Description of the device

3.4 FO port (fiber optic)

3.4 FO port (fiber optic)
NOTICE
Failure of the data traffic due to contamination of optical plug-in connections
Optical sockets and plugs are sensitive to contamination of the end face. Contamination
can lead to the failure of the optical transmission network.
Close unused optical sockets and plugs as well as pluggable transceivers and slots with the
supplied protective caps.
Remove the protective caps only immediately before you use the plug-in connection.

SCALANCE X101-1

Transmission speed
The transmission speed of the optical Fast Ethernet port 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 speed cannot be modified for optical
transmission, autonegotiation cannot be used.
Transmission medium
Data transmission is via multimode fiber-optic cable (FO cable). The transceiver wavelength
is 1300 nm.
Multimode FO cable is used with a core diameter of 50 or 62.5 µm. The light source is an
LED.
The outer diameter of the FO cable is 125 µm.
Range
The maximum transmission range (segment length) is as follows:
● with 62.5/125 µm fiber multimode SIMATIC NET cable: 4 km
● with 50.0/125 µm fiber multimode SIMATIC NET cable: 5 km
Connectors
The cables are connected using BFOC sockets.
