Fiber Testing Overview
4−2
This chapter describes how to certify optical fiber cabling. The
procedures in the chapter are sufficient for most fiber certification jobs.
If the requirements of the job are not addressed here, refer to Chapter 7,
Expert Mode for Fiber Testing.
Three connection configurations are available for optical fiber
certification testing.
Double-Ended, Single Fiber
Double-ended single fiber configuration tests one fiber, using two Fiber
SmartProbes. For single fiber testing the fiber must go from the
transmitter/laser source on the DualRemote to the detector on the
WireScope. When the 850nm multimode probe is in the DualRemote, the
units can be as much as 4 km apart. When the 1300nm multimode probe
is in the DualRemote, the units can be as much as 10 km apart. When
singlemode probes are used, the WireScope and DualRemote can be as
much as 50 km apart. All maximum lengths are barring excessive loss.
Double-Ended, Fiber Pair
Double-ended fiber pair configuration tests two fibers, using two Fiber
SmartProbes. When multimode probes are used, the WireScope and
DualRemote can be as much as 4 km apart. When singlemode probes are
used, the WireScope and DualRemote can be as much as 50 km apart. All
maximum lengths are barring excessive loss.
