摘要： An optical signal return path system includes a transmitter having a sample clock generator for generating a sample clock and an RF signal receiver for receiving and converting an analog RF data signal into a first data stream of digitized RF data samples at a rate determined by the sample clock. Supplemental channel circuitry provides a second data stream. A multiplexor receives and combines the first data stream and second data stream, and an optical transmitter converting the combined data stream into a serialized optical data signal for transmission over an optical fiber. The second data stream may contain maintenance data reflecting an operational state of the transmitter. A receiver receives the optical data signal and recovers therefrom a digital data stream and an associated first clock having an associated first clock rate. The data stream is stored in a memory device at the first clock rate. A clock generator generates a second clock having an associated second clock rate that is adjusted in accordance with a clock control signal. A control circuit reads data from the memory device at a rate corresponding to the second clock rate and generates a fullness signal that indicates whether the memory device is more full than a predefined threshold fullness level. A clock speed adjusting circuit generates the clock control signal in accordance with the fullness signal.

摘要： Optical modules described herein include optical components such as lasers or photodiodes for communicating on fiber-optic networks. The lasers and photodiodes have analog interface such that the lasers and photodiodes can be controlled by a controller external to the optical modules. The optical modules also include memory modules. The memory modules store operating characteristics of the lasers and photodiodes. The operating characteristics can be read via digital interfaces that are connected to the memory modules. This allows the controller to appropriately adjust signals such that a randomly selected controller may be used with a randomly selected optical module.

摘要： A semiconductor optical amplifier for eliminating cross talk. The semiconductor optical amplifier includes a waveguide ridge that is formed on a broad area semiconductor laser. The ridge has angled facets and guides incident optical signals through the active region. When lasing, the broad area semiconductor laser locks the carrier density and photon density such that an incident optical signal does not affect the carrier density or the photon density. Thus, the broad area laser and the semiconductor optical amplifier share the same active region or gain medium and cross talk is eliminated when multiple optical signals are incident on the semiconductor optical amplifier.

摘要： A redundant optical signal transmission and reception system is disclosed to enable information exchange via an optical communications network without data loss in the event of optical transmitter or receiver failure. In one embodiment, the redundant optical signal system includes a primary transmission link comprising a plurality of optical transmitters and a multiplexor for modulating and combining electrical signals into a primary multiplexed optical signal. In the event of failure of an optical transmitter, a backup transmission link is activated to compensate for the malfunctioning transmitter. The backup transmission link utilizes a backup optical transmitter to modulate the electric signal formerly received by the malfunctioning optical transmitter. The backup transmission link combines the backup optical signal with the primary multiplexed optical signal to form a complete optical signal for transmission over the optical network. In another embodiment, a similar process is performed for providing backup optical signal reception.

摘要： A modular sensing system architecture. A sensing system includes multiple planes that are in electrical communication. A power plane provides a power source and a communications module that can be optical and/or electrical in nature. The power source can be upgraded using optical power delivered over an optical fiber. The sensing system can also both transmit/receive data over the optical fiber. A processing plane provides memory and processing power. The processing plane can be updated/upgraded via the communications module or the optical fiber. A sensor plane includes multiple sensors. The architecture enables sensor planes to be interchangeable while still having communication with other planes of the sensor. The processing plane can be updated to accommodate different sensor configurations.
