3.13.3 SCALANCE X212-2 FO ports
Transmission speed
The transmission speed of the optical Fast Ethernet ports is 100 Mbps.
Transmission mode
The transmission mode for 100Base-FX is specified in the IEEE 802.3 standard.
Since the full duplex mode and the transmission rate cannot be modified for optical
transmission, autonegotiation cannot be selected.
Transmission medium
Data transmission is over multimode fiber-optic cable (FO cable). The wavelength is 1310
nm.
Multimode fiber-optic cables are used with a core of 50 or 62.5 µm; the light source is an
LED.
The outer diameter of the FO cable is 125 µm.
Transmission range
The maximum transmission range (segment length) is up to 5 km depending on the cable
type.
Connectors
The cables are connected over BFOC sockets.
