  • Publication number: 20200348475
    Abstract: An optical connector assembly (OCA) includes a connector housing to maintain alignment between optical components housed within the OCA and photoelectric converters on an optoelectronic substrate (OES) assembly. The optical components include a ferrule and an optical cable. The ferrule is optically coupled to the optical cable. The OCA includes a ferrule holder to hold the ferrule within the OCA, and a spring located between the connector housing and the ferrule holder. The spring is to apply a separating force between the ferrule holder and the connector housing. The OCA includes a gasket coupled to the connector housing. The coupling of the connector housing to a socket compresses the gasket to provide a seal between the connector housing and the socket.
