7.3 Performing a Multicore Loss Test
Connect one end of the communication fiber that you specified to the master’s light source port (optical
port 2), and connect the other end to the slave’s optical power measurement port (optical port 1). Then
perform the multicore loss test.
Procedure
After the settings in sections 7.1 to 7.2 have been completed, open the loss test screen, and perform
the multicore loss test procedure.
Executing a Multicore Loss Test
WARNING
• While this instrument is producing light, do not remove the optical fiber cable, because light
is emitted from the light source port. Visual impairment may occur if the light enters the
eye.
• Close the covers of any light source ports that do not have optical fiber cables connected
to them. On models with two or more light source ports, visual impairment may occur if light
that is mistakenly emitted from the wrong port enters the eye.
3.
Press the
Loss Test START
soft key.
The optical signal used to transmit the core
number is sent to the slave.
On the menu, “Loss Test START” changes to
“Loss Test STOP.”
After loss testing stops, “Loss Test STOP”
changes back to “Loss Test START.”
5.
Press the
Loss Test START
soft key.
The light turns on.
On the menu, “Loss Test START” changes to
“Loss Test STOP.”
After loss testing stops, “Loss Test STOP”
changes back to “Loss Test START.”
Optical Power Adjustment
Adjust as necessary (see section 7.4).
1.
Connect the optical fiber under loss test to the optical
power measurement port.
2.
Use the
rotary knob
and the
arrow keys
to select the
core number of the connected fiber.
4.
Connect to the light source port the optical fiber that
corresponds to the core number transmitted from the
master.
It may take time to receive the core number from the master.
Slave
Master
Specify skipping as necessary.
When the core number is received, the Loss Test
START soft key is enabled.
Follow steps 1 to 5 to perform a multicore loss test.
Check marks appear over core numbers whose loss tests have been completed.
