  • Patent number: 12663842
    Abstract: A bladed chassis system facilitates installation of the bladed chassis system and replacement of the blades at the chassis. Blades can be inserted and removed from the front and/or the rear of the bladed chassis system at the discretion of the user. Blades can be moved between discrete positions. In examples, blades can be one-handedly released from the chassis to allow movement between discrete positions. In examples, accidental movement past a discrete position is inhibited. Accidental removal of the blades from the chassis is inhibited. The chassis and blades cooperate to manage the optical fiber cables routed through a cable port in the chassis to the blades.

  • Patent number: 12287519
    Abstract: A flexible optical fiber connector comprises a first housing component configured to couple to a terminating connector, and a second housing component configured to receive an optical fiber for termination in the terminating connector. The first housing component and the second housing component are further configured to receive a pushable connector therethrough. A flexible optical fiber connector assembly comprises a flexible connector and a terminating connector coupled thereto. The flexible connector assembly is configured to couple to an adapter held by a holder coupled to a port.

  • Patent number: 11860433
    Abstract: An optical module includes a housing; an optical adapter arrangement disposed at the housing; a cable inlet leading from an exterior of the housing to the interior of the housing; and a splice location disposed within the interior of the housing. Optical pigtails extend from the optical adapter arrangement to the splice location. Certain types of modules have a removable splice tray having a bend radius limiting arrangement surrounding multiple splice channels. Certain types of modules have first and second chambers separated by a wall defining a pass-through aperture.
