Claim 3

An optical fiber distribution frame according to claim 1 wherein said adaptors are provided with means for holding said plurality of fibers at a predetermined angle to said panel with said angle selected to be less than 90°.

Claim 4

An optical fiber distribution frame according to claim 2 wherein said connector cabinet includes openings disposed along forward side edges of said cabinet for fibers to pass through said side edges to said adaptors.

Claim 5

An optical fiber distribution frame according to claim 1 wherein a predetermined back surface of said frame member includes a plurality of fiber guides with opposing surfaces of said guides defining cable pathways and with said opposing surfaces rounded to have a radius of curvature not less than a predetermined minimum radius of curvature to prevent damage to optical fibers.

Claim 6

An optical fiber distribution frame according to claim 1 wherein said splice cabinet includes means for admitting optical fibers through a rear wall of said cabinet, said rear wall including means for controlling a radius of fiber entering said cabinet.

Claim 7

An optical fiber distribution frame according to claim 5 wherein said splice cabinet includes a plurality of trays, each of said trays including a splice fixture mounted within said tray for receiving and retaining optical fibers in predetermined alignment.

Claim 8

An optical fiber distribution frame according to claim 2 wherein said adaptors on said panel are divided into at least two fields including a first field with fibers angled to a right side of said cabinet and a second field with fibers angled to a left side.

Claim 9

An optical fiber distribution frame comprising: a frame member having walls defining a frame interior, said frame member having a plurality of cabinet attachment locations; a plurality of cabinets sized to be received within said interior; said plurality of cabinets including at least one splice cabinet having means for splicing together optical fibers; and said plurality of cabinets also including at least one storage cabinet having means for temporarily storing excess lengths of optical fibers; said plurality of cabinets including at least one connector cabinet having a panel accessible through both a rear and a forward face of said connector cabinet, a plurality of optical fibers connections including at least a first and second design of connectors of differing known dimensions and selected to couple a pair of optical fibers, said connector cabinet including a plurality of adapters each having attachment means for attachment of said adapters to said panel, said plurality of adapters including at least a first and second design selected to receive and retain said first and second connector design, respectively; said attachment means attaching said adapters to said panel with a first set of fibers connected to first ends of said connectors and extending from a said face and with a second set of fibers connected to second ends of said connectors and extending from said forward face; and attachment means for releasably attaching said plurality of cabinets to said frame member at said attachment locations.

Claim 10

An optical fiber distribution frame comprising: a frame member having walls defining a frame interior, said frame member having a plurality of cabinet attachment locations; a plurality of cabinets sized to be received within said interior; said plurality of cabinets including at least one splice cabinet having means for splicing together optical fibers; and said plurality of cabinets also including at least one storage cabinet having means for temporarily storing excess lengths of optical fibers; said plurality of cabinets including at least one connector cabinet having a panel accessible through both a rear and a forward face of said connector cabinet, a plurality of optical fibers connections including at least a first and second design of connectors of differing known dimensions and selected to couple a pair of optical fibers, said connector cabinet including a plurality of adapters each having attachment means for attachment of said adapters to said panel, said plurality of adapters including at least a first and second design selected to receive and retain said first and second connector design, respectively; said attachment means attaching said adapters to said panel with a first set of fibers connected to first ends of said connectors and extending from a said face and with a second set of fibers connected to second ends of said connectors and extending from said forward face; and attachment means for releasably attaching said plurality of cabinets to said frame member at said attachment locations.

Claim 11

An optical fiber distribution frame according to claim 8 wherein said adapters are provided with means for holding said plurality of connectors at a predetermined angle to said panel with said angle selected to be less than 90°.

Claim 12

An optical fiber distribution frame according to claim 8 wherein said connector cabinet includes openings disposed along forward side edges of said cabinet for fibers to pass through said side edges to said adapters.

Claim 13

An optical fiber distribution frame according to claim 8 wherein said adapters on said panel are divided into at least two fields including a first field holding connectors angled to a right side of said cabinet and a second field holding connectors angled to a left side.
