  1. Fiber Optic Infrastructure Could Unlock 5G’s Potential

    5G, the fifth generation of wireless cellular communications, is a mixed bag to say the least. Originally it was marketed as a host of services and new capabilities that would skyrocket humanity to the future. Well, time has certainly passed, and most users, even in modern cities, are still not experiencing faster mobile data rates, let alone the future technoscape humanity is supposed to be living in. Though a global pandemic has certainly slowed the expansion of 5G technologies, it is likely that much of the hype around 5G was just that − hype.

    New Infrastructure Needed

    Possibly one of the biggest constraints to 5G, or really the future of the wireless revolution and the explosion of the Internet of Things, has been the infrastructure for wireless network base stations. Though the hype implies otherwise, t

  2. Simplifying the Many Differences among Ethernet Cables

    If you Google “Ethernet cables” you’ll get about 5 million hits. It’s no wonder that shopping for Ethernet cables can be confusing. But if you simplify the cables down to their main differences, it’s much easier to choose the one that’s best for your use.

    This blog post explains the chief differences among the cable categories. But instead of trying to cover everything from Cat1 to Cat8, we discuss only the four categories used most in office networks, data centers and residences: Cat5e, Cat6, Cat6a and Cat7. We conclude by clarifying some of the choices you might also have to make about cable jacketing t

  3. Why Custom?

    Custom Coax Assmbly

    The word “custom” sounds expensive. Often it is. A new Porsche 911 S Exclusive is not cheap, but if you want one with a custom “python green” paint job, it’s an extra $98,000. Examples like that might make one wary about going the custom route.

    One reason more people don’t buy custom cable assemblies is that they think they can’t afford it. While it’s true that nonstandard assemblies can be pricier up front, they can save you money in the long run. This blog post points out three ways you can come out ahead with custom cables.

    Longer Lasting

    Going custom means choosing a cable and connectors that were specifically designed for a certain purpose. When your installation operates within the electrical parameters, tolerances and environment

  4. Getting On and Off the Fiber Optic Superhighway with Transceivers

    fiber transceiver

    It’s no mystery why fiber optic technology has grown in popularity since it was introduced in the 1970s. Sending data via infrared light pulses on a fiber line, rather than electrically over copper cable, allows the transmitting of more information faster, over longer distances and with no threat of electromagnetic interference. That’s why it is often the choice for systems that demand high bandwidth over long distances, as well as short distances with large bandwidth requirements such as data centers.

    But not everybody understands the crucial step onto and off of the fiber optic superhighway – the fiber optic transceiver.

    A fiber optic (or optical) transceiver serves as both

  5. Time to Get Organized with Cable Management

    Neat Patch

    We’ve all seen the equipment rack or IT closet that lacks cable management. Confusion reigns, as masses of wires run in all directions and every patch bay looks like a rat’s nest. You feel sorry for whoever must go in and install or re-route cables or troubleshoot wiring problems.

    The good news is that wire routing is a universal challenge, so there are products to tame the cable confusion. In fact, there are hundreds of cable management items to choose from, so let’s simplify things. Most of them can be divided into three groups: rack and cabinet attachments, cable routers along walls and ceilings, and ties and straps for bundling.
