Abstract
An optical coupler (1) comprises two optical fibers (2, 3). Each of the optical fibers connects a sender unit (4) to a first end (9, 10). Then each of these fibers is connected independently to two independent receivers (6, 8). At the sender unit (4), the fibers are bared to be inserted into the same sleeve (15) which may be presented before the optical beam sent out by the sender unit. The bared intermediate zone between the sleeve and the non-bared cable portion is protected by a first sheath inside which the bared optical fibers are floating, and by a second protective sheath.
