Fast Precision Analog Fiber Optic Link LTX-5515
The LTX-5515 "Signal Transporter" Converter pair is designed to transmit analog and digital signals to a remote location via fiber optic cable. This product digitizes the input signals at 100 Ms/s to 12-bit precision, transmits the results over a 2.0 Gb/s fiber link and reconstructs the signal at the far end. The primary applications are those situations in which the signal of interest has a high common mode voltage with respect to the measurement equipment. These applications include plasma physics experiments, EMC test chambers, power transmission equipment, and high power laser equipment.

The Fast Precision Analog Fiber Optic Link LTX-5515 enables the precise conveyance of one analog channel plus four digital channels of information over fiber optic links ranging from meters to more than 10 kilometers. This product digitizes the input signals at 100 Ms/s to 12-bit precision, transmits the results over a 2.0 Gb/s fiber link and reconstructs the signal at the far end.

Incoming analog data is digitized to 12-bit precision at 100 megasamples per second and transmitted over optical fiber at one giga-bit per second. The receiver acquires this digital data and accurately reconstructs the analog signal at the far end of the fiber optic link.

The analog signal bandwidth is from DC to 25 MHz ( -3 dB ). Two input voltage ranges are provided, ± 1 Volt and ± 5 Volts. The input impedance of the transmitter analog channel may be set to 50 ohms or 1 megohm (75 ohms is optional). Multiplexed along with the analog data, are four independent TTL/CMOS/LVTTL digital signals that may be toggled at rates of up to 48 Mb/s.
