摘要
A structure for introducing an optical cable into a communication apparatus includes an adapter (3) to be affixed to a side wall (21) forming a part of the casing (2) of the apparatus. A case (4) is fitted in a bore axially extending throughout the center of the adapter (3). A ring nut assembly (5) holds an optical cable (6) at its center and is connected to the adapter (3) in such a manner as to cover the case (4). The cable (6) includes a tension merber (61) introduced into the casing (2) via the case (4) and adapter (3) and affixed by a tension member affixing portion (46) disposed in the casing (2). In this condition, the cable (6) is firmly affixed by the ring nut assembly (5) and tension member affixing portion (46), i.e., at two points. The fibers of the cable (6) are therefore free from breakage ascribable to a twisting force or a pulling force.
