In a recent Cable Testing 101 series blog on mixing multimode fiber types, we covered the considerations surrounding mixing legacy 62.5 micron (µm) OM1 fiber with today's laser optimized 50µm OM3 and OM4 fiber and highlighted the "gainers" that can happen when transmitting from a smaller 50µm fiber core to a larger 62.5µm fiber core.

This question often gets asked in my classes at the same time as when talking about launch methods using launch and tail fibers. So let’s talk about launch fiber compensation.

Last month we posted a blog about HDBaseT that explained the application and how testing isn't really any different since standards-based Category 5e, 5 or 6A will support it. But maybe you've also heard about power over HDBaseT, or POH, and you're wondering how that differs from power over Ethernet (PoE).

Alien crosstalk is a relatively new measurement that’s widely misunderstood. I’m often asked why it’s an important measurement and if it’s required to be measured by the standards. Also misunderstood is the sampling criteria for alien crosstalk measurements, which are applied so that not all links have to be tested?

OM3 and OM4 multimode fiber are two common types of fiber used in local area networks--typically in backbone cabling between telecommunications rooms and in the data center between main networking and storage area network (SAN) switches.

While probably one the least talked about standards, and one that is often considered voluntary, the TIA-606-B labeling standard exists for a reason.
An unlabeled infrastructure results in an unmanageable mess that ultimately makes every reconfiguration and troubleshooting task a time-consuming, frustrating and costly tracing game of hunt and peck.

Maximizing productivity in today's fast-paced workplace is essential. Whether installing new fiber links or troubleshooting an existing network, the faster you can locate a problem, the faster you can fix it. That's easier said than done when you are faced with a complex network of fibers, connectors and patch cords.
