Optical Delay Line

The ODL module convert RF signals to optical signal and back, performing a desired time delay of input RF signals at 0.1-15 GHz region (20GHz is optional).
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. After passing the fiber, the optical signal is converted back into an electrical RF signal.
ODL modules with time delays between 0.01 to 200 µsec can be provided to customers. The electrical control on the ODL is done automatically by a PC, with no need for any intervention of the operator.
ODL modules are a turn key solution, which provides superb performances including accurate time delay, no RF attenuation after conversion, -80dBm spurious, and with an ultra silent operation. The ODL modules can be purchased with severed predefined time delay values.

• 20 GHz ODL
• ODL with up to 8 different delays
