Measuring Core Power with OFI 400 Model
The following procedure may be used for measuring fiber core power.
1 Turn on the OFI 400 by pressing the [Power] key.
2 Gently insert the fiber to be tested into the fiber groove at the top of the OFI 400 head (refer
to Figure 2-3).
3 Pull down and hold the trigger to depress the fiber against the optical assembly.
4 Observe the OFI 400 display readings.
The core power measurement will be displayed in [dBm].
Note:
The OFI 400 model is calibrated for Corning 250
m
m SMF-28 fiber at 1550 nm for
core power measurements. Readings will be invalid for fibers other than 250
m
m bare fiber
(approximately 20 to 30 dB below the core power of 3 mm SMF jumper cable).
