Steam-resistant cable such as steam-resistant optical fiber cable.

摘要

A steam-resistant optical fiber cable (20) includes a core (21) comprising a plurality of optical fiber ribbons (22,22) disposed within a tubular member (30) comprised of a high temperature resistant material. The tubular member is disposed within a hermetic sealing member (40) which comprises a metal of low electrochemical activity having a sealed seam. An outer jacket (50) is disposed about the hermetic sealing member and in a preferred embodiment is characterized by resistance to degradation in high temperature, high humidity steam environments. The core may be unfilled or filled with a waterblocking material and in a preferred embodiment, a waterblocking member is interposed between the tubular member and the hermetic sealing member. <IMAGE>
