optoA2B, Fiber-optic, Automotive Link for A2B Signals

The optoA2B system is a robust solution for the optical transmission of A2B signals, designed to deliver high performance in EMI and EME test environments. The system comprises a master and a slave unit, both powered by internal batteries and interconnected via optical fiber. With its optical transmission capabilities and shielded casing, the optoA2B ensures reliable, interference-free signal transmission.

Key Features and Benefits

1. Reliable Optical Transmission:

   • Specifically designed for transmitting A2B signals via optical fiber.
   • Optimized for high-performance operation in challenging EMI and EME environments.

2. Portable and Flexible Design:

   • Battery-powered master and slave units offer portability and easy setup for versatile testing scenarios.
   • Optical fiber connection ensures high signal integrity.

3. Optional 19" Rack Integration:

   • One unit can be optionally integrated into a 19" rack housing for permanent setups.
   • Reduces setup time, minimizes error sources, and conserves workspace on the table.

4. Scalable Channel Capacity:

   • The 19" rack housing can accommodate up to eight communication links, including SENT, CAN, FlexRay, and more.
   • Channels can be added incrementally for future scalability.

The optoA2B system is an ideal solution for automotive and industrial testing environments requiring precise, interference-free transmission of A2B signals. Its scalable and compact design ensures it fits seamlessly into any testing setup.
