<p>The present invention provides a connected optical cable capable of reinforcing a spliced portion of coated optical fibers to have adequate strength. The connected optical cable includes: a pair of optical fiber cables in which high-strength fibers are aligned in the longitudinal direction around coated optical fibers, the outer circumference of the coated optical fibers being covered by sheaths; and a connected portion in which the pair of optical fiber cables are connected, the coated optical fibers being extended from the sheaths, glass fibers exposed from the coating of the coated optical fibers being spliced to each other, and the connected portion being covered and formed into an integral unit, together with the high-strength fibers exposed from the sheaths, by a reinforcing tube placed over the optical fiber cables and caused to contract so that both ends of the reinforcing tube engage the sheath of the respective optical fiber cables.</p> |
