Simplifying Data Center Network Design with Universal POLARITY Fiber Cassettes

Polarity means that a fiber optic link’s transmit signal at one end of the cable must match the corresponding receiver at the other end. While this concept might seem simple, it becomes more complex with multifiber cables and MPO connectors. Leviton’s new Universal Polarity Fiber Cassettes that help data center managers simplify things even further. The Base12 cassettes allow for the same interchangeable cassette on both ends of a Method B trunk in a fiber channel, reducing the complexity of a fiber network, ensuring consistent polarity, and streamlining network deployment.

Polarity is a critical part of any fiber network. Polarity means that a fiber optic link’s transmit signal at one end of the cable must match the corresponding receiver at the other end.

Sometimes a Change Just Makes Sense

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.

Senko intros LC EZ-Flip polarity reversible fiber-optic connector

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 enables tool-less polarity change

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.

Getting polarity Right

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.
