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.
