LTX-552X Digital Fiber Optic Link
Features:
● Channel capacity up to 50 Mb/S
● Outputs are LVTTL (0 - 3.3 V)
● Accepts LVTTL and/or CMOS/TTL inputs
● 1310 nm version for SM links up to 10 KM
● 850 nm version for multimode links up to 500 Meters
● Transmits 16 independent TTL signals over a single fiber
● Paired with LTX-551x to configure remote high speed 12 or 14-bit A/D and D/A converter modules
The LTX-552x conveys sixteen independent channels of digital information over a fiber optic link ranging from meters to more than 10 kilometers.
Each of the 16 incoming TTL channels is sampled at up to 5 x 107 times per second, multiplexed and transmitted serially over an optical fiber at up to 2 gigabit per second. The receiver acquires this digital data and de-multiplexes it to 16 separate output ports. Each of these channels may be toggled at rates ranging from 0 to 48 Mb/S.
Two models are available. The LTX5520 transmits serially at 1 gigabit and the LTX5525 transmits at 2 gigabit over either SM or MM fibers. The distance between units determines the fiber required to complete the link. 850 nm units operate on multi-mode fiber up to 500 meters in length, while 1310 nm units operate with single-mode fiber to span distances exceeding 10 kilometers.
The LTX-5510 precision analog fiber optic link was the first in our series of “Signal Transporters”. It digitizes an analog signal at a 50 Ms/S rate with 12-bit precision and reconstructs the signal at the LTX-5510 receiver by means of a fast D/A converter. If the user employs the LTX-5520 receiver with the LTX-5510 transmitter, the result is a remote fiber-coupled 12-bit data acquisition system.
Similarly one can employ the LTX-5520 transmitter with the LTX-5510 receiver to generate fast high-resolution analog signals at a remote location.
Applications include data acquisition for plasma physics experiments, signal transmission and control of equipment at high voltage potentials, operation through Faraday shields, and precise noisefree signal transmission in hostile EMI environments.
