Optical Delay Line Solution
More Flexible and Reliable ODL Modules
Optical Delay Line (ODL) is an instrument to prolong the signal on purpose from one end to the other end, it converts the RF signal to optical signal and propagate a predetermined length of fiber and finally the optical signal is converted to RF signal.
When an optical light is passing through a series of optical switches, the selected delay signal can then be performed and controlled.Using up to 12 predefined time delay values in ODL units that configure up to 4,096 delay combinations. It is quite suitable tool for a Radar testing, remote radar calibration and Radar for automotive testing purposes.
Zequn Technologies can offer a wide range of delay time, from nanosecond to microsecond with different RF frequencies, from 3GHz to 40GHz. We are good at controlling the accurate timing. The Delay Accuracy is within 0.5ns. We can also provide an additional function for dynamically adjusting the in-line output Gain with great accuracy.
