Disclosed is a dispersion compensating waveguide fiber suitable for use in high data rate, high light power telecommunications systems of intermediate length. The refractive index profile of the compensation fiber is segmented. The core region includes three, four, or five, a central segment (28), a first annular segment (30), a second annular segment (32), a third annular segment (34), and a fourth annular segment (36) having different relative refractive indexes. The segment relative refractive indexes and radii are chosen to provide negative total dispersion and negative total dispersion slope over an extended wavelength range. The index profile design is flexible enough to provide compensated links having total dispersion that is positive, negative, or zero, while maintaining appropriate total dispersion slope compensation. In addition, the waveguide fiber of the invention may be cabled or otherwise buffered prior to its use in a communications system.read more

Optical transmission system
TL;DR: In this paper, an optical transmission system consisting of a light source to output an optical carrier having a predetermined wavelength, a photoelectric converter and an optical modulator disposed on the other end of the optical transmission line to return a portion of the light from the optical transmitter as a reference light to the optical receiver without modulation and to modulate another portion with a transmission signal to return it to the receiver.
