Abstract
An adapter cassette including a housing and an adapter plate that mounts to a front opening of the housing by a snap-fit connection. The adapter cassette also including a cover that mounts to the housing by a snap-fit connection to enclose cable terminations within an interior of the housing. The adapter plate of the adapter cassette can further be mounted directly to a telecommunications panel without the housing for use in applications having non-enclosed cable terminations.
