Adjacent each cassette (4) and inside the duct (1) there are storage means for receiving the cores (12), and advantageously constituted by drums (6) which are relatively displacable inside the duct in a vertical direction. The ducts also support, on their outside, three-way drums (22) associated with each cassette (4) and placed at the back of the cable head, and front drums (5) likewise associated with each cassette (4), said three-way drums (2) and front drums (5) serving to guide the jumpers (9). Each cassette (4) includes storage means for receiving the optical fibers (13) and advantageously constituted by drums (15). The various above-mentioned are each constituted by circular arcuate portions of radius approximately equal to the minimum radius of curvature appropriate the item wound around or guided by the drum in question, i.e. appropriate to cable cores (12), optical fibers (13), or jumpers (9), as the case may be.
