RFOptic’s 8GHz Optical Delay Line series provides a top performance solution for Testing and Calibration of Radar systems, or for RF communication.

The ODL converts analog RF signals in the 0.1-8 GHz range to optical signals and back. The RF input signal is converted into an optical modulated signal, which is then transmitted into a single mode fiber, creating a fixed time delay defined by the fiber length. After passing the fiber, the optical signal is converted back into an electrical RF signal, which is exact to the input RF signal.

Any fixed time delay between 0.1 and 300 μsec can be provided to customers. The ODL is operated as a standalone unit with no need for any intervention by the operator – it can be also controlled externally from a PC through various communication interfaces.

RFOptic’s ODL unit is a compact solution, which provides superb performance including accurate time delay and with ultra silent operation. The ODL can be purchased with an integral switch unit supporting up to 8 predefined time delay values in a single ODL unit. There are 4 basic configurations that are illustrated below.
