An optical communications repeater is used in a fiber-optic communications system to regenerate an optical signal. Such repeaters are used to extend the reach of optical communications links by overcoming loss due to attenuation of the optical fiber. Some repeaters also correct for distortion of the optical … See more Optical regenerations are classified into 3 categories by the 3 R's scheme. 1. R : reamplification of the data pulse alone is carried out. 2. 2R : in addition to reamplification, pulse reshaping is carried out. E.g.: See more 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, … See more An alternative method of regeneration is through all-optical regenerators without the additional requirement to convert back and forth between optical and electronic signals.
