Positioning device and alignment fixture for linear optical fiber array

A fixture for holding and aligning a linear array of optical fiber terminators, comprising:

• a base;
• a bracket coupled to the base and extending from the base in a heightwise direction, the bracket including a lengthwise wall oriented along a lengthwise direction;
• a heightwise stack of positioning devices disposed on the base, each positioning device including:
• an anchor secured to the lengthwise wall;
• a terminator holder flexibly coupled to the anchor and having a lengthwise channel for holding a respective optical fiber terminator, the terminator holder having two planar surfaces orthogonal to the heightwise direction, respectively, the two planar surfaces defining a heightwise extent of the terminator holder and interfacing with the terminator holder of any adjacent positioning device of the stack, and
• a plurality of actuators cooperatively configured to control in-plane position and yaw of the terminator holder in a first plane orthogonal to the heightwise direction;
• and
• a clamp for clamping the positioning devices against each other and clamping the stack against the base after setting the in-plane position and yaw of each terminator holder using the respective actuators.
