Certifying Fiber Optic Cabling
Overview of Features
The optional DTX-MFM2, DTX-GFM2, and DTX-SFM2 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-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 for Gigabit Ethernet applications.
•
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.
