Abstract: The present disclosure relates to a ferrule boot that provides a pitch conversion from fiber ribbon having a first pitch (e.g., about 200 microns) to a multi-fiber ferrule having fiber openings arranged at a second pitch larger than the first pitch (e.g., about 250 microns). The ferrule boot may also function as a tool for inserting pitch converted optical fibers into the multi-fiber ferrule.

Abstract: An optical connector or a converter for an optical connector having a coupling nut such as a bayonet-style coupling nut. The optical connector or the optical converter are configured such that the coupling nut has a limited range of rotation defined between stop surfaces. The range of rotation can be less than 90 degrees. The stop surfaces can be provided by a guide slot defined by a first radial width portion and a second radial width portion.

Abstract: A coexistence module usable at secondary locations within a routing optical network is disclosed, which accommodates OTDR testing on the optical network without requiring a separate, dedicated fiber connected between secondary locations for such testing. Rather, a filter arrangement is used in which OTDR wavelengths are separated from transmission wavelengths and optically connected to bypass router equipment at the secondary location.

Abstract: One or more active components can be strand mounted within a cabinet that also has passive optical components. Certain types of strand mounts are slidable relative to the cabinet to enhance access to the components. Each component may be independently slidable.

Abstract: The present disclosure relates to a telecommunications connector. The connector includes at least one connector portion including a front housing portion coupled to a rear housing portion. The front housing portion defines a front end and a rear end, the front housing portion including a ferrule terminating a cable fixed to the at least one connector portion, the front housing portion further including a latch that is configured to contact a fiber optic adapter for locking the connector to the fiber optic adapter when the connector is inserted into the fiber optic adapter, wherein the latch is movable about a connection location on the front housing portion. The latch defines a permanently attached rear extension that extends rearward past the rear end of the front housing portion, the rear extension configured to be contacted for moving the latch for freeing the connector from the fiber optic adapter.

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.
