ABSTRACT:
The present invention provides modular optical amplifier constituents suitable for constructing optical amplifiers of various designs and modular fiber optic cassettes. Each stage of a multiple stage optical amplifier is housed in a separate optical cassette. Optical pump(s) are separately packaged in pump modules to further simplify amplifier design and enhance amplifier manufacturability. In an exemplary embodiment, a modular optical amplifier is constructed comprising a first amplifier housing including a first optical cassette for holding a first amplifier stage. Cassette regions are provided for receiving one or more passive optical components used with the first stage of the optical amplifier. A first length of rare-earth doped optical fiber is retained by cassette retaining projections and optically communicates with a pump interconnection element. A second amplifier housing is provided comprising a second optical cassette for holding a second amplifier stage in a substantially similar manner as the first optical cassette. At least one optical pump is retained in an optical pump housing separate from the first and second optical cassettes for supplying pump energy to the optical amplifier. The cassettes are optionally mounted vertically or adjacent one another on a circuit board. The circuit board may include electrical circuits for monitoring amplifier performance and for passing the monitoring information to a network management system.
