REQUIRED ACCESSORIES
(2-3) one-meter patch cables – ensure proper connector type and fiber type
(1) fiber optic mandrel – used for setting references with multimode cables only; see table below for mandrel sizes
multimode reference cables must be wrapped and secured around a mandrel as required by national and
international Fiber Optic Test Procedures (FOTPs). See Figure 1 above for a diagram of a mandrel wrap.
if you are testing at both 850nm and 1300nm, each light source wavelength will require its own mandrel-
wrapped patch cable.
EQUIPMENT PORTS
Figure 2 shows the ports used during this procedure. These ports may vary depending upon the model of equipment.
