Measuring the polarization rotation due to the Faraday effect is the basic principle of Fiber Optic Current Sensors (FOCS) and Optical Current Transformers (OCTs).

With a growing need for higher power telecommunications amplifiers, learn about how doped fiber designs have evolved to handle higher pump power and signal power levels.

To mini or to micro, that is the question. Learn about the different types of Erbium Doped Fiber (EDF).
