Fiber-Optic Connection

Overview

2.9.1
With the integrated Fiber-Optic Modules (FOM), it is possible to connect an SWT 3000 to the PowerLink PLC
system or a multiplexer via fiber-optic cables. The communication of 2 SWT 3000 units via fiber-optic cables is
also possible. A distance of up to 150 km can be covered.
2 fiber-optic modules (FOM-1 and FOM-2) for the main and alternate path can be integrated into the SWT
3000 system.
Alternatively, the Copper Line Equipment (CLE) module for the wired analog transmission can be inserted at
slot FOM-1.
With the fiber-optic modules, the following cases of operation can be carried out:
•

Connection to the PowerLink PLC system

•
Connection to a multiplexer
•
Direct connection via fiber-optic

Figure 2-12
The SWT 3000 is connected via fiber-optic cables (for each transmission direction one fiber) to the PowerLink.
The functional performance of the SWT 3000 is like an integrated SWT 3000 (iSWT). That is, all possible
variants with iSWT can be carried out with the stand-alone SWT 3000 via fiber-optic cables. The programming
of the SWT 3000 in this case is only possible via PowerLink and the service program PowerSys. In the
PowerLink system, 2 SWT 3000 can be connected via fiber-optic cables (iSWT-1 and iSWT-2). The fiber-optic
modules in Power Link are installed in the slots of the PU4.
NOTE

In order to integrate an SWT 3000 with PU4 into the PowerLink system, a PowerLink with CSPi (release
3.5.xxx) is necessary.
The main transmission path of the integrated SWT 3000 is the PLC connection of the PowerLink via high-
voltage line.
You can connect a digital alternative path of the SWT 3000 as follows:
•
Direct electrical connection to the remote SWT 3000 device
•
Optical connection via a second FOM
