Abstract: An opto-electronic contact, method and connection system can utilize an active opto-electronic converter configured for removable optical engagement with an opposing contact. A barrel housing defines an interior cavity to capture the converter in the interior cavity for external optical engagement to the opposing contact via the first barrel opening for relative movement of the converter axis along the elongation axis, transverse thereto, and oblique thereto to accommodate mating tolerances responsive to engaging the opposing contact. A flexible circuit board assembly can be used to externally electrically interface the converter.

Abstract: A panel mount connector and method involve a connector shell assembly that is configured to be received in an opening that is defined by a panel with the connector shell defining a through passage. A flexible circuit board is supported within the through passage and defines a first external connection interface at one end for external electrical access from one side of the panel when the connector shell assembly is installed in the panel and at least the first external connection interface is supported for independent movement relative to the connector shell.

Abstract: A receiver assembly for use in an optical telecommunications network is provided that automatically generates a reference level for the incoming signal burst based on its preamble without the need to pre-process the entire signal burst. The entire signal burst is fed directly from the TIA into the input of the limiting amplifier. A differential amplifier, tapped from the data and data bar outputs of the limiting amplifier, samples the signal stream to capture the preamble portion of each signal burst. The preamble portion of the signal burst is then passed, post amplification, into a sample and hold circuit. The sample and hold circuit samples the amplitude of this preamble portion of the signal and then holds the sampled level for use as a reference level for the processing of following payload signal.

Abstract: A passive optical network which is capable of full duplex digital transmission at high data rates and which also provides analog broadcast transmission is disclosed. A central station provides analog broadcast transmission at a first wavelength of light and full duplex digital transmission using second and third wavelengths of light. Optical networking units, electrically or wirelessly coupled to end users in the network, are optically coupled to the central station via passive optical network nodes. The optical networking units resolve the two broadcast streams from the central station employing compact optics configured on a transparent substrate and provide burst mode digital transmission up stream to the central station on a time division multiple access basis.

Abstract: A fiber optic transmitter and/or transceiver adapted for use in an optical fiber data transmission system which is capable of transmitting data at high data rates in burst mode is disclosed. An analog dual loop automatic power control circuit samples monitored laser power peak and valley levels and uses them for modulation and bias laser driver control. These levels compensate for variations in laser power due to temperature variations or other factors. The sampled peak and valley levels are held between bursts in an analog level memory and are reestablished on a burst by burst basis. The optical transmitter or transceiver is further capable of operating in both burst and continuous modes.
