Abstract: An electro-optic interface system (100) configured to communicate, via an optical channel, an electronic signal between a first (110) and a second electronic system (120) includes a first electro-optic transceiver (130), an optical channel and a second electro-optic transceiver (140). The first electro-optic transceiver (130) includes a signal port coupled to the first electronic system (110) and an output coupled to the optical channel and includes a first transceiver emulator circuit (216), and a first transceiver laser (252). The first transceiver emulator circuit is configured to receive an electronic signal (260) comprising parallel data from the first electronic system (110) and, in response, produces serialized data. The first transceiver laser (252) produces a first modulated output signal corresponding to the electronic signal communicated from the first electronic system (110). The first electro-optic transceiver (130) communicates with the laser (250) to determine the operating characteristics and further analyses the returned signal (260b), wherein a processor within the drive controller (230) makes a determination of whether an adjustment in the operating characteristics of the laser (250) would result in improved performance of the optical link. The drive controller (230) dynamically alters the operating characteristics of the laser (250) if the determination is positive. The second electro-optic transceiver (140) includes a first port coupled to the optical channel and a second port coupled to the second electronic system (110). The second transceiver (140) includes a second transceiver photodetector, and a second transceiver emulator circuit. The second transceiver photodetector is configured to receive the first modulated output signal emitted by the first transceiver laser and, in response, produces a first received signal. The second transceiver emulator circuit is configured to receive the received signal comprising serialized data and to produce in response parallel data.

Abstract: A controller (320) for controlling various operational parameters of the Laser Module (303). The modulation drive signal (300) causes the circuits in the driver (301) to send a signal to the output (302) so that the laser can send an optical power output (304) proportional to the drive signal (300). The control methods in Laser Controller IC (320) consist of control algorithms embedded in firmware. The Laser Controller IC (320) includes support circuits for control of a laser. Some of the distinguishing features in the present invention are 1) feedback information from the sensors is obtained in a synchronous manner as a snapshot of the laser performance, and 2) algorithms handle the entire set of controls in firmware. The algorithm feature allows for advanced servo controls, which precisely stabilize the laser, can accommodate adaptive controls, and can be leveraged from one laser transmitter design to another.

Abstract: The invention presents a method that calibrates the laser optical power (202) in a continuous manner without disrupting the flow of information in the optical communications link. The method utilizes knowledge of the measured value of the laser optical power (202) and makes necessary adjustments to optimize the values of the Extinction Ratio, Bit Error Rate and to compensate for aging. The method utilizes knowledge of the temperature from a sensor (114) and mathematical models, which contain parameters which are updated for a specific laser configuration.

Abstract: The present invention provides an electro-optical isolation system (10) for coupling an electronic measuring device to a device under test (12) for making accurate measurements of signals within a wide frequency range while the device under test (12) is being subject to high power electrical disturbances (14, 16). The invention provides an increased rejection of high common mode signals and reduction of undesired self-capacitance by implementing a shielded handheld transmitter unit (18) having an integrated measurement probe (24). The transmitter unit (18) converts the sensed signal to an optical signal which is transmitted through an optical medium to a receiver unit (22). Under control of a microprocessor (116), the level of the output signal from the transmitter unit (18) is modulated by the signal received from the sensing probe (24). The microprocessor (116) within the transmitter unit (18) automatically controls the level of optical signal (126) emitted by the optical converter (124), and further calibrates a driver circuit (134) to maintain measurement accuracy. The modulated optical signal (126) emitted by the electro-optical converter (124) is communicated to the receiver unit (22) by an optical fiber medium (20a or 20b).
