1. A protective distribution system with alarmed, interlocking armored fiber optic cables, comprising:
- a distribution panel in a secured location, at least a first interlocking armored fiber optic cable connected to the distribution and carrying a fiber optic outgoing alarm line and fiber optic return alarm line to transmit alarm signals, and least one data line that is not connected to encryption devices or software and transmitting data that is not encrypted;
a secured junction box connected to the first fiber optic cable and having a plurality of interlocking armored, outgoing fiber optic cables each connected to the junction box at one end of each cable and connected to a different secured user lock box at the other end of the each cable so as to transmit data through the outgoing fiber optic cables;
at least a selected group of the plurality of outgoing fiber optic cables each having a fiber optic data transfer line transmitting the non-encrypted data, and in addition the fiber optic outgoing alarm line and fiber optic return alarm line to transmit alarm signals, the selected group containing at least a first cable with a first outgoing alarm line and a first return alarm line and a last cable having a last outgoing alarm line and a last return alarm line;
a jumper in each user lock box that is connected to the selected group of fiber optic cables, the jumper looping the outgoing alarm line to the return alarm line contained within the same cable connected to that user lock box so an alarm signal can pass from the outgoing line to the return line;
at least one jumper in the secured junction box connecting the return alarm line of the first cable within the selected group to the outgoing alarm line of another cable within the selected group to form a continuous fiber optic path of connected alarm lines through the secured user boxes associated with the first cable and said another cable until the last return alarm line is in fiber optic communication with the first outgoing alarm line; and
a detector in communication with the least the return alarm line which is in fiber optic communication with the return alarm line at the distribution panel, the detector configured to detect an alarm signal in the continuous fiber optic path of connected alarm lines.

Abstract
A fiber optic network has alarmed fiber optic lines in the cables connecting a secured junction box to plural user lock boxes. An outgoing alarm line and return alarm line in each cable connect the junction box to each user box. The outgoing alarm line is looped to the return alarm line inside the user lock box. The return alarm line is looped to the outgoing alarm line of a different cable inside the junction box to interconnect a plurality of alarm lines passing through a plurality of user boxes. A detector detects an alarm signal in the connected alarm lines to trigger an intrusion alarm.

12. A method for alarming interlocking armored fiber optic cables in a protective distribution system having a fiber optic distribution panel in fiber optic communication with at least one secured junction box through an interlocking armored fiber optic cable, the junction box having at least one interlocking armored fiber optic input cable and further having a plurality of outgoing interlocking armored fiber optic cables each connected to the junction box and each connected to a different secured user lock box to transmit data through the fiber optic cables, comprising:
-
providing at least a selected group of the plurality of cables each having an optical fiber data transfer line, and further having a fiber optic outgoing alarm line and a fiber optic return alarm line to transmit alarm signals within each of the selected group of cables; within each user lock box connected to the selected group of cables, looping the outgoing alarm line to the return alarm line contained within the same cable connected to that user lock box; forming a continuous fiber optic path of connected alarm lines by connecting the return alarm line of a first cable within the selected group to the outgoing alarm line of another cable within the selected group, the connecting occurring within the secure junction box, and also connecting the outgoing alarm line to the return alarm line within the secure user lock box connected to the cable carrying both the outgoing and return alarm lines that are joined in the secure user lock box; and connecting at least the return alarm line from a last one of the selected group of cables to a detector to detect an alarm signal in the continuous fiber optic path of connected alarm lines. - View Dependent Claims (13, 14, 15)

18. A fiber optic network having at least one secured junction box and a plurality of secured user boxes each connected to the junction box by a different interlocking armored fiber optic cable, the network comprising:
-
a selected plurality of the fiber optic cables including at least a first cable connected to both the junction box and a first secured user box and including a last cable connected to both the junction box and a last secured user box, each of the selected plurality of cables including an outgoing fiber optic alarm line, a return fiber optic alarm line and at least one fiber optic data line; the selected plurality of the fiber optic cables further having the outgoing line being looped to connect to the return line within the secured user box that is connected to the cable such that the outgoing alarm line of the first cable connects to the return alarm line of the first cable within the first secured user box and the outgoing alarm line of the last cable connects to the return alarm line of the last cable within the last secured user box; the selected plurality of fiber optic cables further having the return alarm line connected to the outgoing line of another cable within the selected plurality of fiber optic cables, within the secured junction box, such that the return alarm line of the first cable connects to the outgoing alarm line of another cable within the selected plurality of fiber optic cables to form an interconnected fiber optic alarm line extending through the selected plurality of fiber optic cables and the user boxes associated with the selected plurality of fiber optic cables from the first cable and first user box to the last cable and last user box; and a detector in communication with the last return alarm line configured to send a signal to the outgoing alarm line and to detect an alarm signal in the last return alarm line.
