Claim:
1. An optical fiber cassette adapted for use as an interface between a multi-fiber network cable and a plurality of patch fibers that terminate in respective optical fiber plug connectors, the cassette comprising: a base having a flat panel that defines a splice tray, the splice tray including an outer radius limiter on which slack fan-out fibers of a connector pigtail assembly are coiled; an adapter plate at a proximal end of said base on which are arranged an array of connectors to which respective ones of said fan-out fibers are terminated, said connectors each being configured to receive a jumper plug connector having an associated jumper fiber; and at least one slide member arranged on a side wall of said base to permit the cassette to be mounted in a frame and to be pulled out proximately for access to said connectors and said splice tray, and to be pushed in distally for normal operations; a cover plate held on said base above said splice tray, and including at least an inner radius limiter on which a plurality of slack coils of a multi-fiber network cable are disposed, such that the slack coils of said network cable are situated in a generally annular space defined between said outer and said inner radius limiters; and a slide-on/off or snap-on/off U-guard connector cover removably attached onto said base at the proximal end thereof over said adapter plate, the U-guard connector cover being adapted to be pulled off proximally and detached from the base and reattached by pushing it distally into place on said adapter plate, and being formed of a top wall and a bottom wall extending proximally to a front wall connecting the top and bottom walls, and having open sides to permit the jumper fibers to exit.
