Optical Delay Line

The Optical Delay Line (ODL) provides true time delay of wideband RF signals using a low loss optical fiber. The Input RF signal is converted to an optical signal, delayed by one or more single-mode optical fiber sections and is converted back into RF signal at the output. From the perspective of the RF signal, the ODL looks like a long distance wideband RF link with minimum loss and distortion. In its simplest form the ODL system has only one fixed delay section which is always engaged. A progressive ODL has an optical switching arrangement that is capable of cascading a number of fiber sections to deliver a range of many discrete delays.

Based on customer’s requirements we offer various ODL models

  • Single Delay Line
  • Multi Delay Line
  • Variable Delay Line
  • Multi Path Delay Line
  • Bidirectional Delay Line
