The AFODa-b-c-d-e/e from YOFC is an Optical Delay Line that operates at a wavelength of 1310 nm and 1550 nm. It has a frequency range from 100 MHz to 18 GHz and dynamic range of 98 dB·Hz^2/3. This optical delay line has a delay range of 2 µs - 128 µs and delay step of 2 µs. It has a delay accuracy of 1% and switching time of up to 2 ms. This optical delay line has a dynamic range of 98 dB-Hz and noise figure of up to 48 dB. It has an amplitude flatness below ± 3 dB and a 1 dB input compression greater than 15 dBm.

The AFODa-b-c-d-e/e has a progressive delay number (blade module number) of 6 and an RF gain of -20 dB (at 128 µs). It is compatible with FC/APC & SMA connectors and can be controlled via RS232 & Ethernet interfaces. This optical delay line requires an AC supply voltage of 220 V and is available in a 3U standard package. It is ideal for radar system testing, phased array antennas, phase noise testing, signal processing, and test & calibration lab applications.
