Hi All,
I'm looking for a competitor of PPM Test Optical Link model Sentinel 3. It's a high performance transmission systems designed for test and measurement. Transmission of RF or DC over optical fiber to enables immunity to electrical interference (http://ppmtest.com/emc-emp-test-2/rf-over-fiber). Please, if you know some manufacturer or representative who sell or rent this kind of equipment, send me their contacts data.

Thanks in advance,
Regards,
