An optical assembly includes first (102) and second (103) housings configured to move relative to each other. The first housing includes an attachment area (124) configured to permanently attach an optical waveguide (122) and having a facet (634) that optically couples the optical waveguide to the first housing. The first housing further includes an first input/output surface (112) at a non-zero angle to the facet and a light redirecting member (638) optically coupled to change a direction and divergence of light between the facet and the first input/output surface. The second housing includes a second input/output surface (113) facing and optically coupled to the first input/output surface. The first and second input/output surfaces maintain an alignment along a light propagation direction therebetween through a range of motion between the first and second housings. The second housing includes a transmission path configured to convey signals optically received or transmitted via the second input/output surface.
