Optical Delay Line (ODL) modules

High Performance Optical Delay Line solutions for testing and calibrating radar systems and RF communications.

Optical Delay Line is an electric-optic device that performs fixed time delay(s). The time delay is between few nanoseconds up to several hundred microseconds. By varying the distance that light travels, the delay time can be controlled.

The ODL module converts analog RF signals to optical signals and back at 0.1-20 GHz range. A fixed time delay is defined by the fiber length.

The RF Delay Line module operates as a standalone unit with no need for any intervention by the operator. It is also controlled by a laptop through various communication interfaces.

RFOptic’s Optic Delay Line module is a compact ODL unit. It provides superb performance including accurate time delay and with ultra silent operation.

The ODL module can be provided with an integral switch unit. It supports up to 8 predefined time delay values in a single ODL unit.
