Exploring Dual-Power Feeds in Data Centers

Things like always-on technology, streaming content and cloud adoption are creating high demand for efficient, resilient and fast data centers that never let us down.

To meet these needs, dual-power feeds – two independent electrical feeds coming into a data center from the utility company – are becoming more common to reduce the chance of a complete outage (or not having enough power). This type of power set-up is often seen in Tier 4 data centers. If one of the two power sources suffers from an interruption, the other source will still supply power.

In a recent article from Belden, Dennis Blouin discusses methods to deploy dual power feed methods.

Recognizing Multimode Fiber Types By Color

In a recent blog from Adrian Young from Leviton discusses how to recognize multmode fiber types by color.  Color-coding is a big help when identifying individual fibers, cable, and connectors. For example, cable jacket color typically defines the fiber type, and can differ based on mode and performance level. These colors are typically chosen by industry standards bodies. However, there are some non-standardized colors and inconsistencies that you should be aware of. Read more…

Centralized vs. Decentralized UPS Systems

One of the first steps in choosing the most appropriate UPS solution is deciding whether to use a centralized or decentralized setup. While both have their advantages, knowing how to answer this question depends on a number of factors. In a recent … [Continue reading]

4 Basic How-To Rules of Fiber Polarity

Understanding fiber polarity and how to connect a system with absolute certainty is key to a successful installation. The tricky part, however, is that there is no “right” way to approach fiber polarity. Each manufacturer usually provides its own … [Continue reading]

Why can’t I use the 2-Cord Test Method?

2-Cord vs 1-Cord Method Like the TIA and ISO Standards, Fluke Networks promotes the use of the 1-cord method to set reference for fiber loss measurements.  Why is this method preferred? Because the 1-cord method provides the lowest uncertainty … [Continue reading]
