Description of the device
4.3 Interfaces and signaling contact of the switches
SCALANCE X-300
92 Operating Instructions, 02/2012, A5E01113043-12
Transmission medium
Data is transmitted over single mode FOC. The wavelength is 1310 nm or 1550 nm.
The core diameter of the single mode FO cable is 9 or 10 µm; the light source is a laser
diode. To transmit a signal, only one mode (light beam) is used greatly reducing dispersion.
As a result, the maximum range of single mode FOC is greater than that of multimode FOC.
Transmission range
The maximum transmission distance (segment length) is 120 km for 1000Base-LX
transmission.
IE Switches X-300 connector technology
SC duplex female connectors are used.
Connector technology of the IE Switch X-300EEC
FC duplex female connectors with the following characteristics are used:
● Maximum range: up to 3 km
● Wavelength: 1310 nm
● Transmission mode: Multimode
● Standard: 100Base-FX
4.3.3 Signaling contact
The signaling contact (relay contact) is a floating switch with which error/fault states can be
signaled by breaking the contact.
Error indication
● The signaling by the signaling contact is synchronized with the fault LED, in other words,
all errors displayed by this LED (freely configurable) are also signaled on the signaling
contact.
● If an internal fault occurs, the fault LED lights up and the signaling contact opens.
● The connection or disconnection of a communication node on an unmonitored port does
not lead to an error message.
● The signaling contact remains activated until the error/fault is eliminated or until the
current status is entered in the fault mask as the new desired status.
