Introduction to Programming 1
Laser Selection Numbers
The laser selection number, [l], identifies the upper or lower wavelength
laser source for dual wavelength Laser Source modules and Return Loss
modules with two internal laser sources. The lower wavelength source is
denoted by 1. The upper wavelength source is denoted by 2.
NOTE
If you do not specify a slot or channel number, the lowest possible number is
used as the default value. This means:
• Slot 1 for the 8163A/B and 8166A/B mainframes.
• Slot 0 for the 8164A/B mainframe.
• Channel 1 for all channels.
NOTE
For Return Loss modules, 0 denotes the use of an external laser source as the
input to your Return Loss module for the following commands:
