Class 398: Optical Communications
This class provides for all types of communication systems in which optical signals are used to transmit modulated carrier wave information between points. Such communication includes transmitting an intelligence-bearing signal from one point to another in the form of variations in a characteristic of the light wave. The communication may be through free space, fibers or waveguides. These are used to transfer the information with an optical beam, and this beam can be used in various communication schemes to enable the most effective or desired method of moving the information, including optical multiplexing when plural information signals or plural transmitters and receivers are utilized.Subclass 161: Using delay
Class 341: Coded Data Generation Or Conversion
1) originating or emitting a coded set of discrete signals or 2) translating one code into another code wherein the information signal content remains the same but the formats may differ. For classification herein, at least one of the codes must be a set of pulses or digits and electrical in nature.Subclass 118: CONVERTER COMPENSATION
Subclass 120: CONVERTER CALIBRATION OR TESTING
Subclass 123: Having variable sampling rate
Subclass 127: Bipolar
Subclass 128: Dual slope analog to digital converter
Subclass 129: Plural slope analog to digital converter
Subclass 137: Using optical device, (e.g., fiber optics, cathode ray tubes)
Subclass 155: Analog to digital conversion
Subclass 156: Coarse and fine conversions
