E/O Converter LTX-510


Two voltage input ranges

Two impedance settings

Transmit without conducting EMI

Bandwidth to >60 MHz (-3dB)

 The LTX-510 Electrical to Optical Converter is a convenient device that is intended to transmit analogue or digital signals to a remote location via a multi-mode fibre optic cable. The main applications are situations in which the signal of interest has a high common mode voltage with respect to the measuring equipment. These applications include plasma physics experiments, power transmission equipment and high power laser equipment. Trigger information from electrically noisy sources such as high current discharge laser systems may be transmitted, without conducting electro-magnetic interference (EMI), to the measurement equipment.

 The LTX-510 is intended for use with the TIA-500S Optical to Electrical Converter but can be used with other o/c converters that respond at 850 nm and have the appropriate responsivity and bandwidth. The input impedance may be set to 50 ohms for high speed signals sent over a transmission line or to 1 Megohm for use at lower frequencies. The input connector is a female BNC and the output connector is an ST style.
