The optional DTX Compact OTDR
™
Optical Time Domain
Reflectometry modules are used with a DTX Series
CableAnalyzer to locate and characterize reflective and loss
events in optical fibers. The modules offer the following
features:
• Automated OTDR trace and event analysis help you
locate and analyze reflective and loss events on
multimode (850 nm and 1300 nm; 50 µm and 62.5 µm)
and singlemode (1310 nm and 1550 nm; 9 µm) fiber.
• Displays OTDR results in summary format, as a table of
events, or as an OTDR trace. PASS/FAIL results are based
on factory-installed limits or limits you specify.
• Visual fault locator helps you locate breaks, bad splices,
bends, and check fiber continuity and polarity. See
Chapter 9.
