Network and data center managers have their own favorite brands when it comes to connectivity, cabinets, PDUs and cable management. But every now and then, a brand fails to deliver. That’s exactly what happened at Humana, the 3rd largest health insurance company in the nation. Despite their brand loyalty on fiber connectivity, the jumpers they were using just didn’t cut it when it came to port access in high-density patching areas or needing to change polarity on the fly.
MPO technology and components are widely use in 40/100G network. However, to maintain the correct polarity in MPO systems is not always easy. Fortunately, there are approaches that can facilitate correct MTP/MPO polarity maintenance in serial duplex signals connections and parallel signals connections.
Senko’s new LC EZ-Flip fiber-optic connector is designed for applications where easy changes in polarity of LC duplex fiber connectors may be required. Technicians can change the polarity of the LC EZ-Flip within 3 seconds following three steps that can be performed without tools. The fiber connector is based on the uniboot LC and can be used in high-density applications thank to the incorporation of a Push/Pull Tab. A visual indicator built into the connector housing eases visual inspection of the polarity.
Panduit’s Uniboot Push-Pull Fiber Patch Cord supports tool-less, in-the-field polarity change and provides remarkable insertion loss performance, easy field moves/adds/changes, and a low profile to reduce cable-volume density. The cord’s compact dimensions can save up to 40% of termination space compared to conventional connectors. The patch cords are available in singlemode and multimode versions.
Understanding complex cable connectivity is crucial to the overall installation and your project’s success. The top five connectivity issues that impact performance are: Use of the incorrect network interface type; selection of proper cable type; reversed polarity; mismatched connectors; and poor installation practices.
Polarity needs to be determined during the design phase so that the right components can be purchased. Unfortunately, the confusion surrounding polarity often means finding out that you’ve ordered cables or patch cords with the wrong polarity. And since pre-terminated MPO assemblies and jumpers are typically made to order (and often nonreturnable), ordering the wrong polarity risks unexpected project delays and expense. Thankfully, the combination of being able to test for polarity and new MPO connectors that allow you to change polarity in the field is putting an end to the risk. This article takes a closer look.

Polarity defines direction of flow, such as the direction of a magnetic field or an electrical current. In fiber optics, it defines the direction that light signals travels through an optical fiber. […]
Roundabouts – or traffic circles – have been around since the early 1900s. Yet, it seems some people still have trouble navigating them. The whole purpose is to keep traffic moving without […]
