Abstract
Fiber optic cables suitable for use in nuclear radiation environments are disclosed which comprise a protective shield of low absorptance material which reflects thermal radiation. The shield is composed of layers of aluminum and Teflon.
Claims3
A fiber optic cable capable of withstanding a nuclear radiation environment comprising:
- at least one optical fiber;
- a strength layer adjacent to said optical fiber;
- a first thermal radiation reflecting layer, comprising aluminum foil, adjacent to said strength layer, to reflect incident thermal radiation from said nuclear radiation environment;
- and
- a second thermal reflecting layer, comprising a white fluoropolymer, adjacent to said first thermal reflecting layer, to reflect incident thermal radiation from said nuclear radiation environment.
