Siemens SIPROTEC 5

Inputs for Optical Sensors for Arc Protection (via Module ARC-CD-3FO)
Connector type AVAGO AFBR-4526Z
Number of transceivers 3
Fiber type Plastic Optical Fiber (POF) 1 mm
Receiver
Maximum -10 dBm ± 2 dBm
Minimum -40 dBm ± 2 dBm
Spectrum 400 nm to 1100 nm
Attenuation In the case of plastic optical fibers, you can expect a path attenuation of
0.2 dB/m. Additional attenuation comes from the plug and sensor head.

NOTE
Current and voltage must not be connected at the same time to one measuring transducer input. Instead,
only connect either current or voltage. For EMC reasons, do not connect a line to an unused input (current
or voltage).
Use shielded cables.
