The FOD652-a-b-c from YOFC is an Optical Delay Line that has a delay range of 0.1-280 μs. It has a delay accuracy of ±0.01 μs at 0.1-10μs & ±0.1% at 10 - 280 μs and an insertion loss of 0.1 dB. This delay line uses optical fiber & fiber process technology to achieve high-precision true time delay and different levels of resistance from radiations. It has a customizable connector and small diameter fiber that can reduce volume. This optical delay line is available in a module that measures 152.4 x 152.4 x 100 mm and is ideal for radar monitoring/calibration, signal processing, phased array antenna, and phase noise processing applications.
