"Signal Transporter" LTX-5525

Signal TransporterFeatures

Transmits 16 independent TTL signals over a single fibre

Each channel may be toggled from 0 - 50 MHz

Inputs accept LVTTL and/or CMOS/TTL

Outputs are LVTTL (0 - 3.3 V)

850 nm version for multimode links up to 300m

1310 nm version for SM links up to 10km

 The LTX-5525 conveys sixteen independent channels of digital information over a fibre optic link ranging from metres to more than 10 kilometres.

 Each of the 16 incoming TTL channels is sampled 100 million times per second, multiplexed and transmitted serially over an optical fiber at two gigabits 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 - 50 MHz.

 Two models are available. Selection depends on the fibre type and the length of the fibre optic link that is required. The LTX-5525-850 transmits at 850 nM over multimode fibre optic links of up to 300 metres in length, while the LTX-5525-1310 transmits at 1310 nm over single-mode fiber to span distances exceeding 10 kilometres.

 The new LTX-5525 doubles the data capacity of our previous word-width digital fiber optic links. Paired with elements of our high-speed analog links, the LTX-5525 allows the user to configure remote precision A/D or D/A converters. This eliminates the need for the user to digitise analog signals at the receiving end of the analog data link.

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