Fluke Networks issues DSX CableAnalyzer adapter for ix Industrial Ethernet connector

Fluke Networks, Hirose and Harting have released an adapter supporting the ix Industrial connector for Fluke’s DSX CableAnalyzer family of network cabling certification tools. The ix Industrial is a rugged Ethernet connector for harsh environments, based on IEC 61076-3-124 standard with a 70% smaller size than the traditional 8-pin modular (“RJ-45”) connector. The new adapter allows the DSX Series to connect to cabling systems employing the ix Industrial connector for the purposes of pre-startup verification and troubleshooting.

101 Series: Set Your Reference Like a Wizard!

When it comes to testing fiber systems, connector loss refers to the loss of a mated pair of connectors – it’s actually impossible to measure a single connector. To test the loss of the first connector, it must be mated to a similar, known quality connector. That’s where Test Reference Cords (TRCs) come in. But you’ve got to take into account the loss of the TRCs by calibrating your tester to 0 dB of loss. This is done by setting a reference, and it is the most important step in Tier 1 fiber testing using an optical loss test set (OLTS). Setting a reference needs to be done whenever the TRC has been removed from the output port on your tester, and whenever the TRC has been cleaned and inspected.

Cabling Mistakes #9: Rely on Duplex Tester for MPO Cable Certification

Let’s take a look at the #9 Dumb Thing that smart people do when testing network cabling systems—relying on a duplex tester for certifying MPO trunks. Field testing is the only way to ensure that MPO links meet the application performance requirements. Despite the fact that pre-terminated MPO fiber cables are manufactured and tested by vendors to comply with ANSI/TIA and international standards, there are many factors that can potentially impact performance. First of all, MPO connectors are harder to clean than duplex connectors. The 12-fiber MPO interface features an array with a much larger surface area, which unfortunately makes it easier to move contaminants from one fiber to another within the same array during the cleaning process. 40 and 100 Gbps MPO fiber applications also have much lower loss budgets so it’s important to ensure the highest testing accuracy as possible.
