Abstract

A fiber optic cassette including a body defining a front and an opposite rear and an enclosed interior. A cable entry location is defined in the body for a cable to enter the interior of the cassette. The cable which enters at the cable entry location is attached to the cassette body and the fibers are extended into the cassette body and form terminations at connectors. The connectors are connected to adapters located at the front of the cassette. A front side of the adapters defines termination locations for cables to be connected to the fibers connected at the rear of the adapters. A cable including a jacket, a strength member, and fibers enters the cassette. The strength member is crimped to a crimp tube and is mounted to the cassette body, allowing the fibers to extend past the crimp tube into the interior of the cassette body. A strain relief boot is provided at the cable entry location.

Claims (17)

1. A fiber optic cassette comprising:

a body defining a front and an opposite rear and an enclosed interior;

a cable entry location defined on the body for a cable,

wherein fibers from the cable extend into the cassette body via the cable entry location and form terminations at first connectors that include a ferrule terminating a fiber and a ferrule hub mounted to the ferrule;

wherein the first connectors are connected to a rear side of adapters located at the front of the cassette body, wherein the rear side of each adapter defines a structure for receiving the ferrule and the ferrule hub of one of the first connectors;

wherein a front side of the adapters defines termination locations for fibers to be connected to the fibers connected at the rear side of the adapters, wherein the termination locations are configured to receive second connectors having a different overall configuration than the first connectors connected to the rear side of the adapters, wherein each second connector is one of a traditional SC or a traditional LC connector;

wherein each adapter includes internal structures which allow mating of the first connectors at the rear side with the second connectors at the front side.

2. The cassette of claim 1 , wherein the cable entry location is located at the rear of the cassette body opposite to the front.

3. The cassette of claim 1 , wherein the cassette body defines a top surface and a bottom surface which define major sides of the cassette body and extend between the front and the rear, wherein the adapters along the front are arranged linearly and extend in a longitudinal direction parallel to the major surfaces defined by the top and the bottom of the cassette body.

4. The cassette of claim 3 , wherein the cable at the cable entry location extends parallel to the longitudinal direction.

5. The cassette of claim 1 , further comprising cable radius limiters which provide cable management of the fibers extending to the rear side of the adapters.

6. The cassette of claim 1 , wherein the adapters are in the form of an adapter block that includes a plurality of integrally-molded adapters, each including the front side, the rear side, and internal structures which allow mating of the first connectors at the rear side with the second connectors at the front side.

7. The cassette of claim 6 , wherein the adapter block is removable from a remainder of the cassette body.

8. The cassette of claim 1 , wherein each of the adapters is configured to receive an SC format fiber optic connector at the front side.

9. The cassette of claim 1 , wherein each of the adapters is configured to receive an LC format fiber optic connector at the front side.

10. The cassette of claim 1 , wherein the structure defined at the rear side of each adapter includes a rear clip which retains a split sleeve, and the ferrule hub and the ferrule of a first connector which terminates an interior fiber.

11. The cassette of claim 1 , wherein the cassette can be utilized in a chassis which includes a stationary mount relative to the chassis, or the cassette can be movably mounted, in a variety of sliding movements to allow access to a selected cassette, thereby improving access to a selected second connector attached to the cassette.
