1. A fiber optic cassette comprising:
a body defining a front and an opposite rear and an enclosed interior;
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;
an adapter block defining a plurality of fiber optic adapters, the adapter block removably mounted to the cassette body with a first snap-fit interlock structure, each adapter of the adapter 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;
a removable spacer snap-fit to the body defining the enclosed interior, the spacer configured to expand the size of the enclosed interior of the cassette; and
a removable cover configured for enclosing the interior;
wherein optical fibers terminated with fiber optic connectors extend 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 the body comprises a first cassette body and a second cassette body, each defining a separate interior for housing fiber optic equipment and each defining a separate bottom wall for supporting the fiber optic equipment, the first and second cassette bodies separated by the removable spacer snap-fit to both the first and second cassette bodies, wherein the removable cover is snap-fit to the top of the second cassette body, the spacer configured to expand the size of the interior defined by the first cassette body of the cassette; and
wherein the fiber optic cassette further comprises a second snap-fit interlock structure for mounting the cassette to a telecommunications fixture, wherein at least a portion of the second snap-fit interlock structure is defined by the adapter block.
