Embodiment Construction

[0027] Embodiments described herein relate to optical connectors and connector systems that mitigate the ingress of dirt into connector housings. Optical connectors may be used to connect optical waveguides to optical waveguides or to optoelectronic components for in-line interconnects and / or printed circuit board (PCB) connections, such as backplane connections. Optical connectors used in many applications may utilize one waveguide or an array of multiple parallel waveguides (typically 4, 8 or 12 or more parallel waveguides). The individual waveguides are usually made of glass with a protective buffer coating, and the parallel waveguides are enclosed by a jacket.

[0028]One type of connector is an expanded beam connector, in which light is coupled between waveguides in a beam of diameter larger than the diameter of the core of the associated optical waveguide and typically slightly smaller than the waveguide-to-waveguide spacing. The waveguide may comprise optical fiber, su...

Abstract

An optical connector (100) is provided and includes a housing (112) configured to contain one or more optical ferrules (121) disposed within the housing and accessible through an opening at a mating end of the housing. A cover (130) is disposed at the mating end, the cover being configured to be rotated about a pivoting axis between a closed position and an open position. An actuator (135, 136) isconfigured to cause the cover to rotate about the pivoting axis from the closed position to the open position.

Description

technical field [0001] The present disclosure generally relates to optical connectors and systems thereof. Background technique [0002] Optical connectors are used for optical communications in a variety of applications including: telecommunications networks, local area networks, data center links, and internal links in computer equipment. There is interest in extending optical communications to applications inside small consumer electronic devices such as laptops and even cell phones. Expanded beams can be used in connectors for these systems to provide an optical connection that allows for relaxed alignment tolerances. However, the ingress of dust into the connector housing can introduce angular errors in the expanded beam and / or other optical interconnects, which lead to suboptimal operation. Contents of the invention [0003] Embodiments relate to an optical connector that includes a housing configured to receive one or more optical ferrules disposed within the hous...
