Abstract
We develop a cost-effective method for detecting flaws in large-core polymer optical fibers based on infrared thermometry. When the propagating light is 282 mW at 1.55 μm the temperature dependence of the optical loss at the flaw is linear with a proportionality constant of 0.74 dB/°C which can be enhanced using high-power light source.
