    POF; Plastic Optical Fiber

    Plastic optical fiber used in data communications or for consumer use.

    OM-x; Multimode Optical Fiber – -generation x

    Multimode optical fibers classified/defined according to their generation. For each generation, a range of performance characteristics is defined. Thus, a third-generation (OM-3) optical fiber will be defined by its core diameter, numerical aperture, linear bandwidth, and attenuation.

    digital aperture; numerical aperture

    Corresponds to the arcsine of the angle formed by the divergence or acceptance cone of an optical fiber.

    FPGA: Field Programmable Gate Array (complex programmable logic component).

    PAM4: Pulse Amplitude Modulation – 4 or 4-state amplitude modulation....
