Abstract
A data transmission link including a transmitter for acquiring conducted electrical data and transmitting electromagnetic radiated wave data such as optical data corresponding to the conducted electrical data, a receiver for receiving the electromagnetic radiated wave data and generating conducted electrical data corresponding to the radiated wave data and at least one wave conduit such as fiber optic data transmission cable for transmitting the radiated wave data from the transmitter to the receiver is disclosed. In one arrangement, the transmitter includes a light emitting device which is driven by an output driver responsive to the electrical data accepted by an input gate. In an optical data transmission link, the receiver includes a preamplifier for receiving optical data and generating bipolar electrical signal data corresponding to the optical data, a postamplifier for amplifying the bipolar conducted electrical data generated by the preamplifier, and an output stage for acquiring the amplified bipolar electrical data from the postamplifier and generating single-ended conducted electrical data corresponding to the bipolar electrical data. The optical data transmission link i…
