At least a first portion of the bore extends along a longitudinal axis and is configured to receive the connector housing, and at least a second portion of the bore is configured to be radially spaced apart from the ferrule. The fiber optic dust cap also includes a transparent window positioned over the bore and configured to be longitudinally spaced apart from the ferrule when the connector housing is received by at least the first portion of the bore. A method of inspecting a ferrule end face through the dust cap is also disclosed. | 2021-03-18 |
20210080659 | CLEANING STICK GUIDE - A cleaning stick guide for an optical housing having ferrules therein. The cleaning stick guide includes a guide housing having a proximal end and a distal end. The guide housing includes an insert portion sized and shaped to be inserted into the optical housing. The insert portion defines the distal end of the guide housing. The guide housing includes guide passageways. Each guide passageway extends from the proximal end to the distal end. Each guide passageway is arranged in the guide housing to align with one of the ferrules in the optical housing when the guide housing is inserted into the optical housing. Each guide passageway is sized and shaped to receive a cleaning stick and to guide the cleaning stick to said one ferrule for cleaning the ferrule. | 2021-03-18 |
20210080660 | TELECOMMUNICATIONS CABINET WITH CONNECTOR STORAGE - A housing including a plurality of openings for receiving fiber optic connectors and protecting the polished end face of the connectors from damage while the connectors are stored within a telecommunications connection cabinet. A module with a plurality of optical fiber cables connected to a first optical fiber cable and terminated by a fiber optic connector. Each of the connectors are inserted within openings in a connector holder for storage and protection until the cables need to be connected to a customer equipment cable. | 2021-03-18 |
20210080661 | OPTICAL BLOCK WITH TEXTURED SURFACE - An optical block includes a first surface that receives light entering the optical block, a second surface through which the light exits the optical block, and a reflector that reflects light from the first surface towards the second surface. The reflector includes a textured surface that scatters or absorbs some of the light received from the first surface to attenuate the light exiting the optical block through the second surface. | 2021-03-18 |
20210080662 | ALIGNMENT FEATURES FOR FIBER TO CHIP ALIGNMENT - Embodiments herein describe an optical array unit configured to couple a photonic die with a plurality of optical fibers. The optical array unit includes alignment features which engage with alignment features on a corresponding photonic die. The engaged alignment features reduce the need for active alignment while also reducing the complexities of traditional passive alignment features. | 2021-03-18 |
20210080663 | ULTRA-SMALL FORM FACTOR OPTICAL CONNECTORS USED AS PART OF A RECONFIGURABLE OUTER HOUSING - An optical connector holding one or more optical ferrule assembly is provided. The optical connector includes an outer body, an inner front body accommodating the one or more optical ferrule assembly, ferrule springs for urging the optical ferrules towards a mating receptacle, and a back body for supporting the ferrule springs. The outer body and the inner front body are configured such that four optical ferrule assembly are accommodated in a small form-factor pluggable (SFP) transceiver footprint or eight optical ferrule assembly are accommodated in a quad small form-factor pluggable (QSFP) transceiver footprint. A receptacle can hold one or more connector inner bodies forming a single boot for all the optical fibers of the inner bodies. | 2021-03-18 |
20210080664 | OPTICAL INTERCONNECTS USING MICROLEDS - MicroLEDs may be used in providing intra-chip optical communications and/or inter-chip optical communications, for example within a multi-chip module or semiconductor package containing multiple integrated circuit semiconductor chips. In some embodiments the integrated circuit semiconductor chips may be distributed across different shelves in a rack. The optical interconnections may make use of optical couplings, for example in the form of lens(es) and/or mirrors. In some embodiments arrays of microLEDs and arrays of photodetectors are used in providing parallel links, which in some embodiments are duplex links. | 2021-03-18 |
