Word-Width Digital Fiber Optic Links LTX-5520

Source: Terahertz Technologies Inc.
The LTX-5520 "Signal Transporter" Converter pair is designed to transmit 16 independent digital signals to a remote location via fiber optic cable. These products simultaneously samples all 16 input channels at 50 Ms/S, converts them to a serial format, transmits the data over a Gigabit fiber link and converts the signals back to a parallel format at the receiving end of link. The primary applications are those situations in which the signals of interest have a high common mode voltage with respect to the measurement equipment. These applications include plasma physics experiments, EMC test chambers, power transmission equipment, and high power laser equipment.

The Word-Width Digital Fiber Optic Links LTX-5520 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 5 x 107 times per second, multiplexed and transmitted serially over an optical fiber at one 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 - 25 Mb/S.

Two models of the Word-Width Digital Fiber Optic Links are available. Selection depends on the fiber type and the length of the fiber optic link that is required. The LTX-5520-850 transmits at 850 nM over multimode fiber optic links of up to 500 meters in length, while the LTX-5520-1310 transmits at 1310 nm over 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.
