Electric optical fiber delay lines (ODLs) are critical components in modern precision engineering, vital for applications ranging from radar calibration and satellite communications to optical coherence tomography and phased-array systems. By translating physical fiber length adjustments into precise, programmable time delays, these devices offer unmatched accuracy. However, deploying an electric ODL into a larger system involves complex optical and mechanical interfaces. https://www.cq-smart.com/electric-optical-fiber-delay-line
