Loss measurements in optical fibers. 2: bolometric measuring instrumentation.
This paper describes two approaches to measuring transmission losses in optical fibers by the thermal-rise technique. Rapid and convenient loss determinations can be made on short (~10-cm) lengths of fibers. Values of loss as low as ~10(-7) cm(-1) (0.043 dB/km) can be measured with transmitted light power of ~100mW.
