Altimeter RF Over Fibre Optical Delay Line System

RFOptic's high frequency Altimeter Optical Delay Line (ALT ODL) provides a high-performance solution for testing and calibration of radar altimeter systems. The RF input signal is converted into a modulated optical
signal, which is then transmitted into a single mode fibre, creating a fixed time delay defined by the fibre length corresponding to a desired altitude. After passing through the fibre, the optical signal is converted back into an electrical RF signal, identical to the input RF signal.
The ALT ODL can be configured to emulate a single altitude or
up to 4,096 altitude steps. RFOptic's ODL unit is a compact solution, which provides superb signal performance and altitude simulation accuracy with an ultra-silent operation.
The control and monitoring is done using a front panel, a navigation switch, and a LCD display, or via a USB connection using RFOptic’s configuration tool software. USB API is available for automated testing applications as well as Ethernet remote management with RFOptic’s HTML/SNMP/REST remote management solution.
The Altimeter ODL offers very high accuracy up to 0.3ns for altitude steps under 2mand > 0.1% above. The maximum altitude can reach 30km in one enclosure.
