B.S.T.J. Brief: Effect of ambient temperature on infrared transmission through a glass fiber

Recent progress in reducing the losses in optical fibers
¹
has increased the possibility that such fibers might be used as dielectric waveguides in future optical communication systems.
²
The loss properties of such fibers are therefore of interest. This note concerns the measured change in transmission loss of a glass fiber for an ambient temperature variation of −196°C to +200°C. The results indicate that the loss in glass fibers varies only slightly with temperature.
