An optical device has outer walls 35,45 with which one ore more optic fibres 30,40 are routed. A flexible strengthening member 50 is attached to the optic fibre 40 adjacent an outer aspect of the wall 45 and guide formations 60 protrude from the wall 45, being positioned and shaped with respect to the strengthening member 50 to prevent the strengthening member 50 from bending in at least one direction at a predetermined bend radius. The guide formations 60 can be disposed on at least two opposing sides of the strengthening member 50, and can form a opening which narrows towards the wall. The guide formations 60 may also be curved where the curve radius is greater than or equal to the predetermined minimum radius to prevent optic fibre strain, the guide formations 60 may also be circular symmetric. |
