PART 1 - VERIFY PROPER OPERATION OF THE EQUIPMENT, cont.
Testing at 1310nm ONLY – skip to
PART 3a
Testing at 1310 and 1550nm – continue with
PART 2b
The ZOOM 2 should show approximately -10.00 dBm. If the reading is below -12.00 dBm, the patch cable should be
replaced.
Once proper operation has been verified, remove the first patch cable from both units and set it aside.
Connect the power meter and light source together with the second patch cable as shown in Figure 2.
The ZOOM 2 should show approximately -10.00 dBm. If the reading is below -12.00 dBm, the patch cable should be
replaced.
Once proper operation has been verified, remove the second patch cable from both units and set it aside.
Connect the power meter and light source together with the third patch cable as shown in Figure 2.
The ZOOM 2 should show approximately -10.00 dBm. If the reading is below -12.00 dBm, the patch cable should be
replaced.
Once proper operation has been verified, continue on to the next step.
PART 2a - SET REFERENCE (1310nm)
Setting a reference is commonly referred to as “zeroing”.
With the power meter and light source still connected as shown in Figure 2, press and hold
button on the ZOOM 2 to
set the reference for 1310nm.
The ZOOM 2 display should change to show readings in ‘dB’, and the power reading should be
approximately 0.00 dB. This means that the meter and light source have been successfully “zeroed” at
1310nm.
