Model 6766R-KIT Four Channel TTL Logic-to-ST Fiber Interface Converter with DIN Rail Mounting Kit
Overview
The Model 6766R-KIT is a high speed TTL digital logic level to fiber interface converter from Electro Standards Laboratories. It translates four input/output logic pairs into four fiber pairs, resulting in a total of eight fiber optic connections. Typical operating speeds are up to 5 Mbps. Features include ESD protection on all copper interfaces, convenient ST fiber connectors, and logic test points that allow for signal monitoring. Provision for user selectable jumpers for fiber light ON/OFF polarity located on circuit board inside the Model 6766R-KIT enclosure.
DIN Rail mounting clip included for additional installation options. DIN rail mounting kit attaches to the bottom cover of the Model 6766R-KIT Fiber interface converter.

What is a TTL to Fiber Interface Converter?
TTL to Fiber Interface Converters are devices that translate electrical Transistor-Transistor Logic (TTL) signals into optical signals for transmission over fiber optic cable. This allows for the reliable transmission of digital signals over much longer distances and provides immunity to electromagnetic interference (EMI) and ground loops.
Why Use a TTL to Fiber Interface Converter?
TTL to Fiber Converters are designed to overcome the distance limitations and noise susceptibility of traditional copper wiring when dealing with TTL signals.
Common Applications for TTL to Fiber Converters include:
• Industrial Control & Automation Networks: Factories often need noise-immune communication between sensors, actuators, and controllers. TTL to Fiber Converters extend the reach of copper signals and reduce electromagnetic interference.
• Laboratory and Test Instrumentation Networks: Research environments often use TTL digital signaling for triggers, timing, etc., between devices and computers converting them to optical signals to avoid interference.
