8.3 Setting the Optical Output Power of the DFB Module
8.3.1 Specifying the Optical Output Power of the Module
Subject You can set the optical output power in two different ways:
• From the OSICS Mainframe Main Setup menu, you can simultaneously set the
optical power of all modules to the same value: see section Setting the Optical Output
Power of All Installed Modules, p. 38 .
• From the DFB Unit Setup menu, you can set the output power of the module
individually as explained in the following procedure.
The power value is software-limited to stay within the specified range.
Before Starting • Set the optical power unit from the OSICS Mainframe Main Setup menu (see section
Selecting the Power Unit for All Installed Modules, p. 38 ). You cannot set the power
unit of an individual module.
Procedure 1. Access the DFB Unit Setup menu (see section Accessing an OSICS Module Setup
Menu, p. 33 ).
2. Turn the rotary knob to put the cursor before the Set Power menu and press the
knob.
The
Set Power menu appears and displays the current power setting.
