A re-mateable 2D fiber interface. Instead of a permanently bonded array, the DFAU can be separated from and re-joined to its photonic counterpart — restoring sub-micron alignment on every mate cycle.
Permanent bonding has been the price of sub-micron alignment. The DFAU changes that: a precision registration system locates the array relative to its counterpart, so the interface can be mated and demated repeatedly without losing optical performance.
Detachability moves the 2D FAU from a one-time, factory-fused component to a serviceable field interface — a step change in how high-density optical connections are deployed, tested and maintained.
Replace or upgrade the fiber array without scrapping the optical engine — lower cost of failure and easier field repair.
A separable interface enables device- and system-level testing with clean re-mating between stages.
Field reconfiguration and easier maintenance in deployed systems, without de-committing the whole assembly.
Kinematic features locate the array in x, y and z relative to its counterpart.
Controlled contact brings the array into optical alignment and holds it under stable force.
The interface separates cleanly, protecting the optical face from damage and contamination.
Re-mate restores the same sub-micron alignment — cycle after cycle.
Holding sub-micron alignment across many mate cycles — the core engineering problem of any detachable high-density interface.
Mating surfaces must survive repeated contact and resist particulate contamination at the optical face.
Latched contact force must remain stable under temperature, vibration and long service life.
Registration and latching hardware must not consume the very pitch that detachability is meant to preserve.
