"Signal Transporter" LTX-5510

Signal TransporterFeatures

Transmits analogue and digital signals simultaneously

DC to 12.5 MHz analogue bandwidth

Two input ranges, +/-1 V and +/-5 V

Analogue signal digitised to 12 bit precision

Four independent digital channels

DC to 20 MHz digital bandwidth

 The LTX-5510 enables precise conveyance of analogue plus four channels of digital information over fibre optic links ranging from meters to more than 10 kilometers.

 Incoming analogue data is digitised to 12-bit precision at 50 mega-samples per second and transmitted over optical fibre at a 1 Gb/s data rate. The receiver acquires this digital data and accurately reconstructs the analogue signal at the far end of the fibre optic link.

 The analogue signal bandwidth is from DC to 12.5 MHz (-3 dB). Two input voltage ranges are provided, +/-1 V and +/-5 V. The input impedance of the transmitter analogue channel may be set to 50 ohms or 1 megohm (75 ohms is optional).

 Multiplexed along with the analogue data are four independent TTL/CMOS/LVTTL digital signals that may be toggled at rates in excess of 20 MHz.

 Two models are available. Selection depends on the fibre type and the length of the fibre optic link that is required. the LTX-5510-850 transmits at 850 nm over multi-mode fibre optic links of up to 500 meters in length, while the LTX-5510-1310 transmits at 1310 nm over single-mode fibre to cover distances in excess of 10 kilometers.

 Applications include data acquisition for plasma physics experiments, signal transmission and control of equipment at high voltage potentials, transmission of high quality video, and precise noise-free signal transmission in hostile EMI environments.
