Patent Number Title Of Patent Date Issued
6141090 Fiber optic cable having a specified path average dispersion October 31, 2000
Fiber optic cable waste is avoided by measuring amplitude oscillations of four-wave mixing products in positive-dispersion and negative-dispersion fiber optic cable to determine the lengths of a first, positive-dispersion cable segment and a second, negative-dispersion cable segment that
6072615 Phase modulator-based generation of high-quality high bit rate return-to-zero optical data strea June 6, 2000
Apparatus and method for generating a return-to-zero (RZ) optical data stream. A laser or other continuous wave (CW) optical source generates an optical carrier signal which is applied to a phase modulator. A return-to-zero data generator multiplies a non-return-to-zero (NRZ) electri
6011615 Fiber optic cable having a specified path average dispersion January 4, 2000
Fiber optic cable waste is avoided by measuring amplitude oscillations of four-wave mixing products in positive-dispersion and negative-dispersion fiber optic cable to determine the lengths of a first, positive-dispersion cable segment and a second, negative-dispersion cable segment that
5956131 System and method for mapping chromatic dispersion in optical fibers September 21, 1999
A system and method in which the chromatic dispersion characteristic, as a function of distance along a section of transmissive fiber, is measured. First and second optical signals are launched into a fiber under test to thereby generate, by a four-wave mixing process in the fiber, a pro
5473458 Soliton data transmission using non-soliton transmitter December 5, 1995
Method and apparatus of soliton transmission using a non-soliton source are described. The soliton transmission is generally in the form of an optical pulse sequence, Intensity and phase modulation of a continuous wave optical signal generates a pair of optical pulse sequences related to
5463489 Soliton transmission system having sliding-frequency guiding filters with particular filter stre October 31, 1995
A soliton transmission system comprising optical filters whose center frequency intentionally differs from the center frequency of adjacent optical filters is disclosed, wherein the filter strength .eta. of the filters is between about 0.3-0.5, and preferably is 0.4. The center frequ
5432631 Dual-wavelength source of high-repetition rate, transform-limited optical pulses July 11, 1995
A method and apparatus for producing high quality optical pulse trains at a high repetition rate first phase modulates a cw optical signal with an external phase modulator. The central optical frequencies (i.e., the carrier frequency and at least one pair of sidebands) of the phase m
