermal qualification testing. The data show that if properly conditioned the fiber cables can provide stable operation, but if done incorrectly, they will have large fluctuations in transmission.

Fiber - Optic Sensing of Linear Thermal Expansion (RESEARCH NOTES)

The use of a LED fiber-optic sensor to measure displacement and linear thermal expansion is described. It has a sensitivity of about 0.6 mV/mm, a resolution of 1.25 mm, and a dynamic rang of 400 mm for displacement measurements. For thermal expansion, it shows a sensitivity of about 3.5 mV/C, and the experimental linear expansion values are in agreement with those calculated. The reported senso...

Compensated Fiber-optic Frequency Distribution Equipment

One-way frequency distribution of atomic clock standards has been widely studied, and several architectures have emerged that employ the use of a return path signal to compensate for the effects of temperature and phase noise. These architectures have generally relied upon temperature-controlled delay lines to compensate for fiber thermal effects, and polarization scrambling techniques to minim...
