Optical Communications Repeater - Electronic Vs Optical Regeneration

Electronic Vs Optical Regeneration

Due to the high data rates that can be achieved with optical systems, OEO repeaters are expensive to implement as electronics to handle those high data rates are expensive and difficult to construct. Also, since one repeater is required for each wavelength, and many tens of wavelengths may be transmitted down a single fibre, a lot of equipment is required for each fibre. In contrast, an optical amplifier can amplify all of the wavelengths in a single device. An amplifier does not provide the regeneration ability of a repeater, but loss, rather than distortion is generally the limiting factor in the design of communications system.

Famous quotes containing the words electronic, optical and/or regeneration:

    The new electronic interdependence recreates the world in the image of a global village.
    Marshall McLuhan (1911–1980)

    It is said that a carpenter building a summer hotel here ... declared that one very clear day he picked out a ship coming into Portland Harbor and could distinctly see that its cargo was West Indian rum. A county historian avers that it was probably an optical delusion, the result of looking so often through a glass in common use in those days.
    —For the State of New Hampshire, U.S. public relief program (1935-1943)

    Typically, the hero of the fairy tale achieves a domestic, microcosmic triumph, and the hero of myth a world-historical, macrocosmic triumph. Whereas the former—the youngest or despised child who becomes the master of extraordinary powers—prevails over his personal oppressors, the latter brings back from his adventure the means for the regeneration of his society as a whole.
    Joseph Campbell (1904–1987)
