A spooled optical fibre data transmission line arrangement, for providing communication between a missile and a missile launcher, comprising a rigid, fluid-tight, hollow body (11) having first and second separable parts (13a, 13b), the optical fibre (15) being carried by one part (13a) and connected at one end via an opto-electric transducer (21) to a terminal means (17) extending through the wall (31a) of that one part, and the other end of the fibre being connected via a second opto-electric transducer (23) to a terminal means (19) extending through the wall of the other part (31b). The two separable parts suitably meet at a tear line (35) and tags (37a, 37b) extend from adjacent the tear line on one part to the other part to assist in complete rupture along the tear line when the fibre is required to be extended. |
