An electrical/optical-optical/electrical converter pair has been announced by Terahertz Technologies Inc. The LTX-5515T digitizes an analog input signal to 12-bit precision with four auxiliary digital inputs and transmits the data over a 2-Gb fiber optic link. The LTX-5515R receives the data and precisely reconstructs the five signals at the far end of the link. The transmitter has selectable input ranges of ±1 or ±5 V, and input impedances can be set to 1 MΩ or 50 Ω. Overall system bandwidth is DC to 25 MHz. Applications include data acquisition and transmission for plasma physics experiments, power transmission equipment, test chambers and video transmission.
