RF & Microwave Fiber Optic Delay Line System

+1 626-293-3400
EMCORE’s variable (progressive) Fiber Optic Delay Line System
(DLS) oer superior performance for radar range calibration, ground-
based system tests, radar warning receivers, timing control, path delay
simulation, clutter canceller and phase shift discriminators. Delay
lengths of up to 2,000 µsec are available along with a wide range of RF
and optical performance options and packages.
The DLS provides convenient RF input / outputs that connect to an internal F/O
transmitter, optical ber, optical ampliers (EDFAs), optical switches and F/O receiver.
Internally, the RF signal is converted to an optical signal and transmitted over a ber
optic link to the receiver and provides the required signal delay time. Frequency range,
delay length, and link performance requirements can be tailored over a wide range of
performance levels to meet specic requirements. These options include RF amplica-
tion in the transmitter and receiver, as well as optical amplication for longer delays.
The DLS can be designed with either standard single mode or dispersion shifted
bers. Dispersion compensation bers are also available.
EMCORE’s DLS oers compelling size, weight and performance advantages over
traditional coax or waveguide solutions with the technical advantage of EMCORE’s
DLS delivering extremely low signal phase shift over temperature and time. This very
important feature has been achieved by using special mechanical design and ber
spools packaging. The system is supplied as a complete solution with all modules
mounted in 19” racks that use standard AC power. Packaging options include various
rack congurations and temperature stabilized optical ber.
