Structure for optical connections

Claim 2

A structure for optical connections, wherein it comprises substantially parallel elongated supports having two faces each support carrying on one face, on one side, a row of optical connecting boxes extending along the length of the support, each box being provided with a plurality of optical connecting means for connecting optical fibers and located on said one side, and on the other face, level with each box, first means for guiding connecting optical fibers for optically connecting the connecting means to one another and wherein it also comprises second means for guiding these connecting fibers, said second guiding means linking the supports and being placed in the vicinity of the other side thereof facing the boxes of the same level in said supports, the first guiding means associated with each support being adapted for permitting the connecting fibers to travel through said support substantially longitudinally and transversely, from the boxes of said support to boxes of different supports via second guidance means.

Claim 3

A structure according to claim 1, wherein each box serves for the spreading out of optical fibers of an optical cable leading to said box and comprises an orifice for the entry of the cable and at least one drum having a radius permitting the winding on the fibers of the cable.

Claim 4

A structure according to claim 2, wherein each support also comprises on the face carrying the boxes and on the side opposite thereto, a row of reception drums extending parallel to the row of boxes and serving to receive the cables, some of these drums being displaceable parallel to the row of boxes.

Claim 5

A structure according to claim 1, wherein each support also comprises means for returning the connecting fibers from one face to the other of the support, said returning means being located in the vicinity of the optical connecting means and having a curvature compatible with the diameter of the connecting fibers.

Claim 6

A structure according to claim 4, wherein the returning means have grooves for guiding the connecting fibers when they pass from one face to the other of the support.

Claim 7

A structure according to claim 4, wherein said returning means are in the form of a column which is facing the optical connecting means and is fixed to the support and extends along the length thereof.

Claim 8

A structure according to claim 1, wherein it also comprses at least one auxiliary box fixed to a support, on said other face thereof and level with a connecting box, each auxiliary box being intended for the spreading out of optical fibers of another optical cable leading to said auxiliary box and having an orifice for the entry of the other cable, a drum having a radius permitting the winding on of the optical fibers of the other cable and openings for the exit of said fibers respectively in the direction of the connecting box and of the guiding first means corresponding to the other connecting boxes adjacent to said connecting box.

Claim 9

A structure according to claim 7, wherein the support to which the auxiliary box is fixed is provided with an opening in the vicinity of the auxiliary box, said opening permitting the passage of the other optical cable.

Claim 10

A structure according to claim 1, wherein the supports are constituted by elongated plates.

Claim 11

A structure according to claim 1, wherein the first guidance means of each support comprise at the level of each box of said support, a guide means which is fixed to the said other face of said support towards the said one side thereof and another guide means which is fixed to the said other face of said support towards the other side thereof.

Claim 12

A structure according to claim 1, wherein each second guidance means comprise an elongated plate which connects the supports transversely to the length thereof and which is fixed to said supports, and guide means which are fixed to the said elongated plate in correspondence with the respective supports.

Claim 13

A structure for optical connections, wherein it comprises substantially parallel elongated supports having two faces each support carrying on one face, on one side, a row of optical connecting boxes extending along the length of the support, each box being provided with a plurality of optical connecting means for connecting optical fibers and located on said one side, and on the other face, level with each box, first means guiding connecting optical fibers for optically connecting the connecting means to one another and wherein it also comprises second means for guiding these connecting fibers, said second guiding means linking the supports and being placed in the vicinity of the other side thereof facing the boxes of the same level in said supports, the first guiding means associated with each support being adapted for permitting the connecting fibers to travel through said support substantially longitudinally and transversely, from the boxes of said support to boxes of different supports via second guidance means wherein said structure also comprises at least one wavelength multiplexer having an input optically coupled to an optical connecting means of a connecting box and several outputs for optical coupling to optical fibers.

Claim 14

A structure for optical connections, wherein it comprises substantially parallel elongated supports having two faces each support carrying on one face, on one side, a row of optical connecting boxes extending along the length of the support, each box being provided with a plurality of optical connecting means for connecting optical fibers and located on said one side, and on the other face, level with each box, first means guiding connecting optical fibers for optically connecting the connecting means to one another and wherein it also comprises second means for guiding these connecting fibers, said second guiding means linking the supports and being placed in the vicinity of the other side thereof facing the boxes of the same level in said supports, the first guiding means associated with each support being adapted for permitting the connecting fibers to travel through said support substantially longitudinally and transversely, from the boxes of said support to boxes of different supports via second guidance means wherein said structure also comprises at least one wavelength multiplexer having an input optically coupled to an optical connecting means of a connecting box and several outputs for optical coupling to optical fibers.
