Optical Delay Line (ODL) 2 Boxes
RFOptic’s Optical Delay Line (ODL) 2 Boxes series provides a high performance solution for testing and calibrating radar systems or for RF communication.
The ODL converts analog RF signals at different frequency ranges to optical signals and back, utilizing direct or indirect modulation ODL architecture.
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 identical to the input RF signal.
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 RS-232 or Ethernet interfaces. RFOptic’s ODL unit is a compact solution, which provides superb performance including accurate time delay, low spurious emission level with ultra low noise.
The ODL can be purchased with an integral switch unit supporting up to 8 predefined time delay values in one ODL unit.
