摘要： A wavelength division multiplexer (WDM) unit (12) includes a plurality of Input/Output cards (IOCs 14). Each IOC is bidirectionally coupled to I/O specific media (fiber or copper) and to two coaxial cables. Also bidirectionally coupled to the coaxial cables are a plurality of Laser/Receiver Cards (LRC 20). The interface between the IOCs and the LRCs is an Emitter Coupled Logic (ECL) electrical interface that is conveyed over the coaxial cables. Each LRC is bidirectionally coupled by two single mode fibers to an optical multiplexer and demultiplexer, embodied within a grating (24). An input/output port of the grating is coupled to a fiber link (28) that enables bidirectional, full duplex data communications with a second WDM. Each WDM also includes a Diagnostic Processor Card (DPC 28) that receives status signals from the IOCs and LRCs, that forwards the status signals on to an external processor, and which generates control information for the IOCs and LRCs.

Each IOC is associated with one of a plurality of communications channels and includes an I/O specific media connector (30) that is coupled to an appropriate transmitter (Tx) and receiver (Rx). The I/O specific media connector, Tx and Rx are constructed and operated in accordance with the specific data stream type that is input to and output from the associated channel of the WDM. By example, a first data stream may be conveyed through an optical (fiber) conductor in accordance with an ESCON protocol at 200 Mb/s, and a second data stream may be conveyed through an electrical (copper) conductor in accordance with an ECL non-specific protocol at up to 622 MB/s.

摘要： The invention is a system and method for improving the signal-to-noise ratio of an electrical data signal transmitted between two electronic modules. An electrical data signal from a first module is amplified by an electrical amplifier to produce an amplified electrical data signal. The electrical amplifier is supplied by a power distribution network. The amplified electrical data signal has a power level sufficiently low such that the electrical amplifier does not cause significant disturbances in the power distribution network so that a plurality of the electrical amplifiers can be proximately located and operated concurrently without significant noise coupling occurring between the electrical amplifiers through the power distribution network. The electrical data signal is then converted to an optical data signal for transmission to a second module. The optical data signal is transmitted to the second module through an optical path where it is optically amplified. The amplified optical data signal is then received at the second module and detected to produce an electrical signal which has a substantially improved signal-to-noise ratio.

摘要： Efficient immutable syntax representation with parent pointers under incremental change is enabled by creating a data structure comprising at least one tree structure that allows both upward and downward references in the tree and a tree structure that is immutable (read-only), and allows parts of itself to be re-used in other data structures. The data structure described enables tools to search and target particular sub trees. The fragment of the tree representing the targeted sub tree is produced as it is used. The rest of the tree is not produced. The read-only tree retains relative information, allowing it to be reassembled and shared.

摘要： An apparatus selectively transmits light in one of two orthogonal polarizations in an optical fiber. The apparatus has a facing surface formed at one location on the fiber to expose the evanescent field of an optical signal in the fiber. A nematic liquid crystal is placed in contact with the facing surface so that it is in communication with the evanescent field of the optical signal. The nematic crystals have a first orientation state which presents a first refractive index to light traveling in one polarization and a second refractive index to light traveling in the other polarization. The light traveling in one polarization is well guided while the light traveling in the other polarization is radiated at the facing surface. Thus, only light of one polarization continues to propagate through the fiber. The nematic crystals have a second orientation state in which the relative refractive indices for the two polarizations of light are changed so that the polarization which was originally well guided is radiated at the facing surface and the polarization which was originally radiated is well guided. The change in the orientation states of the nematic crystals is accomplished by applying an electric field between two electrodes so that the nematic crystals align themselves with the electric field.

摘要： When writing code, data structures that include inferred symbols are created based on usage of undefined symbols. As the user continues writing code, code model can be updated to represent updated information based on a learning model. Data structures including inferred symbols can be used by software development tools to provide developer help for symbols that are not yet created or are not yet bound. Inferred symbols can be visually distinguishable making the appearance of the inferred symbol information differ from actual symbol information. The appearance of information based on inferred symbols can be included within tools by activating a particular mode in a programming environment. Conversion of the inferred symbol to a real symbol may trigger the automatic compiler-generation of additional source code by a background compiler. Inferred symbols may be converted to actual symbols by activation of an option to make an inferred symbol a real symbol.

摘要： A consume-first mode for an editor is automatically entered if one or more predefined heuristic conditions are met. Some examples of heuristic conditions include conditions indicating that a user will be entering computer program source code during test-driven development, user action to undo autocompletion, and expected entry of a dynamically typed item identifier. In addition to heuristic consume-first mode, some editors recognize an explicit command to enter or exit the consume-first mode. A list of completion suggestions may be displayed in the consume-first mode, but autocompletion is turned off. An identifier may also be preemptively included on a suggested completions list for use before a user has entered that identifier using the editor.

摘要： A method and apparatus for constructing an optical wavelength-routing network in which each network node is a dynamic add-drop multiplexer (OADM) with minimized spectral filtering effect on pass-through channels and survivability upon power failure. By using cascaded tunable reflection filters as the building blocks, strictly add-drop non-blocking OADMs for single input/output fibers, double input/output fibers, and 3 input/output fibers can be constructed for application to unidirectional and bidirectional ring networks and mesh networks of arbitrary degree. Methods and apparatus for minimizing various types of out-of-band and in-band crosstalk occurring within the dynamic OADMs are also described.
