"Signal Transporter" LTX-7215

Signal TransporterFeatures

 The LTX-7215 Bidirectional Fiber Optic Link multiplexes one analog signal along with up to 4 independent TTL/CMOS/LVTTL digital channels to over 10 kilometers with a single fi ber.

 The incoming analog data is digitized to 12 bit precision at 100 mega samples per second and the digital channels operate at data rates of 0 to 50Mb/s. This is then transmitted at 2 Gb/s second for distances up to 10 kilometers.

 The digital signal is then received and the analog signal is accurately reproduced at the far end of the fibre optic link.

 The analog signal bandwidth may be from DC to 25 MHz (-3dB).

 The LTX-7215 has input voltage ranges of ±1 Volt or ±5 Volts.

 The input impedance of the analog channel may be set to 50 ohms or 1 megohm (75 ohms is optional).

 The LTX7215 series has a battery option that will allow for up to 3 hours of operation for experiments at extremely high potentials.

 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.
