Optical-electrical converter LTX-5520 series

signalTTLsingle-mode

Features • Transmits 16 independent TTL signals over a single fibre • Each channel has 0 to 25 Mb/S bandwidth • Inputs accepts LVTTL and/or CMOS/TTL • Outputs are LVTTL (0 - 3.3 V) • 850 nm version for multimode links up to 500 M • 1310 nm version for SM links up to 10 KM • May be paired with elements of the LTX- 5510 system to configure remote high speed 12-bit A/D and D/A converter modules The LTX-5520 enables the conveyance of sixteen independent channels of digital information over fibre optic links ranging from metres to more than 10 kilometres. Each of the 16 incoming TTL channels is sampled at 50 mega-samples per second, multiplexed and transmitted serially over an optical fibre at a 1 Gb/s data rate. 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 - 25 Mb/S. Two models are available. Selection depends on the fibre type and the length of the fibre optic link that is required. The LTX-5520-850 transmits at 850 nM over multimode fibre optic links of up to 500 metres in length, while the LTX-5520-1310 transmits at 1310 nm over single-mode fibre to cover distances in excess of 10 kilometres. The LTX-5510 precision analogue fibre optic link was the first in our series of “Signal Transporters”. It digitizes an analogue signal at a 50 Ms/S rate with 12-bit precision and reconstructs it 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 fibre-coupled 12-bit data acquisition system.
