Fiber-optic systems
A signal out of an EMC chamber, unchanged.
The link carries an electrical signal over fiber from a source in a high electromagnetic field or an anechoic chamber to the monitoring bench outside. The modules are validated for EMC up to 200 V/m, 500 kHz to 18 GHz. Used in reverberation chambers, for bulk current injection tests, and for A2LA or AEMCLRP laboratory work.
- DC to 8 MHz
- analog bandwidth over fiber (FO-HBAVT/HBAVR)
- 1 to 2
- channels per link
- Analog · CAN · video

Light does not pick up a field.
The link replaces the copper between the equipment under test and the monitoring bench.
In an EMC test, a copper cable is an antenna: it changes the test and corrupts the signal. A fiber does neither, so the monitoring stays stable while the field is on.
Advantages
- The transmitterIt sits next to the equipment under test, inside the chamber, and converts its electrical signal into light. Its shielding protects it from EMI and EMP; it runs on 3 AA batteries.
- The fiberGlass carries no current. It neither picks up the field nor brings interference back into the chamber.
- The receiverIn the low-field area, it converts the light back into an electrical signal for your monitoring equipment. The links also work the other way, to source a signal into the equipment under test.
