Abstract
Abstract An optical telephone wire comprising an optical conductor having a first covering of rectangular cross-section and a messenger cable having a second covering of rectangular cross-section with one set of sides of the two sets of parallel sides of the second covering being longer than one set of sides of the two sets of parallel sides of the first covering and with the first and second coverings being integrally juxtaposed along their longitudinal axes so that one side of the other set of parallel sides of each of the coverings forms together a common surface and one side of the one set of two sets of parallel sides of each of the coverings are offset from each other in a step like manner.

Claim 1
Independent Claim
185 words
An optical wire consisting of a single optical conductor (1), a single messenger cable (3), a first covering (2) for said optical conductor, and a second covering (4) for said messenger cable; wherein said first covering has a rectangular contour in section with a pair of parallel first sides of a first dimension and a pair of parallel second sides of a second dimension; said second covering has a rectangular contour in section with a pair of parallel third sides of a third dimension and a pair of parallel fourth sides of a fourth dimension; said first and second coverings being integrally juxtaposed along their longitudinal axes with a first side of the first covering being molded integrally to a third side of said second covering, with a second side of said first covering being in alignment with a fourth side of said second covering to form a common planar surface, and with the other second side of the first covering and the other fourth side of said second covering forming a step portion; and wherein said third dimension is longer than said first dimension.
