摘要： A system is described that includes a system for correcting modal dispersion and errors in an optical fiber system. The system includes a multisegment photodetector coupled to an end of an optical fiber for detecting optical signals exiting the optical fiber and for converting the optical signals to an electrical output, the multisegment photodetector including a plurality of photodetector regions configured such that one of the plurality of photodetectors regions intercepts a mode in a manner distinct from another of the plurality of photodetectors. The system also includes logic configured to receive a resultant signal output from the photodetector regions and provide forward error correction decoding of the resultant signal.

摘要： Disclosed is a method that is useful in connection with providing discount factors for an exchange-traded mark-to-market derivative product that has a variable tick rate, such as an interest rate swap product. In some embodiments, the method includes providing a series of consecutive settlement values, which collectively represent a settlement value curve for the derivative product. The curve is evaluated by determining, for each consecutive pair of settlement values, whether the difference between the first settlement value in the pair and the second settlement value in the pair exceeds a threshold. The threshold represents the value at which a discount factor derived from said pair of settlement values, in conjunction with other parameters, would be negative. In other embodiments the disclosed invention encompasses an apparatus and a computer-readable medium.

摘要： Methods, systems and apparatuses are described for calculating a performance bond amount for a portfolio including interest rate swaps. A risk calculation module (or risk processor) may assist in the calculation. In some examples, values, such as swap (DV01) dollar values and volatility values, and adjustments/factors, such as calendar charge adjustments and liquidity charge minimums, may be used to enhance the margin calculation. These values may be maintained and updated in various ways, including but not limited to, lookup tables, matrices, and other structures. The margin calculations may be used by an exchange or clearinghouse to request a portfolio holder to deposit additional funds towards a performance bond associated with the portfolio.

摘要： Methods are provided to determine a settlement price for an over-the-counter exchange traded financial instrument. The method includes receiving swap curves from a plurality of market makers and identifying missing data points in the curves. A repair mode may be determined for curves identified as missing data. The curves may be repaired based on the determined repair mode. The selected curves including the repaired curves may be blended together to derive a final settlement prices for each of a plurality of standardized centrally cleared swaps. The financial instruments may include Euro denominated interest rate swaps, U.S. denominated interest rate swaps, or OIS interest rate swaps.
