
The power measurement in watts (W, mW, µW) or
decibels (dBm). To change the unit, see "To change the
unit for power measurements" on page 12.

The numbers for the channels flash in sequence when
the meter measures power.

These sections switch between the wavelength that
the meter measures (nm shows) and the record
number for the next record you save (RECORD shows).

Power Measurements on 8- and 10-Fiber
Cables
The meter lets you measure power on MTP/MPO cables
made for 40G and 100G standards:

On 40G cables, the four middle fibers are dark. On 100G
cables, one fiber on each side of the connector is dark.

The meter shows -99 dB and no ovals for the dark fibers.

When the meter sees the 40G or 100G configuration, it
saves power measurements for only the 8 or 10 other
fibers.
