This quick reference guide demonstrates the procedure for performing a dual-wavelength insertion loss test at both
850nm
and
1300nm
.
to test at only one wavelength, ignore the steps related to the other wavelength
There are three main parts to performing an insertion loss test:
PART 1
verify proper operation of the test equipment and patch cables;
PART 2
set a reference for the wavelength(s) used during fiber link measurement; and
PART 3
take measurements.
EQUIPMENT PORTS
Figure 2 shows the ports used during this procedure. These ports may vary depending upon the model of equipment.
REQUIRED ACCESSORIES
ensure test cables have the proper core size and connector type
multimode reference cables must be wrapped and
secured around a mandrel as required by national and
international Fiber Optic Test Procedures (Figure 2)
a mandrel-wrapped reference cable is required for each light source wavelength being used for testing
