Abstract
An alignment coupler is provided to facilitate active alignment of the optical bench to the optical connector. The optical bench and the coupler together form an optical bench based connector. A method of demountable connection of an optical connector to an optical bench based connector, comprising: providing a coupler, wherein the coupler has an opening sized to receive an optical bench with clearance for relative movement between the optical bench and the coupler to facilitate alignment, and wherein the coupler is provided with a passive alignment structure structured to demountably couple to the connector; demountably coupling the coupler to the connector; placing the optical bench in the opening of the coupler; actively aligning the optical path between the optical bench and the connector to reach a desired optical alignment between the optical bench and the connector, by adjusting a position of the optical bench within the clearance of the opening of the coupler; fixing the position of the optical bench relative to the coupler at the desired optical alignment, whereby the optical bench is optically aligned to the connector using the coupler, thereby allowing subsequent demount…
