 Features
 |
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.
