In an optical fiber monitoring system which detects physical disturbance or other parameters such as temperature or strain of a fiber where a monitor signal is transmitted along the optical fiber and analyzed to detect changes which are indicative of an event, a method is provided for periodically checking proper operation of the optical fiber monitoring system. A fiber disturbance actuator periodically causes a pattern of disturbances of a portion of the fiber at a predetermined location thereon where the disturbance is characteristic of the event to be monitored. The monitor signal is analyzed to detect the pattern of changes and in the event that expected changes are not detected, a warning is issued that the intrusion detection system is not properly operating.

A terminal for an optical fiber network includes a housing, a plurality of feeder cable adapters positioned in the housing, a plurality of distribution panel adapters positioned in the housing, and a bypass module positioned in the housing and including at least one bypass module adapter. A plurality of input optical fibers extend from at least one of the plurality of feeder cable adapters, into the main body of the bypass module, and to the at least one bypass module adapter. Additionally, a plurality of output optical fibers extend from the at least one bypass module adapter to at least one of the plurality of distribution panel adapters. The plurality of input optical fibers each optically couple to a single one of the plurality of output optical fibers within the at least one bypass module adapter.

A protective apparatus for telecommunication lines includes a mounting frame, a transition platform coupled to the mounting frame, and a protective skirt that is coupleable to the mounting frame. The mounting frame includes at least one sidewall having a sidewall opening to allow passage of a telecommunication line. The transition platform includes an opening to allow passage of the telecommunication line to an adjacent telecommunications terminal. The protective skirt includes a cutout corresponding in shape to the sidewall. The mounting frame, the transition platform and the protective skirt define an internal space when the protective skirt is coupled to the mounting frame. The telecommunications lines enter and exit the internal space by passing through the openings in the sidewalls, thus permitting removal of the protective skirt without the need to remove some or all of the telecommunications lines from the mounting frame or the telecommunications terminal.

A pre-mounted fiber optic distribution cabinet assembly is disclosed. The pre-mounted fiber optic distribution cabinet assembly includes a fiber optic distribution cabinet with an enclosure having an interior configured to house fiber optic components. The fiber optic distribution cabinet is sealed to protect against the ingress of solid foreign objects and liquids into the interior. A frame attaches to the exterior of the enclosure so that the fiber optic distribution cabinet is mounted in the frame when shipped to an installation location. The fiber optic distribution cabinet is configured to be mounted at the installation location via the frame. A stabilizer attached to the fiber optic distribution cabinet provides balancing support to the fiber optic distribution cabinet to maintain the fiber optic distribution cabinet in a generally upright orientation with the frame attached to the fiber optic distribution cabinet.

A secure cable housing system for use within a secure fiber optic communications network is provided. The secure cable housing system includes a non-secure cable box and a secure equipment box. The secure network equipment box includes a secure interior cavity, and the non-secure cable box is smaller than the secure interior cavity such that the non-secure cable box fits within the secure interior cavity. The secure network equipment box allows the optical cable to be received into the secure interior cavity without disconnecting the fiber optic cable from the non-secure box.
