摘要： An optoelectronic device that has a network address (e.g., IF address) and participates in in-band traffic for purposes of performing functions (e.g., network diagnostics, network control, network provisioning, fault isolation, etc.) that are traditionally performed by host equipment. An embodiment of the invention may have a protocol engine and a status monitoring module. The protocol engine identifies data packets that are addressed to the optoelectronic device, and allows the optoelectronic device to insert packets of information generated by the device into in-band data. Logic of the optoelectronic device may modify the operating parameters of the device according to the control information included in the data packets. The status monitoring module detects the device's physical conditions and the conditions of its links. Status information generated by the status monitoring module may be incorporated into in-band data by the protocol engine such that the status information may be communicated to a host device or a remote device.

摘要： Systems and methods use single-fiber optical add/drop multiplexers (OADMs) to enable bi-directional data transmission in WDM systems over a single fiber. By reducing the required capacity for an optical network from dual fibers to a single fiber, significant cost and bandwidth efficiencies are achieved. The systems and methods also provide redundancy protection in single-fiber bidirectional line ring systems. In the event of a downstream fiber or device failure, the OADM module receives a signal on a first wavelength from a first direction, shifts the signal from the first wavelength to a second wavelength, and sends the signal back down the fiber it originated from on the second wavelength, thus maintaining the propagation of the signal in the ring system.

摘要： Semiconductor optical amplifier with polarization independent gain. A polarization adjusting layer is formed on a semiconductor optical amplifier. The semiconductor optical amplifier has an active region that includes both compressively strained and tensile strained quantum wells. The polarization adjusting layer is formed and then etched to a thickness that repositions an optical signal within the active region such that the gain of the optical signal is independent of the polarization of the optical signal.

摘要： A sensing system tethered to an optical fiber for delivering optical power. A sensing system has a semiconductor device that includes photodiodes and a laser. The optical signal delivered through the optical fiber generates a current in the photodiodes that can be used to at least recharge the sensing system's power supply or bias the laser. The optical signal can be modulated to deliver data to the sensing system. The laser can be modulated to transmit data from the sensing system over the optical fiber. Because the power source can be recharged, the sensing system can also transmit and receive using an RF module.

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.
