5 Setting Up Your RTU
Detecting the Fibers Connected to the Optical
Ports
You must perform the detection of the optical ports in the following cases:

when you install a new RTU.

when you connect optical fiber to previously unused ports to activate
testing (see Cleaning and Connecting Optical Fibers on page 77).
The RTU must first detect the fibers connected to the ports. It will
automatically create the optical routes, test setups and test programs (for
more information, see Managing Optical Routes on page 139).
Once the detection is completed, you can configure a remote switch
(ROTAU) if you want. The RTU will only take into account (detect) ports to
which fibers of at least 50 meters are connected.
To detect new ports:
1. From the main menu, select Configuration > Remote Test Unit.
2. Under OTAU, click Detect.
