Mini ODL Series

RFOptic’s Mini Optical Delay Line (ODL) series provides a compact, high performance solution for testing and calibrating radar systems or for RF Communication featuring accurate time delay with ultra low noise. The Mini ODL solution up to 6 GHz  is based on direct modulation, while the Mini ODL solution from 6 GHz up to 18 GHz are based on indirect modulation.

As with all other RFOptic’s ODL solutions, the ODL unit 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 also be controlled externally from a PC through RS232 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 silent operation. The ODL can be purchased with an integral switch unit supporting up to 8 predefined time delay values in one ODL unit.

For some applications, RFOptic offers its Mini ODL solution up to 6 GHz  based on direct modulation. Mini ODL is also available up to 18 GHz on indirect modulation basis.
