Optical Delay Line (ODL)


Introduction


We offer Optical Delay Line (ODL) modules with time delays that vary between 0.01 and 300 μsec that can be controlled externally via a PC.

Our ODL modules are suitable for radar testing, radar calibration, electronic warfare and other defense applications – and is also a useful tool for telecommunications testing and simulating channel delay.

The ODL module adds time delay to the input RF analog signals at the 0.01-20 GHz frequency range. The RF input signal is then converted into an optical modulated signal, which is transmitted into a single mode fiber, creating a fixed time delay. At the other end of the fiber the optical signal is converted back into an RF signal (which is identical to the original signal).

The ODL compact modules provide accurate time delay, option for no RF attenuation after conversion, and -100dB spurious-free dynamic range, delivering superb performance and ultra quiet operation. Due to their flexible design, RFOptic ODL modules can be delivered with several switchable predefined time delay values.
