As enterprise bandwidth demand increases, it is more important than ever for installers and network owners to certify and document that their fiber links meet established industry standards, to protect against network downtime and lost revenue.

The Fluke Networks DTX-EFM2 Encircled Flux Multimode Modules for the DTX CableAnalyzer enable you to easily and accurately test while ensuring compliance. EF requirements are defined in the TIA-526-14-B and IEC 61280-1-4 standards. Encircled Flux compliance reduces loss measurement variation to a goal of +/- 10%, decreasing measurement uncertainty and improving measurement repeatability every time. This is the standard that cable manufacturers will expect for warranties.

The DTX Encircled Flux Fiber Modules matched with EF test reference cords (DTX-EFM2) are a quick and easy way to upgrade to EF compliance. No special training or change to normal testing procedures is required.



Encircled Flux Compliant Multimode Fiber Certification

TIA-526-14-B and IEC 61280-1-4 now require tighter launch conditions to reduce measurement uncertainty. With the DTX-EFM2, users who are familiar with the DTX CableAnalyzer can easily make use of these new modules to perform EF compliant testing with no additional training. The DTX-EFM2 with the Encircled Flux Test Reference Cords (EF-TRCs) provide the most efficient and practical EF standard compliant testing solution. These EF-TRCs are individually tuned so that any DTX-EFM2 produces an EF compliant launch at the end of the EF-TRC.

Basic (Tier1) fiber certification

DTX Fiber Modules provide a Basic (Tier 1) fiber certification solution – loss, length and polarity. Validate fiber link performance per industry standards. Measure optical loss at multiple wavelengths, measure fiber length and verify polarity. You can test two fibers in both directions at both wavelengths with incredible speed without swapping main and remote units, a capability only available from Fluke Networks. Interchangeable connector adapters allow reference and test connections that meet TIA/ISO standards for most SFF (small form factor) fiber connectors.

Unlike competitive fiber testers which measure length and two loss measurements per Autotest, DTX is the only fiber test solution that measures length and four loss measurements per Autotest – all in about 12 seconds. With DTX Fiber Modules, you can speed through fiber testing five times faster than the competition.
