摘要： A burst mode digital data receiver automatically adjusts its logic reference voltage to be equal to one-half of the sum of the minimum and maximum excursions of a received data signal. The receiver includes a differential amplifier circuit which has a first input for receiving the data signal and a second input connected to a voltage reference circuit. The voltage reference circuit is responsive to an output signal from the amplifier circuit to produce the required logic reference voltage at the second input to the amplifier circuit by generating a feedback signal which causes the amplifier circuit to have a first gain value during the absence of the data signal and while the data signal is less than its peak amplitude and a second gain value approximately twice the first gain value for a predetermined time after the peak amplitude of the data signal is reached.

摘要： Disclosed is an optical package including at least one electro-optical component aligned with at least one optical fiber. The electro-optical component is mounted on a surface which is essentially parallel to, but not coplanar with, the longitudinal axis of the fiber and light is coupled between the fiber and component by bending the light path. Electrical connection to the component is provided by conductors mounted over the same surface, thus producing a compact package. The invention is used preferably with arrays of components and fibers to eliminate the need for a vertical fanout to contact the components.

摘要： A digital burst mode communication system operates at a fixed wavelength for transmission and reception of burst mode signals using a pair of transceivers and a single optical cable. The stray noise level in the system is significantly reduced by use of angled plate absorbers that receive scattered transmission burst signal from a 45 degree partially reflecting mirror. Use of transparent glass ferrule with or without a front surface anti-reflection coating instead of an opaque ceramic ferrule to support optical fiber at a selected location within the transreceiver reduces optical detector signal noise. Isolation of received burst signal from transmitted burst signal is increased to better than 30 dB. The system operates by sending only data bits across the single optical cable without scrambling or encoding preambles, significantly improving the efficiency of high speed communication.
