Filed:

Jan 10, 2002

Appl. No.:

10/045870

Inventors:

Sumit Verma - Sunnyvale CA, US
Mark Selker - Mountain View CA, US

Assignee:

Finisar Corporation - Sunnyvale CA

International Classification:

G06F 17/10

US Classification:

703 2, 398 24, 398202

Abstract:

The present invention describes the method and system for characterizing optical receivers based on the measured impulse response and by applying linear system theory. In a first embodiment, the impulse response of an optical receiver is obtained. Convolving the impulse response with band-limited input pulses (modeled with straight-line edge pulses), a receiver output pulse can then be determined. From this pulse, an associated eye diagram can be mathematically derived and the maximum ISI can be estimated. In a second embodiment, for a given input pulse stream with a specified amount of noise, the impulse response-generated eye diagram is used to estimate the bit error rate (BER) that the receiver would yield.

Appl. No.:

11/702861

Inventors:

Barbara Paldus - Woodside CA, US
Mark Selker - Los Altos CA, US

International Classification:

G01N 33/48

US Classification:

702 19

Abstract:

A method for converting non-linear optical loss readings in a bioreactor process vessel into process parameter units by applying a curve fitting algorithm to the fitting function represented by the empirical equation:wherein xis in the process units (PU), yis optical loss in the chosen units, A is the offset, D is the absorption coefficient, B is the effective scattering coefficient, and C is the scattering constant. The preferred fitting algorithm is Levenberg-Marquardt.
