Abstract: An optoelectronic module includes a housing and a printed circuit board (“PCB”) positioned within the housing. A positioning member is coupled to the PCB and includes one or more receptacles each configured to receive and secure positioning of an optical component relative to the PCB. The positioning member may include a plurality of receptacles positioned relative to one another in an arrangement defining a vertical array of receptacles, a lateral array of receptacles, or both. In one form, an optical component, when positioned in a receptacle of the positioning member, is spaced from the PCB. The positioning member may be formed of a thermally insulative or thermally conductive material, and a number of optical fibers may be routed between the positioning member and the housing.

Abstract: Systems and methods are provided for short fiber length multi-core fiber (MCF) Erbium-doped fiber amplifiers (EDFAs). An enhanced Erbium-doped fiber amplifier (EDFA) includes one or more pumps configured to pump light during the amplifying, and a multiple-core fiber (MCF) doped with an active dopant for communicating the signal light within the EDFA during the amplifying. The multiple-core fiber (MCF) is in optical communication with the signal light and is in optical communication with the one or more pumps, where the amplifying included applying a plurality of gain sections, with each gain section associated with a corresponding fiber length, and where applying one or more of the plurality of gain sections including use of one or more loops via one or more corresponding cores in the multiple-core fiber (MCF). The multiple-core fiber (MCF) is an Erbium-doped fiber (EDF).
