Abstract

A high-density optical connector for demountable coupling to an external component is provided. The optical connector includes a fiber block including a front surface, a back surface and passages extending from the back surface towards the front surface. Each passage is configured to receive an optical fiber. A carrier is attached to the front surface of the fiber block, including a plurality of elastic averaging features spaced apart from each other. The carrier includes a plurality of first lenslets arranged in a first planar array. The elastic averaging features are arranged in a second planar array interspersed among the first lenslets.
