Methods for communicatively coupling components at down-hole locations within a wellbore include introducing first and second cables through which signals are transmissible into the wellbore. Terminal ends of the cables are coarsely aligned by coupling connector housings associated with the cables within the wellbore. The terminal ends are then finely aligned by activating motors to move at least one of the terminal ends within the connector housings until a signal of sufficient strength is transmissible between the first and second cables.

Provided herein are switching methods and systems for switching a patch cord fiber in a fiber management system having non-tensioned patch cord fibers, from a first adapter to a second adapter. Switching comprises disconnecting the patch cord fiber connector from the first adapter; distinguishing the disconnected patch cord fiber, at a region removed from the connector, from other patch cord fibers according to a position of the patch cord fiber in the fiber management system; pulling the distinguished patch cord fiber at the handling region to receive and clasp the disconnected connector, wherein the pulling is carried out to disentangle the pulled patch cord fiber from the other patch cord fibers; and connecting the clasped connector to the second adapter. The patch cord fibers are thus manages at edges thereof only, with no slack control required.

A passive optical fiber switch includes: a housing defining a plurality of ports configured to receive fiber optic connectors; a substrate positioned within the housing, the substrate defining a plurality of waveguide paths; and an arm positioned relative to one of the plurality of ports such that the arm moves as a fiber optic connector is positioned in the one port, movement of the arm causing the waveguide paths to shift to break a normal through configuration.

A fiber patch cord apparatus and a port panel, which may simplify a structure of the fiber patch cord system. The fiber patch cord apparatus includes a crawler configured to move to a corresponding position of a source adapter port along a crawling guide rail provided by a port panel, a clamper configured to clamp a fiber patch cord on the source adapter port, and a puller and inserter configured to pull the fiber patch cord out of the source adapter port and a controller that is configured to control the fiber patch cord apparatus to move on a crawling guide rail, where the controller is further configured to control a mold strip group on the port panel to move. The embodiments of the present invention are used to pull and insert a fiber patch cord.
