*) Depending on the cable used:
● If you are using at least OM1 fibers (attenuation ≤ 1.5 dB/km, bandwidth length product ≥
500 MHz*km), you can reach a cable length of up to 3 km.
● When are using fibers with attenuation values ≤ 1 dB/km, you can reach a cable length of
up to 5 km.
You can find additional information in the "Industrial Ethernet / PROFINET Passive network
components" System Manual, see also section "Introduction", paragraph "Additional
documentation".
