Chapter 8: Certifying Fiber Optic Cabling
Note
The fiber modules are not compatible with the
DTX-ELT.
Overview of Features
The optional DTX-MFM2, DTX-GFM2, and DTX-SFM2 fiber
modules are used with a DTX-1800, DTX-1200 or DTX-LT
CableAnalyzer to test and certify fiber optic cabling
installations. The fiber modules are standard with the
DTX-CLT CertiFiber. The modules offer the following
functions and features:
• Measures optical power loss and length on dual-fiber
cabling. The DTX-MFM2 tests multimode cabling at
850 nm and 1300 nm. The DTX-SFM2 tests singlemode
cabling at 1310 nm and 1550 nm. The DTX-GFM2
features a VCSEL for testing multimode cabling at
850 nm and 1310 nm when a VCSEL source is required.
• Each module transmits both wavelengths (850 nm and
1300 nm, 850 nm and 1310 nm, or 1310 nm and
1550 nm).
• Interchangeable connector adapters allow reference
and test connections that meet ISO standards for most
SFF (small form factor) fiber connectors.
• 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.
