Certifying Fiber Optic Cabling
Overview of Features
The optional DTX-MFM and DTX-SFM fiber modules are
used with a DTX Series CableAnalyzer to test and certify
fiber optic cabling installations. The fiber modules offer
the following functions and features:
• Measures optical power loss and length on dual-
fiber cabling. The DTX-MFM tests multimode cabling
at 850 nm and 1300 nm. The DTX-SFM tests
singlemode cabling at 1310 nm and 1550 nm.
• Each module transmits both wavelengths (850 nm
and 1300 nm; 1310 nm and 1550 nm).
• Provides pass/fail results based on industry-standard
limits.
• Visual fault locator helps you locate breaks, bad
splices, bends, and check fiber continuity and
polarity.
• FindFiber
function helps you identify and verify
fiber connections.

To avoid possible eye damage caused by
hazardous radiation:
• Never look directly into optical connectors.
