摘要： An all optical network for optical signal traffic provides at least a first ring with at least a first clockwise fiber, a second counter-clockwise fiber and a plurality of network nodes. Each node has at least a WDM transponder that with a line-side transmitter and a client-side receiver in a first direction, and a line-side receiver and a client-side transmitter in an opposing second direction. The line-side receiver includes a fixed or a tunable optical wavelength filter. At least a first add and a first drop broadband couplers are positioned on each fiber. Each coupler has first and second ports for through traffic and a third port for adding or dropping local traffic. The first add and first drop broadband couplers are configured to minimize a pass-through loss in each fiber. If there are multiple WDM transponders, their wavelengths are added to the ring either in series or in parallel. All wavelengths dropped from the ring are selected by each individual WDM transponder in a parallel or serial manner.

摘要： An optical signal transmitter is disclosed that transmits an optical signal with corresponding Wavelength Division Multiplexing (WDM) channels and Time Division Multiplexing (TDM) channels. The transmitter is comprised of a laser, a dispersion system, and a modulator. The laser generates and transmits a narrow laser pulse comprised of a plurality of wavelength channels. The dispersion system broadens the narrow laser pulse into a wide laser pulse. The modulator modulates the wide laser pulse based on an electric modulation signal comprised of a plurality of time slot channels wherein the time slot channels in the electric modulation signal correspond to the wavelength channels in the wide laser pulse respectively. The modulator transfers a modulated wide laser pulse. Channels of the modulated wide laser pulse are hybrid wavelength and time slot channels. The transmitter singularly transmits a WDM optical signal comprised of multiple wavelength channels. The transmitter also allows a filter to drop time slot channels from a TDM optical signal instead of an expensive demultiplexer.

摘要： A system for reducing the influence of polarization mode dispersion (PMD) in high speed fiber optical transmission channels. A signal is forward error correction (FEC) encoded according to an FEC code that defines a specified error tolerance per codeword. The invention then effectively randomizes the input polarization of the signal before transmission, in order to reduce the likelihood that PMD will distort one or more codewords beyond the allowed error tolerance. The invention will thereby increase the PMD-limited transmission distance in an optical transmission system.

摘要： A PMD mitigation system is disclosed that is comprised of an interface coupled to a control system. The interface receives an optical signal and transfers the optical signal to the control system. The control system receives the optical signal from the interface, recovers a clock signal from the optical signal, optically reshapes the optical signal using the clock signal to generate a PMD mitigated signal, and transfers the PMD mitigated signal to the interface. The interface transmits the PMD mitigated signal. The PMD mitigation system advantageously mitigates PMD in the optical signal by optically reshaping the optical signal.

摘要： A Metropolitan Area Network (MAN) is disclosed that is comprised of a central node, an optical fiber, a first low insertion loss Optical Add-Drop Multiplexer (O-ADM), a second low insertion loss O-ADM, and a third low insertion loss O-ADM. The first, second, and third O-ADMs are coupled to the optical fiber and configured to drop wavelengths from an optical signal. The first, second, and third O-ADMs each have an insertion loss of less than approximately 1.00 dB. The low insertion loss O-ADMs create an efficient MAN that can grow much larger than current MANs in the absence of optical line amplifiers.
