The present invention relates to fiber optic connectors and receptacles, and more particularly, to a cassette capable of holding a plural of fiber optic receptacles for accepting a plural of the same or different fiber optic connectors.
Modern high capacity optical systems often utilize fiber optic ribbons for inter-system connection. As there are multiple connection points in an optical path, there are needs for mating two fiber optic ferrules or a ferrule to another connector. In the mating of two fiber optic ferrules or a ferrule and a connector, the mechanical and optical alignment is paramount. Slight misalignment can result in significant signal loss, especially in the case of ferrules and connectors for multi-fiber optic ribbons and cables. Therefore, there is a need for an adapter that can hold and secure two fiber optic ferrules or a ferrule and a connector in alignment with precision. The adapter design should also allow that installation of the ferrules and connectors that is easy enough for in-field assembly. Further, the adapter should be durable in design and/or material for repeated installations and uninstallations.
According to the present invention, a cassette a first end having a plural of receptacles capable of accepting fiber optic connectors of more than one type, such as CS® push/pull; LC or SC or MPO (multi-push on/off). A second end is configured with a pull-tab handle that accepts a plural of fiber optic strands or cables with optical fibers (e.g. strands) therein, or a plural of corresponding receptacles that are aligned with the first end of the cassette.
A receptacle is configured to accept a fiber optic connector, and secure said connector therein. An auxiliary device such as a hook or latch may be within a receptacle for securing said connector therein. Corresponding structure on a connector may be provided to assist in securing and locking said connector within a receptacle. The cassette may have a top hinged cover with outer latches to be received in a patch panel. A patch panel has a one or more cassettes that accept fiber optic connectors to interconnect opposing groups of fiber optic cabling that may between rooms. A bottom housing accepts a top housing or cover, and the bottom housing may also contain one or more single or duplex fiber optic adapters or receptacles. The other latches may be clips, hooks or a similar fastener to secure the cassette opposite corresponding fiber optic connectors. In another embodiment, a cassette can have one latch with a flange to secure the cassette with a patch panel.
Embodiments of the invention are described in more detail hereinafter with reference to the drawings, in which:
In the following description, apparatuses for mating two multi-fiber optic ferrules and a multi-fiber optic ferrule with a multi-fiber optic connector and the likes are set forth as preferred examples. It will be apparent to those skilled in the art that modifications, including additions and/or substitutions may be made without departing from the scope and spirit of the invention. Specific details may be omitted so as not to obscure the invention; however, the disclosure is written to enable one skilled in the art to practice the teachings herein without undue experimentation.
