Abstract
Abstract A first embodiment of an optical splice having a frame with a channel; two rods each having a resilient exterior surface disposed in the channel; and a lid adapted to be received on the frame over the channel, the lid having a resilient surface adapted to allow compression of optical fibers placed end to end for splicing between the rods by the lid and the rods. The frame and lid are placed within a tubular housing and a tubular sleeve which is attached at the ends following insertion of the optical fibers. An additional embodiment of an optical splice contains first tube, a ferrule and an optical fiber, the optical fiber having first and second portions, the optical fiber first portion disposed inside of and affixed to the ferrule and the optical fiber second portion lying outside of the ferrule and inside of the first tube and a portion of the ferrule disposed inside of and affixed to the first tube; an alignment device and a second tube, both of which are disposed in the first tube; another optical fiber having a terminal end portion, the terminal end portion disposed in the second tube and said alignment device; and, a housing-coupling device affixed to the first tube, the housing-coupling device adapted to be removably coupled to a receiving device.
