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.
