Because present-day enterprise data networks increasingly rely on fiber optic cabling, it is more important than ever for installers and network owners to use Optical Loss Test Sets (OLTS) certify and document that their fiber links meet established industry standards to protect against network downtime and lost revenue.
The Fluke Networks DTX-CLT CertiFiber® OLTS enables you to easily and accurately certify two fibers concurrently over two wavelengths according to custom requirements or established industry specifications. Quickly and efficiently conduct troubleshooting with a convenient integrated Visual Fault Locator (VFL).
The DTX-CLT CertiFiber OLTS does not certify copper cable.
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 adapters 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.
Save time managing results with LinkWare Cable Test Management Software
LinkWare is also available free from our web site. Once your work is done, you can give this powerful application to your customers so they can have instant access to the data electronically. You can also print test results or you can export the data as an Adobe Portable Document Format (PDF).
Extensive data management capabilities with LinkWare:
LinkWare Software prints professional, graphical reports with color graphs depicting the measured test parameters. You can choose which parameters to print and the order in which graphs appear. Reports can also be customized with your company logo.
New LinkWare Stats option provides a graphical analysis of your entire cable plant
LinkWare now supports LinkWare Stats, a new automated statistical report option that allows you to move above and beyond the page-per-link report and see your entire cabling infrastructure. It analyzes and transforms LinkWare test results data into charts and diagrams that reveal your cabling plant performance; this report summarizes your entire cabling infrastructure in a compact, graphical format that makes it easy to verify margins and to spot anomalies.
