Abstract

A telecommunications module includes a main housing with an optical component within an interior of the main housing and a fiber optic adapter block coupled to the main housing, the adapter block including a one-piece main body including a top wall and a bottom wall, the adapter block defining a plurality of openings extending from a front end to a rear end of the main body, each opening defining a separate adapter, each opening defining a longitudinal axis, the adapters being configured to receive connectorized cables extending from the optical component within the interior of the main housing, the adapter block including at least one guide rail extending generally between the top wall and the bottom wall of the main body, the guide rail configured for slidably mounting the fiber optic telecommunications module to a telecommunications device once the adapter block has been coupled to the main housing, wherein the main housing includes an integrally formed pivotable latching arm configured to pivot for selectively latching and unlatching the telecommunications module for slidable movement with respect to the telecommunications device.

a top guide located on the top wall of the main body and a bottom guide located on the bottom wall of the main body, the top and bottom guides being parallel to each other and to the longitudinal axes of the openings, the top and bottom guides configured for slidably mounting the fiber optic adapter block to a second telecommunications device.

2. A fiber optic adapter block according to claim 1, wherein the fiber optic adapters are configured for interconnecting SC-type fiber optic connectors.

3. A fiber optic adapter block according to claim 1, wherein the guide rails extend in a non-perpendicular direction with respect to the longitudinal axes of the openings and the top and bottom guides.

4. A fiber optic adapter block according to claim 1, wherein the main body includes eight openings, each defining a separate fiber optic adapter.

5. A fiber optic adapter block according to claim 4, wherein a length of the main body extending from the top wall to the bottom wall is about 3 inches.

6. A fiber optic adapter block according to claim 1, wherein the main body defines a stepped configuration extending from the top wall toward the bottom wall, wherein each of the fiber optic adapters are offset to one another in a direction along the longitudinal axes.

7. A fiber optic adapter block according to claim 6, wherein the guide rails define a first slope extending between the top wall and the bottom wall, the first slope being generally equal to a second slope defined by the stepped configuration of the main body.

8. A fiber optic telecommunications module comprising:

a main housing portion including a top wall, a bottom wall, a first transverse sidewall, a rear wall, an open front end, and an open second side, the main housing portion including an optical component therewithin;

a cover portion coupled to the main housing portion to close up the open second side of the main housing portion and keep the optical component within the main housing portion;

a fiber optic adapter block coupled to the main housing portion to close the open front end of the main housing portion, the fiber optic adapter block including a one-piece main body, the main body including a top wall and a bottom wall, the fiber optic adapter block defining a plurality of openings extending from a front end to a rear end of the main body, each opening defining a separate fiber optic adapter, each opening defining a longitudinal axis, the fiber optic adapters being configured to receive connectorized cables extending from the optical component within the main housing portion, the fiber optic adapter block including at least one guide rail extending generally between the top wall and the bottom wall of the main body, the guide rail configured for slidably mounting the fiber optic telecommunications module to a first telecommunications device once the fiber optic adapter block has been coupled to the main housing portion;

wherein the fiber optic adapter block and the main housing portion include intermating keys for slidably coupling the fiber optic adapter block to the main housing portion in a direction extending along the longitudinal axes of the openings defining the adapters; and

wherein the main housing portion includes an integrally formed pivotable latching arm, the latching arm configured to pivot for selectively latching and unlatching the telecommunications module for slidable movement with respect to the first telecommunications device.

9. A fiber optic telecommunications module according to claim 8, wherein the main body includes a closed first side and an open second side, wherein a fiber optic connector ferrule alignment structure is mounted within each of the openings of the main body, the fiber optic connector ferrule alignment structure including a sleeve for aligning ferrules and a sleeve mount for receiving the sleeve, the fiber optic connector ferrule alignment structure mounted within the opening in a direction extending from the open second side toward the closed first side of the main body and a cover panel is coupled to the main body to close the open second side of the main body to capture the fiber optic connector ferrule alignment structures within the main body.

10. A fiber optic telecommunications module according to claim 9, wherein the at least one guide rail of the fiber optic adapter block includes a pair of parallel guide rails, one of the guide rails located on the main body, the other of the guide rails located on the cover panel.
