Description of the device
4.3 Interfaces and signaling contact of the switches
SCALANCE X-300
Operating Instructions, 02/2012, A5E01113043-12
91
4.3.2 Ethernet interfaces - optical ports
4.3.2.1 1000Base-SX
Transmission rate
The transmission rate of the optical gigabit ports is 1 Gbps.
Transmission mode
Transmission with 1000Base-SX is defined in the IEEE 802.3z standard and is specified as
1000 Mbps transmission rate and full duplex.
Transmission medium
Data is transmitted over multimode FOC. The wavelength is 850 nm.
The core diameter of the multimode FOC is 50 µm; the light source is an LED. Many modes
(light beams) are used for signal transmission. The propagation times of the light pulses
(dispersion) restrict the maximum range considerably.
Transmission range
The maximum transmission range (segment length) is 750 m when using SIMATIC NET
fiber-optic multimode FOC with SC duplex connectors.
Connectors
SC duplex female connectors are used.
On the IE Switches X-300EEC, devices are connected via LC jacks.
4.3.2.2 1000Base-LX / 100Base-FX
Transmission rate
The transmission rate of the optical gigabit ports is 1 Gbps.
Transmission mode
Transmission with 1000Base-LX is defined in the IEEE 802.3z standard and is specified as
1000 Mbps transmission rate and full duplex.
