Abstract
The cassette is mounted horizontally or vertically on a support rail and defines a front action face. One of its compartments is used for storing an excess length of optical cable while its other compartment is used for storing an excess length of optical jumper. The cassette includes a fixed first connection for the cable conductor and a removable cross-connection second connection for the jumper, said connections being mounted separately, substantially on the front action face, and being interconnected by an optical lead which is wound down together with the cable conductor and in the same compartment. The cassette is applicable to a distribution frame for telephones or computers.
Claims17
An optical connection cassette which is generally rectangular and flat in overall shape having two large faces and four small faces in two opposite pairs, and having two compartments on opposite sides of an internal separation web extending parallel to said large faces, wherein the cassette has two of said opposite small faces along two edges of said web respectively defining a "front" action face and a "rear" fixing face which is fitted with cassette mounting and fixing means for mounting and fixing the cassette on a support under operating conditions, each of the two compartments being accessible through at least one of said front action face and said rear fixing face, wherein a "first" one of the compartments is used for storing an excess length of at least one conductor of an optical cable, and a "second" one of said compartments is used for independently storing an excess length of an optical jumper for each of the corresponding cable conductors coiled down in the first compartment, and for connection thereto, and wherein the cassette further includes individual optical connection means for connecting each jumper to each corresponding cable conductor, said individual optical connection means being mounted substantially on said front action face.
An optical connection cassette which is generally rectangular and flat in overall shape having two large faces and four small faces in two opposite pairs, and having two compartments on opposite sides of an internal separation web extending parallel to said large faces, wherein the cassette has two of said opposite small faces along two edges of said web respectively defining a "front" action face and a "rear" fixing face which is fitted with cassette mounting and fixing means for mounting and fixing the cassette on a support under operating conditions, each of the two compartments being accessible through at least one of said front action face and said rear fixing face, wherein a "first" one of the compartments is used for storing an excess length of at least one conductor of an optical cable, and a "second" one of said compartments is used for independently storing an excess length of an optical jumper for each of the corresponding cable conductors coiled down in the first compartment, and for connection thereto, and wherein the cassette further includes individual optical connection means for connecting each jumper to each corresponding cable conductor, said individual optical connection means being mounted substantially on said front action face, wherein said first and second compartments are delimited by a peripheral rim projecting in both directions from the web around at least three of the sides of the second compartment, thereby defining two side walls and the rear wall therefore, and discontinuously around four of the sides of the first compartment, thereby defining a nearly closed front face therefore belonging to the action front face of the cassette, two side walls, and a rear face having rear accesses through which each of the cable conductors wound down in said first compartment reaches said first compartment, and wherein it includes the cassette mounting and fixing means constituted by two sets of individual snap-fastening resilient tabs projecting over substantially the entire height of the rear walls of the two compartments.
An optical connection cassette which is generally rectangular and flat in overall shape having two large faces and four small faces in two opposite pairs, and having two compartments on opposite sides of an internal separation web extending parallel to said large faces, wherein the cassette has two of said opposite small faces along two edges of said web respectively defining a "front" action face and a "rear" fixing face which is fitted with cassette mounting and fixing means for mounting and fixing the cassette on a support under operating conditions, each of the two compartments being accessible through at least one of said front action face and said rear fixing face, wherein a "first" one of the compartments is used for storing an excess length of at least one conductor of an optical cable, and a "second" one of said compartments is used for independently storing an excess length of an optical jumper for each of the corresponding cable conductors coiled down in the first compartment, and for connection thereto, and wherein the cassette includes individual optical connection means for connecting each jumper to each corresponding cable conductor, said individual optical connection means being mounted substantially on said front action face and wherein said cassette further includes retention means for supporting said optical connection means parallel to said front action face.
