    The popularity of Power over Ethernet (PoE) is growing. Since it was introduced in 2003 as a way to both transmit data and deliver power on a computer network, the PoE market has reached $2 billion. It is expected to hit $3.2 billion by 2030, according to market analysis firm Market Research Future.

    Two key devices on a PoE network are splitters and injectors. A PoE splitter allows a PoE-enabled Ethernet cable to be split into separate power and data cables. A PoE injector injects electricity onto an Ethernet cable to supply power to PoE-enabled devices.

    This blog post explains what splitters and injectors can do for your PoE deployment. It also covers some terms you will encounter while shopping for splitters and injectors − such as the difference between “mid-span” and “end-span” devices, and the significance of a few key standards that regulate the design of these products.

    But first, in case you are new to the world of Power over Ethernet, let’s start with a summary of what it can do for you.

    Power + Data = PoE

    Power over Ethernet is a technology that allows network cables to carry electrical power along with data, enabling a single Ethernet cable to provide both to a device. It is commonly used to power devices such as wireless access points, IP cameras, and VoIP phones without the need for a separate power supply.

    PoE works by injecting DC power into the Ethernet cable in a way th

  2. Know the RJ45 Color Code for Easy Connections and Repairs

    RJ45 Color Codes Explained

    An RJ45 connector is a modular, eight-position, eight-pin connector used for terminating Cat5e or Cat6 twisted-pair cable. An RJ45 color code or “pinout” is a specific arrangement of wires that dictate how the connector is terminated. Since the color code specifies the order in which the individual wires within the cable should be connected to the pins on the RJ45 connector, knowing the color code is essential when you need to make or repair Ethernet cables.

    There are multiple pinouts for RJ45 connectors, including:

    • Straight-through (T568A or T568B)
    • Crossover
    • Rolled
    • T1
    • Loopback

    Straight-through is the most common type of cable and is used for connecting your computer to your network. The other RJ45 color codes are for specialty cables that are used for unique network applications.

    Within the family of straight-through R45 color codes, there are two standards recognized by ANSI, TIA, and EIA:

    • The T568B wiring standard is seen as the default wiring scheme for twisted-pair structured cabling in the U.S. It uses four pairs of wires, with each pair being a different color.
    • The T568A wiring standard differs from T568B only in the order of the green and orange pairs. However, it has been surpassed by T568B – if you are unsure of which standard to use, choose T568B.

    We recommend using the same wiring scheme on both ends of a cable to ensure proper connectivity.

  3. 6 Reasons Why RCA Cables Are Still Alive and Well

    Think about the types of cables you use to connect your electronic devices. How many of those cable formats were being used 20, 30 or 40 years ago?

    If you come up empty here, let us jog your memory and call attention to the humble but still-relevant composite audio/video RCA cable. These cables with their familiar red, white and yellow connectors continue to provide dependable, cost-effective connections for audio and video devices.

    RCA audio and video cables are not quite as popular as they used to be. In many cases they have been edged out by non-RCA formats, such as HDMI cables. However, RCA remains alive and well. This blog post examines six reasons why they still make sense for many consumers. But first, a little background …

    Composite RCA vs. Component RCA

    The most common composite RCA cables contain either two or three lines. The red and white connectors of a two-line model carry the right and left audio channels of a stereo signal. The added yellow connector of three-line models transmits the video signal.

    A second type of three-line RCA cable has red, green and blue (RGB) connectors on each end. This RGB component RCA cable carries a premium “component video” signal, which does not include audio. It divides the video into three parts: two for color information and one for luma (brightness).

    Now for the six reasons why RCA is still popular.

    1. RCA Cables Are Versatile

    RCA cables transmit audio and/or video signals for a wide variety of equipment.

    • They are used for video signage and video surveillance.
    • They connect laptop and desktop computers to home theater systems.
    • They link some televisions to DV
