Fiber optic cassette, system, and method

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 to enter the interior of the cassette body,

wherein a cable that enters at the cable entry location is attached to the cassette body and fibers from the cable are extended into the cassette body at 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 the adapters are provided in the form of an adapter block that includes a plurality of integrally-molded adapters, each adapter including the front side, the rear side, and internal structures which allow mating with fiber optic connectors at the front side, the adapter block being removable from a remainder of the cassette body.

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 before entry into the cassette body.

5. The cassette of claim 1 , further comprising cable radius limiters which provide cable management of the fibers extending from the cable entry location to the first connectors at the rear side of the adapters.

6. The cassette of claim 1 , wherein each of the plurality of adapters are configured to receive SC format fiber optic connectors at the front end.

7. The cassette of claim 1 , wherein each of the plurality of adapters are configured to receive LC format fiber optic connectors at the front end.

8. 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.

9. 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.
