<p>A splice between ends of a pair of telecommunications cables is encapsulated in a thermoset foam. To encapsulate the splice it is positioned within a mold with the cables extending through apertures in the mold. At the apertures the cables are wrapped with an open cell foam material to block the cavity ends. Chemical reagents which undergo a foaming reaction, before solidifying, are then mixed, the mixture is deposited within the mold, and the mold closed. The mixture them foams to fill the mold with a closed cell foam which rapidly cures. The resulting joint is light, durable, waterproof and can be made re-enterable.</p> |
