After its introduction to the market in 2009, bend insensitive multimode fiber (BIMMF) received plenty of attention. But some might not realize that bend insensitive singlemode fiber (BI-SMF) actually came first.

Due to smaller cabinets and longer wavelengths used in outside plant (OSP) and passive optical network (PON) applications, BI-SMF was introduced in 2007 under the International Telecommunications Union (ITU) G.657 standard.

However, splicing ITU G.652D standard singlemode fiber to newer G.657 BI-SMF fiber can cause some confusion.

There’s no escaping the push to secure industrial applications. The end of support for Microsoft’s Windows XP operating system is just the latest situation that contributes to the need to make sure that industrial networks have cyber security measures in place.

The challenge is how to go about it. If you’re the person tasked with security—and if you're reading this, you probably are—the ambiguity surrounding security for industrial systems has probably struck you already.

One tool in the toolbox to help you improve the cyber resilience of your facility is to leverage the know-how of your company’s IT security experts. Before you start running for the hills at this suggestion, I hope you will read on and find out how this may actually help.

Ask yourself, “Is what I’m trying to do reasonable?” A lot of times, even a well-oiled high-performance wireless router just isn’t going to be able to do what you want, but it can be hard to know where the line is drawn. For instance, if you are trying to stream uncompressed, high definition (1080p) video to a large-screen TV, it can require a sustained bitrate of 25-50Mbps (Bluray/H.264/MPEG-4). Most routers claim at least 300Mbps speeds on the packaging, so that should be no problem, right? It turns out, though, that once error correction and normal household interference are factored in, the effective speed of that router paired with your set-top streamer or laptop is closer to a maximum of 30Mbps, and a steady-state of 15-20Mbps. This happens to be in the sweet spot for video with more compression, like DVD/H.262/MPEG-2. Lower quality video will look just fine on smaller screens, but softer-edged and less vivid on big displays. This is how YouTube and Netflix manage to run a perfectly acceptable video on your tablet with streaming rates around 1Mbps or less – on a tiny handheld screen you won’t notice that 98% of the information has been thrown away. On a 60” LED-backlit flat panel with surround sound it looks noticeably blocky and sounds crunchy. Advertising promises are mostly to blame for this mismatch of expectations, not the performance of your network. If you are doing something that needs high sustained rates, wire it.

Believe it or not, virtualization has been around for longer than one might think.

In the early 1970s, IBM offered the first commercial main frame to support virtualization. In 1997, Apple used virtualization technology to run a copy of Windows on a Mac to get around some of the incompatibilities.

But mainstream adoption of server virtualization in the data center didn’t really take off until the late 1990s when VMWare began offering products, followed quickly by several other vendors.

Several months ago we asked whether you have moved wireless projects off the back burner yet. The reason we asked is because new advances in technology and standards mean it’s probably time to take a fresh look at industrial wireless.

One of the most common concerns about wireless for wide-ranging mission critical applications has always been – and still is – reliability. Now, in part to the use of an updated and improved protocol called Parallel Redundancy Protocol (PRP) wireless applications are very reliable.

In this Part 1 of a two-part series I explain why PRP technology makes wireless worth another look.

Do you think that Category 8 will be specified in standards for offices and commercial buildings in future?


Category 8 cabling is under development to support the next generation 40GBASE-T Standard over balanced copper cabling for distances up to 30 meters. It is primarily intended for switch-to-server connections in a data center. In the IEEE 802.3 Call for Interest on Next Generation BASE-T a chart was presented that forecasted the demand for higher speed switch-to-server connections as shown below. The demand for 40G (blue) will start to pick up in the 2015 to 2018 time frame.
