Monitoring Optical Power
The power meter lets you monitor the optical power
produced by a source such as an optical network
interface card or optical test equipment.
The tester offers two versions of the power meter
function:
• SINGLE TEST mode: Measures power in the current
remote end configuration (Smart Remote, Loopback,
or Far End Source mode). Takes one power
measurement at 850 nm and 1300 nm (DTX-MFM2),
850 nm and 1310 nm (DTX-GFM2), or 1310 nm and
1550 nm (DTX-SFM2). You can save the power
measurement in this mode.
• MONITOR mode: Monitors power continuously at
the input port at 850 nm, 1300 nm, 1310 nm, or
1550 nm. This measurement cannot be saved.
Figure 18 shows the equipment required for monitoring
power in the MONITOR mode.
