LSAOL 1.0, Laser-Powered RF Link, 9kHz - 6GHz w/5-12VDC 2W power source

The LSAOL 1.0/1.1 Laser-Powered Analog Optical Links with integrated pre-amplifiers are low-noise RF signal transmission systems for 9 kHz to 6 GHz.

They are ideally suited for EMC emission testing. The need for batteries is eliminated through laser-powered operation.

LSAOL 1.0/1.1 consist of a Front Unit and a Base Unit. The signal is picked up by the Front Unit, transmitted optically, and converted back to an electrical signal by the Base Unit, which is typically analyzed using an EMC test receiver.

The LSAOL Front Unit is laser-powered and equipped with both low and high-band pre-amplifiers, which can be turned off. LSAOL 1.0 provides an adjustable, 5 V to 12 V phantom power supply delivering up to 2W to external devices such as active antennas or pre-amplifiers.

When combined with the LUMILOOP LSMux 12:2 RF Multiplexer, up to 12 LSAOL 1.0/1.1 Analog Optical Links can be operated concurrently for parallelized high-throughput automotive EMC testing.
