An articulated enclosure for an optical package comprises toro-spherical portions which form adjustable joints. Preferably the enclosure comprises two parts, each part comprising a cylindrical portion coupled to a toro-spherical portion. The toro-spherical portion includes several meridianal cuts to allow flexibility to the toro-spherical portions and permit one toro-spherical portion to overlap the other toro-spherical portion. Optical elements and subassemblies such as fiber ferrules and collimating lenses are affixed inside the cylindrical portions. The coupled toro-spherical portions form an adjustable joint which allows movement in three degrees of freedom and permits precision alignment of the internal optical components. The tension in the adjustable joint holds the alignment temporarily while the joint is secured with either solder or adhesive. The articulated enclosure permits optical alignment of the subassemblies and improved thermal protection.
