Abstract
Abstract The invention relates to a system for field restoration of severed fiber optic cables containing multiple optical fiber conductors therein. The system includes two hermetically sealable restoration connector containers having lids to permit access to the interior thereof. The containers are interconnected by at least one fiber optic cable containing multiple optical fibers extending therein with each fiber of the cable terminated by respective fiber optic connectors which are mounted on adapters in a panel in the respective containers for interconnection to temporary connectors used in field restoration. A plurality of temporary connectors are arranged within the respective containers and each container includes a hermetically sealable opening for passing a severed cable with the fiber ends extending therefrom into the container or by the individual fibers can be rapidly terminated by the temporary connectors and the ends projecting from the temporary connectors flush cleave with the end face thereof. The temporary connectors can then be interconnected to the adapters on the panel to is corresponding permanent connector and fiber connecting to the other restoration container.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
162 words
A fiber optic cable restoration system for restoring severed fiber optic cables, comprising: at least two hermetically sealable restoration connector containers having lids to permit access to the interiors thereof; said containers interconnected by at least one fiber optic cable containing multiple optical fibers extending therein; each fiber of said cable terminated by a respective fiber optic connector, with each of said connectors mounted connected to adapters mounted on a panel in said respective containers for connection to compatible respective connectors through the adapters; cable attachment means arranged on each container for passing the end of a severed fiber optic cable into each one of said containers and attaching the severed cable in a hermetically sealed manner to the respective connector; and a plurality of temporary fiber terminating connectors, corresponding to the number of fibers in the respective severed cable for terminating the respective severed fibers and for connecting the thus terminated fibers to the connectors and fibers mounted on said panel.
Claim 2
Dependent Claim
162 words
A fiber optic cable restoration system for restoring severed fiber optic cables, comprising: at least two hermetically sealable restoration connector containers having lids to permit access to the interiors thereof; said containers interconnected by at least one fiber optic cable containing multiple optical fibers extending therein; each fiber of said cable terminated by a respective fiber optic connector, with each of said connectors mounted connected to adapters mounted on a panel in said respective containers for connection to compatible respective connectors through the adapters; cable attachment means arranged on each container for passing the end of a severed fiber optic cable into each one of said containers and attaching the severed cable in a hermetically sealed manner to the respective connector; and a plurality of temporary fiber terminating connectors, corresponding to the number of fibers in the respective severed cable for terminating the respective severed fibers and for connecting the thus terminated fibers to the connectors and fibers mounted on said panel.
Claim 3
Dependent Claim
25 words
A system as in claim 1 further comprising cleaning means for ensuring that fibers terminated by said temporary connectors are clean at the ends thereof.
Claim 4
Dependent Claim
31 words
A system as in claim 1 further comprising cleave tool means for cleaving the ends of fibers terminated by said temporary connectors in a manner flush with the end faces thereof.
Claim 5
Dependent Claim
24 words
A system as in claim 2 wherein said cleaning means comprises a container of cleaning liquid, a container of compressed air and sanitized wipes.
Claim 6
Dependent Claim
12 words
A system as in claim 4 wherein said cleaning liquid is methanol.
Claim 7
Dependent Claim
204 words
A system as in claim 1 wherein said temporary connectors comprise respectively: a ceramic plug having a front end and a rear end, a passageway extending through said plug with said passageway sized to snugly receive a buffer stripped optical fiber therethrough in a manner extending out the front end, and said passageway having a size proximate the rear end such as to permit a portion of buffer covered optical fiber to be received therein; a plug support supporting the rear end of the ceramic plug, and said plug support having a passageway coextensive with said plug passageway, and having biasing wall surfaces in said support passageway at a location proximate to the rear end of said ceramic plug; and chuck means having clamping means for holding a fiber, said chuck means having a passageway extending therethrough coextensively with the plug support passageway whereby an optical fiber can be passed from the rear thereof therethrough into said ceramic plug to extend from the front end of said ceramic plug, said chuck means engageable to said plug support in a manner such that said biasing wall surfaces engage said clamping means to cause said clamping means to securely seize a buffer covered fiber received therein.
Claim 8
Dependent Claim
30 words
A system as in claim 6 further comprising cleave tool means for cleaving the ends of fibers terminated by said temporary connector flush with the front end of said plug.
Claim 9
Dependent Claim
73 words
A system as in claim 7 wherein said tool means comprises means for receiving the temporary fiber optic connector with the front end of a fiber mounted therein extending from the front thereof; means for scoring the fiber at a point flush with the end of the plug; and means for applying a separation force to said fiber along the axis thereof to cause a separation of the fiber at the scored portion.
