  2. Copper Clad Aluminum vs. Pure Copper Cables

    When shopping for Cat5e or Cat6 network cables, make sure you are comparing apples to apples. One of the most common tactics of the “low cost leaders” is to use aluminum instead of copper wire. This can lead to network issues from using inferior materials to transmit the signal. The problem is further heightened because there are no visual differences between a CCA cable and a pure copper cable. ShowMeCables guarantees that all of our patch cables are pure copper and are ready for Cat5e, Cat6, Cat6a or Cat7 networks.

    Creating a Copper Clad Aluminum Cable

    Looking to cut costs, manufacturers started using aluminum wire dipped in a thin coating of copper. This technique created an aluminum core cable surrounded by a thin layer of copper. If you have ever purchased coax cable,

  3. Better Know a Connector: SMA

    The SMA connector(SubMiniature version A) is a 50 ohm coaxial connector. It is visually similar to an F type connector that is commonly used for audio/video communication, but has different dimensions, mechanical properties and is used for different applications such as RF communications up to 18 GHz. Due to its construction, SMA connectors provide a strong and durable connection that minimizes reflections, limiting attenuation, and makes it a great choice when working with microwave frequencies.

    SMA Male Connector

    The SMA male connector is identified by inside 1/4″-36 threads and a 5/16″ hex nut. A standard polarity connector will have a male pin.

  4. How To: Make a Dread Hanger Cable Manager

    If you’ve spent any time on the Internet in the last year, chances are you seen some great examples for how to organize long cables. Today, the ShowMeCables blog is bringing you a DIY for creating a similar effect in your own storage closet.

    Step 1. Choose Your Model

    This is, arguably, the hardest step of the process as there are many different routes to take. Just the word “dreadlocks” conjures up images of the well-loved Rastafarian Bob Marley, the godfather of dreads himself. Wiz Khalifa, the lead singers of Korn and Whoopie Goldberg also sport the famous hairstyle with 

    effortlessness. For the adventurers out there, Capta

  5. Discussing Cat5 Length Limits

    Cat5 cable is a standard term for twisted pair cable commonly used for connecting PCs and hardware to different equipment. It has been replaced by Cat5e, which is an enhanced version of Cat5. These share many of the same physical characteristics including distance limitations, but Cat5e is designed for faster networking speeds and reduced crosstalk interference. The maximum length you can run Cat5, Cat5e, Cat6 and Cat6a cable is 100 meters or 328 feet. If you require a longer run, you will need to put an active component, such as a router, in-between the signals.

    The length limit for Cat5 also includes any patch cables, jacks or couplers that are connected in

  6. RJ45 Pinout

    A RJ45 connector is a modular 8 position, 8 pin connector used for terminating Cat5e or Cat6 twisted pair cable. A pinout is a specific arrangement of wires that dictate how the connector is terminated. There are multiple pinouts for RJ45 connectors including straight through (T568A or T568B), crossover, rolled, T1, and loopback. Straight through is the most common type of cable and is used for connecting your computer to your network. The other pinouts are for specialty cables that are used for unique network applications. Straight-Through Pinout Within the family of straight-through color codes, there are two standards recognized by ANSI, TIA and EIA. The first is the T568A wiring standard and the second is T568B. T568B has surpassed 568A and is seen as the default wiring scheme for twisted pair structured cabling. If you are unsure of which to use, choose 568B.

  7. DIY: Create A Shoebox Cable Organizer

    With each purchase of a new gadget comes a plethora of charging cables. It’s easy to absent-mindedly throw everything into a drawer to be sorted or used later. But that method inevitably results in a tangled mess of cables and cords that rivals that of Clark Griswold’s Christmas lights. Here’s a better way to stow away those extra cords so that the next time you need them, you won’t have to battle The Cable-Spaghetti Monster.

    What You’ll Need:

    • Shoebox
    • Scissors
    • Tape (ours is fancy gold duct tape)
    • A pen/permanent marker
    • Cardboard roll (from TP, gift wrap, etc.)
    • Cables!

  8. What is USB Type-C?

    Apple recently unveiled its newest MacBook Pro, announcing that it would use a single USB Type-C port for power and data transfer. USB Type-C has since been the topic of conversation in the tech world, paving the way for exciting possibilities for improved USB standards and devices.

    What is USB Type-C?

    Type-C is a new shape of USB connector which is double-sided with 24-pins. It is reversible, a huge improvement to any of us who have once fumbled with plugging a Type-A connector into a port. While Type-C itself is only a change in shape, the excitement lies in the potential for improved standards. The underlying technology of Type-C could be anything from the outdated USB 2.0 to the latest and greatest USB 3.1 and USB Power

  9. Better Know a Connector: RP-TNC

    TNC connectors (Threaded Neill Concelman) are a 50 ohm coaxial connector. It is a higher performing, threaded version of the more common, BNC connector. It is used for RF communications up to 11 GHz. Due to its construction, with threaded coupling which create a secure connection, it is a great choice when working with microwave frequencies. The TNC connector is available in two varieties – standard polarity and reverse polarity (RP-TNC).

    History of RP-TNC Connectors

    Reverse polarity TNC connectors were popularized by WiFi manufacturers. They were looking for a way to comply with governmental regulations set forth by the FCC to limit consumers from connecting their own antennas. This regulation has largely been abandoned as the connectors are readily available to the general public.

  10. Neat Patch NP2 Smart Cable Management

    The Neat Patch is a new tool for horizontal cable management. It’s innovative approach will save you time and money and will make your installations look professional with very little effort. Most horizontal cable managers amount to little more than cable duct. They allow you to run cables along the front or rear of your rack but fail to take advantage of the interior rack space. This can lead you with dangling cables if you don’t have exact lengths of cable. Excess cable can waste time and money, and will make your rack installs look messy. The Neat Patch cable management unit is designed to be used with any length of cable. Excess cable can be stored in the ventilated storage compartment, and only what you need remains
