Abstract: An optical transmission system having optical transmit and receive filters having passbands adjusted or selected for opposite and equal wavelength offsets from the optical wavelength of a carrier or the channel center wavelength.

Abstract: A method of increasing capacity on a long-haul undersea cable system having at least one optical fiber, said method comprising interleaving counter-propagating forward-propagating and backward-propagating signals in forward and backward channels on a common optical fiber, wherein the wavelength offset between said forward and backward channels is typically half of the channel spacing of co-propagating signals.

Abstract: There is enclosed a new optical signal detection scheme by means of converting transmitted optical RZ pulses to NRZ pulses. An optical fiber transmission system which uses the RZ format as the transmission format, and uses an optical pulse transformer to transform the optical RZ format to NRZ format in front of the receiver, then uses the NRZ format as the detection format at the receiver. One optical pulse transformer, which comprises an optical pre-amplifier, an optional optical filter and a span of normal dispersion fiber to transform high power optical RZ pulses to optical NRZ pulses by the combination effects of self-phase modulation and normal dispersion, is proposed and demonstrated. The tolerances for both the generalized timing jitter and amplitude jitter are increased significantly by using this invention. The Q factor is also increased by as much as 5.4 dB, which is a significant improvement on system performance.

Abstract: A method of increasing usable bandwidth on a long-haul cable system having at least one optical fiber, the method comprising the steps of: (a) effecting counter-propagating first and second signals of different bands on a common long-haul optical fiber having cascaded optical amplifiers; and (b) band amplifying the first and second signals while reducing BRS in the bands.

Abstract: A gain-clamped, optical amplifier includes a rare-earth doped fiber and a source of pump energy coupled to the rare-earth doped fiber. The doped fiber serves as a gain medium that is optically pumped by the pump source. A wavelength-selective optical feedback loop is coupled between input and output ports of the rare-earth doped fiber. The feedback loop supports a compensating lasing signal, which is a pulsed signal located at a wavelength different from a signal wavelength.
