摘要： An all-optical modulation format converter for converting optical data signals modulated in an on-off-keying (OOK) format to a phase-shift-keying (PSK) format. The OOK-to-PSK converter can be coupled to a delay-line interferometer to provide an all-optical wavelength converter for differential PSK (DPSK). The OOK-to-PSK converter can also be used in all-optical implementations of various functions, including, for example, exclusive-OR (XOR) logic, shift registers, and pseudo-random binary sequence (PRBS) generators.

摘要： A telecommunications system and constituent integrated circuit that includes a post-amplifier assembly configured for communication with an optical receiver, a laser driver assembly configured for communication with the optical transmitter, and a controller assembly configured to control the post-amplifier and laser driver. The post-amplifier, the laser driver, and the controller assemblies are embodied on a single integrated circuit, thereby reducing manufacturing costs. Noise due to clock generation may be reduced by having the clock act on a transient basis, turning on when needed during the boot process, and turning off when not needed during normal operation.

摘要： A communication network system has a plurality of communication terminals, each having a first transmitting unit and a first receiving unit. Information is transmitted and received among the communication terminals through the first transmitting unit and the first receiving unit. At least two of the communication terminals are used as relay terminals. Each of the relay terminal has a second transmitting unit and a second receiving unit for performing only one-to-one-type communication. A received-information relay unit transmits information received from the first receiving unit to the second transmitting unit and transmits information received from the second receiving unit to the first transmitting unit. A relay-terminal-information transmitting unit transmits to the first transmitting unit ID information of the relay terminal and ID information of a terminal to which the relay terminal is providing relay services. A storage unit stores the information of the relay terminals and relay situations thereof from relay terminal information received from the first receiving unit. When the relay terminal discontinues the relay services, the presence or the absence of an available relay terminal is determined by referring to the storage unit. If there is an available relay terminal, an instruction is provided to the terminal which is receiving the relay services to change the relay terminal.

摘要： A wavelength converter and a wavelength division-multiplexing optical communication apparatus automatically generate clock signals of a specified frequency that match send/receive digital signals and regenerates timing for the send/receive digital signals. The wavelength converter includes: optical/electrical signal converters (2A, 2B) that convert input optical signals into electric digital signals; clock generator circuits (4A, 4B) that automatically identify the transmission mode for digital signals and generate phase-synchronized clocks of a specified frequency that match the signal transmission mode; timing regeneration circuits (6A, 6B) that regenerate clock timing for the digital signals based upon the phase-synchronized clocks from the clock generator circuits; and electric/optical converters (3A, 3B) that convert the digital signals from the timing regeneration circuits into optical signals of a specified wavelength.

摘要： The present invention relates to a technique suitable for the enhancement of efficiency of wavelength allocation in an optical network. A transmission capability for each of a plurality of wavelengths available in the optical network is calculated to allocate, to a recommendation optical transmission path in the optical network for a traffic demand from the external, a wavelength having a transmission capability corresponding to a total optics transmission distance of the recommendation optical transmission path on the basis of a result of the calculation. This enables considerably reducing the number of optical repeaters to be disposed, each of which has an electrical signal regeneration function in the optical network, thereby reducing the number of devices, dissipation power, installation area and others in the optical network.

摘要： An optical transmission device has an optical amplifier, first and second control signal reception units and a transmission unit. The first control signal reception unit receives control signals from a receiving end optical service channel. The second control signal reception unit receives control signals from an operator. The transmission unit transmits to the optical amplifier, either the control signals from the receiving end optical service channel or the control signals from the operator so that the optical amplifier operates in either an automatic level control mode or an automatic gain control mode.

摘要： The present invention is directed toward a distributed intelligence fiber-optic communication network in which node control processors (NCPs) associated with each network element periodically transmit identification and status information to the other NCPs in the network. Various faults in the network can thus be readily identified, and appropriate tasks for modifying the network in response to the fault (such as rerouting around a defective network element) can be carried out. Further, information continues to be distributed among the NCPs even if a break occurs in a segment of fiber in the network.
