)
*) 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.
Note
No autonegotiation
With optical transmission, the full duplex mode and transmission speed cannot be changed. For
this reason, the autonegotiation function cannot be selected.
