Is something...APC Polishing Advice to Improve Apex Offset and Angle Measurements
Of the two common ferrule shapes involved in APC polishing – conical and step – the step ferrule is by far the easiest in terms of controlling geometries. Step ferrules are more expensive than conical ferrules. However, from a purely...Using Chemical Mechanical Planarization (CMP) to polish MT ferrules and get repeatable, predictable results
I’ve been watching the development of Chemical Mechanical Planarization (CMP) since the 1980s, when this polishing process was first used in the semiconductor industry. Of course, my interest in CMP became more personal when this process was introduced to the...Patch cord gain: Shedding light on this perplexing issue
Here is a question several customers have asked me. Have you experienced this issue? “When measured on my properly calibrated IL/RL meter, some of my patch cords show ‘gain.’ How can this be possible? Since a patch cord cannot have...Trade show best practices, improved processes and a little pixie dust.
The best laid plans of the FOC February Marketing Blog fell to a delay by irony. This month’s topic of trade shows is posting in March due to the logistics of our shows usurping much of the past month. One...Looking at our industry from a systems perspective: The future of cable is inextricably tied to connectivity.
For years, connectivity in the cable industry was considered a “throw it over the wall” issue with a focus on leaving the problem to others who then became responsible for the convenience of connecting the cables designed to the outside...Looking at key benefits of the FastMT fiberscope and a discussion on automated vs. manual optical inspection
In your fiber optic cable assembly facility, when an operator visually inspects one of your connectors – and sees a defect on a fiber – will the operator define it as a defect or call it a scratch? It’s a...Cablers: Advice to efficiently reconfigure fiber optic process lines for add-on products – without resulting in suboptimized products
When I was a process engineer at a large cabler, we could reconfigure our fiber optic process lines in about 20 minutes. In a 3-shift day, we could produce 8 different products. Unfortunately, most cablers don’t enjoy this level of...Cablers: Are you looking to work with specialty cables or furcation tubes? If so, here are key points to consider.
A growing trend in the fiber optic industry is the increasing use of specialty fibers. Clearly, telecommunications and data communications applications are the high-volume users of fiber optics, yet other areas are burgeoning. In fact, many specialty fiber optic...Helpful Epoxy Tips (and a Few Tricks)
In the fiber optic cable assembly process, working with epoxy generates a lot of questions. When I visit fabrication facilities, we discuss the finer points of mixing the material, loading syringes, minimizing waste, heat-treating crystallized epoxy, and more. For...Advice for raw material suppliers planning to sell to the optical cable industry: 4 points to consider – and pitfalls to avoid
In the “dog-eat-dog” world of raw materials, competition is stiff. Margins are tight. Opportunities are rare. Is your company eying fiber optics as a new market?
