Abstract
With respect to fiber optic structured cabling, dense optical termination and patching platforms, systems, and methods herein involve using an optical-connector adapter cassette that has double rows of adapters on a front portion and at least one goose-neck portion that transitions to a single row of adapters on a rear portion. The double rows of adapters may have virtually no geometry between them. Two cassettes may be cantilevered at the front of a fiber-optic enclosure. The systems includes other aspects.
Claims27
An optical-connector shelf assembly comprising:
- a fiber-optic enclosure having a plurality of enclosure side walls forming an interior portion;
- a plurality of trays at least partially disposed within the interior portion of the fiber-optic enclosure;
- a plurality of optical-connector adapter cassettes including at least a first optical-connector adapter cassette and a second optical-connector adapter cassette supported by the plurality of trays;
- wherein each optical-connector adapter cassette of the plurality of optical-connector adapter cassettes comprises:
- a housing having a front wall, a back wall that is opposite the front wall, a first side wall, a second side wall that is opposite the first side wall, a floor wall, and a cover that together form a cassette interior space,
- wherein the first side wall and second side wall each have a front end and a back end, the front end and the back end being separated by a longitudinal distance D,
- wherein the front end of the first side wall and the front end of the second side wall each have a height H1,
- wherein the back end of the first side wall and the back end of the second side wall each have a height H2, and wherein H1>H2, and a goose-neck section is formed on the first side wall and the second side wall closer to the front portion than the back portion,
- at least one back opening sized and configured to receive a multi-fiber cable adapter on the back wall of the housing, and
- a plurality of front openings on the front wall of the housing sized and configured to receive a plurality of fiber-optic adapters;
- wherein the first optical-connector adapter cassette and the second optical-connector adapter cassette are supported by the plurality of trays with the floor wall of the first optical-connector adapter cassette proximate to the cover of the second optical-connector adapter cassette at a front section proximate the goose-neck section of each and wherein the plurality of trays does not extend between a front section of the first optical-connector adapter cassette and a front section of the second optical-connector adapter cassette;
- wherein for each of the first and second optical-connector adapter cassettes, a slide rail extends laterally on the front section from the first side wall and second side wall, and a lip, which is displaced from the slide rail, also extends laterally at a top portion on each side;
- wherein the plurality of trays comprises a plurality of partitioning walls having a first longitudinal edge and a second longitudinal edge;
- and
- wherein, for the first and second optical-connector adapter cassettes, the lip and the slide rail on each side are sized and configured such that at least one of the plurality of partitioning walls fits and slides between the lip and slide rail.
