A cassette mounting system allows fiber optic cassettes of different sizes to be mounted on the same fiber optic tray or other mounting surface. Cassettes configured for use in the system comprise rails on the left and right sides of the cassette, which are configured to engage with rail guides on the fiber optic tray to facilitate mounting the cassettes on the tray. Adjacent guide rails on the tray define cassette bays within which single-gang cassettes can be installed. Multi-gang cassettes are also configured with clearance areas between the gangs that allow guide rails to reside underneath the cassette when mounted on the tray, allowing both multi-gang cassettes and single-gang cassettes to be installed on the tray. The cassettes include integrated front-facing release mechanisms that can be easily accessed from the front of the tray to facilitate unlocking the cassettes and removing the cassettes from the tray.
