A fiber optic telecommunications device includes a frame and a fiber optic module including a rack mount portion, a center portion, and a main housing portion. The rack mount portion is stationarily coupled to the frame, the center portion is slidably coupled to the rack mount portion along a sliding direction, and the main housing portion is slidably coupled to the center portion along the sliding direction. The main housing portion of the fiber optic module includes fiber optic connection locations for connecting cables to be routed through the frame. The center portion of the fiber optic module includes a radius limiter for guiding cables between the main housing portion and the frame, the center portion also including a latch for unlatching the center portion for slidable movement. Slidable movement of the center portion with respect to the rack mount portion moves the main housing portion with respect to the frame along the sliding direction.

1. A telecommunications module comprising: a fixture;a fiber optic cassette mounted to the fixture via a first snap-fit interlock structure, the fiber optic cassette including: a body defining an open front and an opposite rear wall and an enclosed interior, the body further defining a horizontal rear extension that is located outside of the enclosed interior that projects rearward from the rear wall, the horizontal rear extension defining at least one vertical wall;a fiber optic signal entry location defined on the body for a fiber optic signal to enter the interior of the cassette via a fiber optic cable, the fiber optic signal entry location defined by at least one LC format fiber optic adapter that is mounted to the at least one vertical wall of the horizontal rear extension with a snap-fit interlock;an adapter block defining a plurality of fiber optic adapters, the adapter block removably mounted to the cassette body via a second snap-fit interlock structure to close the open front of the body, each adapter of the block including a front outer end, a rear inner end, and internal structures which allow mating of fiber optic connectors that are mounted to the front and rear ends, respectively;optical fibers terminated with fiber optic connectors extending from the fiber optic signal entry location to the rear inner ends of at least some of the fiber optic adapters of the snap-fit adapter block for relaying the fiber optic signal to fiber optic connectors to be coupled to the front outer ends of the adapters;wherein at least a portion of the first snap-fit interlock structure is defined by the adapter block. 2. A telecommunications module according to claim 1, wherein the first snap-fit interlock structure is configured to allow the adapter block to be mounted to the fixture without the remainder of the fiber optic cassette. 3. A telecommunications module according to claim 1, wherein the at least one LC format adapter is a duplex LC adapter. 4. A telecommunications module according to claim 3, wherein the at least one LC format adapter is a pair of duplex LC adapters. 5. A telecommunications module according to claim 1, wherein the at least one LC format adapter includes at least one flange that is slidably inserted into a notch defined by the at least one vertical wall of the horizontal rear extension. 6. A telecommunications module according to claim 1, wherein the at least one vertical wall defined by the horizontal rear extension includes an exterior vertical wall and a divider structure that is positioned between the rear wall of the body and the exterior vertical wall of the horizontal rear extension. 7. A telecommunications module according to claim 6, wherein the at least one LC format adapter is a pair of duplex LC adapters and the pair of duplex LC adapters include flanges that are slidably inserted into notches defined by each of the rear wall of the body, the divider structure, and the exterior vertical wall. 8. A telecommunications module according to claim 7, wherein each of the rear wall of the body, the divider structure, and the exterior vertical wall includes horizontal tabs that are configured to snap over bodies of the duplex LC adapters to retain the adapters. 9. A telecommunications module according to claim 1, wherein the horizontal rear extension defines an opening for accessing the at least one LC format fiber optic adapter to push the LC format fiber optic adapter from the bottom for removal thereof. 10. A telecommunications module according to claim 1, wherein the at least one LC format adapter is configured to receive and mate an exterior connectorized fiber optic cable to a connectorized fiber optic pigtail, wherein the pigtail is crimped to the cassette body before relaying the optical fibers of the pigtail to the rear inner ends of at least some of the fiber optic adapters of the adapter block at the front of the cassette. 11. A telecommunications module according to claim 10, wherein the fiber optic pigtail includes a jacket, a strength member, and the fibers, wherein 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. 12. A telecommunications module according to claim 11, wherein the cassette body defines curved portions adjacent the crimp tube for providing bend radius protection to the fiber optic pigtail without the use of a strain relief boot. 13. A telecommunications module according to claim 10, wherein the cassette body defines crimp locations at both a right side and a left side of the body such that the at least one LC format adapter can receive the exterior connectorized fiber optic cable from either of the right side or the left side of the body. 14. A telecommunications module according to claim 1, wherein the adapters of the adapter block are integrally formed with the block as a unitary piece. 15. A telecommunications module according to claim 1, further comprising an optical device within the interior of the cassette configured to process the fiber optic signal entering the cassette at the fiber optic signal entry location. 16. A telecommunications module according to claim 15, wherein the optical device includes a thin film filter. 17. A telecommunications module according to claim 1, further including radius limiters for guiding the optical fibers from the signal entry location to the rear inner ends of the fiber optic adapters of the adapter block. 18. A telecommunications module according to claim 17, wherein the radius limiters include removable cable retention fingers. 19. A telecommunications module according to claim 1, wherein the fiber optic adapters of the adapter block are also of LC format. 20. A telecommunications module according to claim 1, wherein the fixture defines a rack mount portion, a center portion, and a main housing portion, wherein the rack mount portion is configured to be stationarily coupled to a telecommunications frame, the center portion is slidably coupled to the rack mount portion along a sliding direction, and the main housing portion is slidably coupled to the center portion along the sliding direction, the fiber optic cassette mounted to the main housing portion of the fixture, the center portion including a radius limiter for guiding cables between the fiber optic cassette and the telecommunications frame, the center portion also including a latch for unlatching the center portion for slidable movement, wherein slidable movement of the center portion with respect to the rack mount portion moves the main housing portion with respect to the telecommunications frame along the sliding direction. 21. A telecommunications module according to claim 20, wherein when the center portion is moved with respect to the rack mount portion, the center portion is configured to move at half the linear speed of the main housing portion with respect to the rack mount portion.
