Overview

OPTICAL-to-ELECTRICAL CONVERTER

It has always been difficult to transport fast logic signals long distances over copper conductors. Coaxial or twisted-pair transmission lines introduce attenuation, dispersion, ground loops, and provide entrée for external electrical noise. The result can be jitter, pulse width distortion, and ultimately logic errors.

A J720/J730 combination can transport a logic level or critical timing triggers over kilometer distances in high EMI environments with link jitter typically below 12 ps RMS. The J730 provides a digital logic output with risetime below 750 ps, and a fast analog (180 MHz bandwidth) output is also provided for monitoring link integrity.

The J730 is compatible with the Highland J720 and J724 E/O Converters, the model P400 Digital Delay/Pulse Generator, the company's VME-packaged electrical/optical converter products, and its other VME modules with optical I/O.

Features

• Compact logic-lvel optical signal link receiver
• Allows transport of logic levels and fast triggers over long distances in high EMI environments
• Fast electrical rise times
• Below 12 picoseconds typical RMS link jitter
• J730-1 uses commonly-available 62/125 micron multimode ST-connectorized fiber at 850 nm
• J730-3 and J730-5 uses singlemode or multimode fiber at 1310 and 1550 nm
