Fiber-Optic Communications

Measurement data is transmitted through state-of-the-art fiber-optic cables. The benefits are numerous compared to other forms of data transmission.

  • Fiber-optics are immune to electrical interference
  • Minimal attenuation of light through fibers
  • Fast messaging over enormous distances
  • Radiation hard fiber materials


Our new products will sometimes replace older ones. We call these older devices "legacy". Although we still make legacy devices, we no longer recommend using them in new designs.

We will continue to support legacy products with software and hardware fixes.

Control Systems

Pyramid devices are modular and pefect for distributed control systems. Easy to use software and networking make prototyping and integration rapid. Pyramid provides long term customer support and high reliability for final production systems.

Our devices can tolerate high levels of HF, RF and transient electrical noise. The real time fiber optic communications between controllers and front-end devices are completely immune to electrical interference. Fiber optics can also span voltage gaps of hundreds of kilovolts. An example application is control of the power supplies in the the high voltage terminal of an accelerator ion source.
