Abstract

A fiber optic module for installation within patch panel, the fiber optic module comprising a first outer wall with a first rail profile on its outside surface, a second outer wall with a second rail profile on its outside surface, and at least one optical connector. The first outer wall and the second outer wall run parallel to each other. The at least one optical connector is arranged between the first outer wall and the second outer wall. The first rail profile and the second rail profile are complementary to each other such that the fiber optic module may be coupled to an adjacent fiber optic module, wherein the first rail profile of the fiber optic module may be coupled to the second rail profile of the adjacent fiber optic module.

First claim

The invention claimed is:

1. A fiber optic module for installation within a patch panel, the fiber optic module comprising:
a first outer wall having a first rail profile on an outside surface of the first outer wall;
a second outer wall having a second rail profile on an outside surface of the second outer wall; and
an optical connector between the first outer wall and the second outer wall; and wherein
the first outer wall and the second outer wall are oriented parallel to one another; and wherein
the first rail profile and the second rail profile are complementary to each other so that the fiber optic module may be releasably coupled to an adjacent fiber optic module, and wherein the first rail profile of the fiber optic module may be releasably coupled to a second rail profile of the adjacent fiber optic module; and
a snap-in locking device for releasably fixing the fiber optic module to the adjacent fiber optic module when the fiber optic module, and the adjacent fiber optic module, are coupled to each other, the snap-in locking device comprising,
a first spring-loaded locking arm which protrudes from the first outer wall in extension of a longitudinal axis of the first outer wall, and a second spring-loaded locking arm which protrudes from the second outer wall in extension of a longitudinal axis of the second outer wall; and wherein
the fiber optic module is removable from the patch panel by manipulation of the first and second spring-loaded locking arms.

2. The fiber optic module as claimed in claim 1 and wherein the first outer wall is a first side wall; and the second outer wall is a second side wall.

3. The fiber optic module as claimed in claim 1 and further comprising:
plural optical connectors between the first outer wall and the second outer wall.

4. The fiber optic module as claimed in claim 1 and wherein the first rail profile and the second rail profile are aligned along a plug-in direction (x) of the optical connector.

5. The fiber optic module as claimed in claim 1 and wherein a shape of the first rail profile and a shape of the second rail profile are identical, and wherein the second rail profile is rotated by an angle of 180° relative to the first rail profile.

6. The fiber optic module as claimed in claim 1 and wherein each of the first and second rail profiles has one or more identical uniform profile shapes with each identical uniform profile shape having an equal step size which are arranged on top of one another; and wherein
each identical uniform profile shape has a protrusion and a corresponding recession, and the protrusion and the corresponding recession are arranged on top of one another.

7. The fiber optic module as claimed in claim 1 and wherein each first rail profile, and each second rail profile are designed so that the fiber optic module and the adjacent fiber optic module may be coupled in a form-fitting connection in two directions orthogonal to a longitudinal axis of each of the first and second rail profiles.

8. The fiber optic module as claimed in claim 1 and further comprising:
a latching cavity defined in at least one of the first and second rail profiles; and
a latch spring in at least one of the first and second rail profiles.

9. A fiber optic module kit for installation within a patch panel, the fiber optic module kit comprising:
plural fiber optic modules, each of the plural fiber optic modules having,
a first outer wall having a first rail profile on an outside surface of the first outer wall,
a second outer wall having a second rail profile on an outside surface of the second outer wall, and
an optical connector between the first outer wall and the second outer wall, and
the first outer wall and the second outer wall are oriented parallel to one another, and
the first rail profile and the second rail profile are complementary to each other so that the fiber optic module may be releasably coupled to an adjacent fiber optic module, and
the first rail profile of the fiber optic module may be releasably coupled to a second rail profile of the adjacent fiber optic module; and

the plural fiber optic modules are coupled in a row via the first and second rail profiles of adjacent fiber optic modules; and
a snap-in locking device for fixing the fiber optic module to the adjacent fiber optic module when the fiber optic module, and the adjacent fiber optic module, are releasably coupled to each other, the snap-in locking device comprising at least one of,
a first spring-loaded locking arm which protrudes from the first outer wall in extension of a longitudinal axis of the first outer wall, and a second spring-loaded locking arm which protrudes from the second outer wall in extension of a longitudinal axis of the second outer wall, or
a latching cavity defined in at least one of the first rail profile or the second rail profile, and a latch spring in the respective other first or second rail profile.

10. The fiber optic module kit as claimed in claim 9 and wherein at least two of the plural fiber optic modules differ in at least one of size, arrangement of optical connectors, number of optical connectors or type of optical connectors.

11. An optical patch panel for installation in a distribution frame, the optical patch panel comprising:
a fiber optic module kit, the fiber optic module kit having,
plural fiber optic modules, and each of the plural fiber optic modules has,
a first outer all having a first rail profile on an outside surface of the first outer wall,
a second outer wall having a second rail profile on an outside surface of the second outer wall, and
an optical connector between the first outer wall and the second outer wall, and
the first outer wall and the second outer wall are oriented parallel to one another, and
the first rail profile and the second rail profile are complementary to each other so that the fiber optic module may be releasably coupled to an adjacent fiber optic module, and
the first rail profile of the fiber optic module may be coupled to a second rail profile of the adjacent fiber optic module; and
the plural fiber optic modules are coupled in a row via the first and second rail profiles of adjacent fiber optic modules; and

a chassis for receiving the at least one fiber optic module kit and for mounting the patch panel into the distribution frame; and
a snap-in locking device for fixing the fiber optic module to the adjacent fiber optic module when the fiber optic module, and the adjacent fiber optic module, are coupled to each other, the snap-in locking device comprising at least one of,
a first spring-loaded locking arm which protrudes from the first outer wall in extension of a longitudinal axis of the first outer wall, and a second spring-loaded locking arm which protrudes from the second outer wall in extension of a longitudinal axis of the second outer wall, or
a latching cavity defined in at least one of the first rail profile or the second rail profile, and a latch spring in the respective other first rail profile or second rail profile.
