摘要： An optical communication system having an optical transmitter and an optical receiver optically coupled via a multi-path fiber. The optical transmitter launches, into the multi-path fiber, an optical transverse-mode-multiplexed (TMM) signal having a plurality of independently modulated components by coupling each independently modulated component into a respective transverse mode of the multi-path fiber. The TMM signal undergoes inter-mode mixing in the multi-path fiber before being received by the optical receiver. The optical receiver processes the received TMM signal to reverse the effects of inter-mode mixing and recover the data carried by each of the independently modulated components.

摘要： A representative optical receiver of the invention receives an optical transverse-mode-multiplexed (TMM) signal through a multimode fiber that supports a plurality of transverse modes. The optical receiver has a plurality of optical detectors operatively coupled to a digital signal processor configured to process the TMM signal to determine its modal composition. Based on the determined modal composition, the optical receiver demodulates each of the independently modulated components of the TMM signal to recover the data encoded onto the TMM signal at the remote transmitter.

摘要： An apparatus includes an all-optical transmission line having, at one wavelength, a pair of relatively orthogonal optical propagating modes whose local group velocities differ along a part of the all-optical transmission line. The all-optical transmission line is formed by a sequence of optically end-connected multi-mode fiber segments. The segments include, at least, 80% of the optical path length of the all-optical transmission line. Each segment is configured such that a differential group delay between the pair varies monotonically there along and changes by, at least, 200 pico-seconds thereon.

摘要： A process optically transports digital data over an all-optical long-haul communication path. The process includes transporting digital optical data signals at a selected bit rate and a selected wavelength over a sequence of transmission spans. The sequence includes 70 percent or more of the spans of the long-haul all-optical communication path. Each span of the sequence has a primary local maximum optical power point for the wavelength on a transmission fiber and nearest to an input of the span. The transporting causes a cumulative dispersion of each signal to evolve such that residual dispersions per span are positive over some of the spans and are negative over other of the spans. At the primary local maximum power points, magnitudes of cumulative dispersions of the signals in pico seconds per nanometer remain at less than 32,000 times the inverse of the bit rate in giga bits per second.

摘要： An improved single-channel (SC) or Wavelength-Division Multiplexed (WDM) fiber optic system has post-transmission dispersion compensation using positive and negative compensation selected according to the residual dispersion slope of the fiber link on a per channel basis. A transmitter (TX) is coupled to a receiver (RX) through transmission fibers including standard unshifted fibers (STD) or any other transmission fiber types, compensated by a dispersion-compensating fibers (DCFs). Amplifier units are installed at defined intervals referred to as amplifier spacing. Dispersion-compensating fibers (DCFs) are typically installed between the first and second stage amplifiers. By using dispersion compensation at the end of the line, system performance improves significantly without changing the length of DCF in all amplifiers. Adjusting the dispersion at the end of the line is achieved by increasing or reducing the length of DCF in the last amplifier or by using any other dispersion compensating devices such as fiber Bragg gratings, etc.
