  2. Electro-optic modulator - Wikipedia

    en.wikipedia.org/wiki/Electro-optic_modulator

    An electro-optic modulator (EOM) is an optical device in which a signal-controlled element exhibiting an electro-optic effect is used to modulate a beam of light. The modulation may be imposed on the phase , frequency , amplitude , or polarization of the beam.

  3. Coherent optical module - Wikipedia

    en.wikipedia.org/wiki/Coherent_optical_module

    Tunable lasers are sometimes used in combination with coherent modulation to allow a module to support various forms of network-based optical switching such as needed in certain cases by an optical mesh networks or a Reconfigurable optical add-drop multiplexer (ROADM). In these, the transmit laser can be tuned to a different optical frequency ...

  4. Optical modulator - Wikipedia

    en.wikipedia.org/wiki/Optical_modulator

    An optical modulator is a device which is used to modulate a beam of light. The beam may be carried over free space, or propagated through an optical waveguide ( optical fibre ). Depending on the parameter of a light beam which is manipulated, modulators may be categorized into amplitude modulators, phase modulators, polarization modulators, etc.

  5. Klystron - Wikipedia

    en.wikipedia.org/wiki/Klystron

    Engineering diagram of a four cavity coaxial gyroklystron at the University of Maryland, IREAP. The gyroklystron has cylindrical or coaxial cavities and operates with transverse electric field modes. Since the interaction depends on the resonance condition, larger cavity dimensions than a conventional klystron can be used.

  6. MIL-STD-1553 - Wikipedia

    Each word is preceded by a 3 μs sync pulse (1.5 μs low plus 1.5 μs high for data words and the opposite for command and status words, which cannot occur in the Manchester code) and followed by an odd parity bit. Practically each word could be considered as a 20-bit word: 3-bit for sync, 16-bit for payload and 1-bit for odd parity control ...

  8. Eye pattern - Wikipedia

    en.wikipedia.org/wiki/Eye_pattern

    In telecommunications, an eye pattern, also known as an eye diagram, is an oscilloscope display in which a digital signal from a receiver is repetitively sampled and applied to the vertical input (y-axis), while the data rate is used to trigger the horizontal sweep (x-axis). It is so called because, for several types of coding, the pattern ...
