摘要： A bit synchronization circuit composed of a multiphase data sampling unit for converting each received burst data sets to multiphase data trains, a phase determination unit for generating a control signal indicating an optimum phase data train, an output data selector for selectively passing optimum phase data train indicated by the control signal, and a data synchronization unit for converting the optimum phase data train to a data train in synchronization with a reference clock. The phase determination unit repeatedly detecting the optimum phase data train during the same burst data set is received. When optimum phase varies, the output data selector dynamically switches the optimum phase data train to be supplied to the data synchronization unit.

摘要： An optical path cross-connect device includes a wavelength branching unit, an intra office signal input unit, nullmnull pieces of routing units, a wavelength combining unit and an intra-office signal output unit. The routing units input thereinto an optical signal outputted from either of the wavelength branching unit and the intra-office signal input unit via a first optical path group, and convert an input optical signal into a predetermined wavelength to thereby output a wavelength-converted optical signal to a second optical path group. The nullmnull (symbol being an integer and also being larger than 1)null pieces of routing units are subdivided into units of at least nulln (symbol nullnnull being an integer and also being larger than 1)null wavelengths, as wavelength ranges to be processed by the respective routing unit are different from each other.

摘要： A method of deflection routing a packet in an all-optical communication network is described. Routing and destination information is contained in the address header of the packet and is generated by the originating node while still in the electrical domain before conversion to the optical domain. Receiving nodes process the address header in the optical domain using the information for their node from the address header. The address header is comprised of N node fields where N is the number of nodes on the optical network. Each node field contains routing information for a node on the optical network. Each node field contains at least one port field containing routing and address information associated with a port in the node.

摘要： In a method of analyzing an optical communications signal, a threshold is established under control of a processor, and a decision circuit compares the amplitude of the signal to the threshold. A counter samples the output of the decision circuit and counts, over many periods of the signal, those samples indicating that the amplitude of the signal is above the threshold. The threshold generating, comparing, and counting are repeated for several thresholds within a range corresponding to an expected amplitude range of the signal. The stored counts and thresholds represent an amplitude histogram N(VT) for the signal. The derivative dN/dVT of the function N(VT) represents the probability density function (PDF) for the signal amplitude and can be used to derive performance information such as bit error rate and optical signal-to-noise ratio (OSNR).

摘要： The multi-channel optical transmitter is composed of a tunable optical signal source, an optical multiplexer and an intensity reducer. The tunable optical signal source includes a tunable laser, and additionally includes an optical signal output through which it outputs an optical signal to one of the inputs of the optical multiplexer. The intensity reducer is for reducing the intensity of the optical signal output by the optical signal source during tuning of the tunable laser. The intensity reducer prevents the tunable optical signal source from injecting high levels of noise into the channels during tuning of the tunable optical signal source.

摘要： In a ring network comprising a plurality of nodes and a 16 channel coarse wavelength-division multiplexing (CWDM) plan, a technique is disclosed for adding and dropping channels that reduces the maximum attenuation loss that any channel encountersnullthereby enabling longer rings to be constructed without using optical amplifiers in the ring. The 16 channels are typically distributed between the wavelengths 1310-1610 nm with 20 nm separation between channels. It is obscured that glass fibers have gradually decreasing loss at longer wavelengths in this band. The network includes a hub and several nodes that are interconnected by optical fibers in a ring configuration, where distance from the hub is the minimum value measure in either the clockwise or counterclockwise direction. Channels are assigned to the various nodes based on their wavelength. The channels whose wavelengths are near 1310 nm are assigned to nodes that are progressively closer to the hub.

摘要： The is directed to extending wavelength routing on a metro network subtended off an optical agile network. Flexibility on the subtended metro network is obtained by either tuning the head-end transmitter on a metro wavelength that is the operating wavelength of the route to a specified tail-end node (tunable source, fixed wavelength-route dependency) or/and tuning a specified route to the metro wavelength (fixed source, tunable wavelength-route dependency). The routes may be tuned at one or both ends.

摘要： Disclosed is a novel method of allocating resources within an optical network in order to establish an optical path between a first node and a second node. A query signal, proposing a wavelength and timeslot pairing is sent to switching elements along a proposed optical path from the first node to the second node. The query signal is provided along with data indicating the availability of the switching elements along the proposed path. The query signal and data are used to determine an appropriate wavelength and timeslot pairing. When a wavelength and timeslot pairing has been chosen the appropriate switching elements are instructed to support the wavelength timeslot pairing along the optical path.

摘要： In a WDM optical transport network, numerous optical data signals are multiplexed together to form a single optical system signal. The optical system signal may be constituted in an optical line hierarchy that defines a plurality of optical layers within the optical transport space. In accordance with the present invention, an architectural arrangement is provided for a network switching node within a WDM optical transport network. The architectural arrangement for the network switching node employs at least one switching device at each optical layer. The improved inter-workings amongst the optical layers of the network switching node leads to improved scalability, manageability, operational simplicity and affordability of optical transport networks.
