Radiation-resistant Optical Fibre Delay Lines

Taking advantage of optical fibre and fibre process technology, YOFC's radiationresistant optical fibre delay lines feature high-precision true time delay, and different levels of radiation resistant can be achieved. The experienced design have been proved with a high mechanical performance and environmental reliability. Small diameter fibre can be selected to reduce the volume for special application. Optical fibre and connector is customized.
