    Dealing with Impedance Mismatching

     

    When selecting coax cable or certain types of coaxial connectors and adapters there are a variety of factors to consider such as jacket type, shielding, and loss.  Today we want to focus on impedance, specifically what to do if you encounter differing impedances.

    In coax, there are two categories of impedance 50 Ohm and 75 Ohm.   Ohm is the measurement of electrical resistance.  The physical properties of the cable determine if it's impedance.  The hallmarks of 50 Ohm coax are high power handling and low attenuation and are used in RF applications.  75 Ohm coax is designed for low power, signal transmission efficiency, which is typically used in audio/video applications.

    As the need for bandwidth speed outpaces the capabilities for physical expansion, networks are evolving by offering higher density higher throughput solutions. This allows for increased data rate performance without having to invest in new physical locations. MPO cables provide high-density termination capabilities and are an ideal choice for delivering the fastest link and enabling high-speed interconnects.

     

    Multi-fiber push-on connectors (MPO) are multi-fiber cables terminated in a single connector. They are typically available in 8, 12 or 24 fibers and are common for data center and LAN en- environments. They ease cable management and allow faster deployment in duplex 10 Gig fiber applications.
