    The difference and purchase of network management switch and non network management switch
    • July 23. 2021

    In this article, ETU-LINK will take you to talk about network management switches and non network management switches. With the development of the network, the demand for switches is also increasing. Many switch parameters will be written with network management switches or non network management switches. What is the difference between the two?   The non network management switch is also kno...

  • Active cable ACC—Enhanced version of DAC high-speed cable
    Active cable ACC—Enhanced version of DAC high-speed cable
    • July 21. 2021

    As we all know, DAC active cable is mainly used for interconnection between cabinets. Due to the limitation of passive copper cable DAC transmission distance due to material, high frequency loss of connector and other factors, the maximum length of passive copper cable DAC with transmission rate of 10G/25G can only reach 7m, and the maximum length of passive copper cable DAC with transmission rate...

    Application of optical fiber patch cord and precautions for use
    • July 13. 2021

    The application of optical fiber patch cord is more and more widely, and it is often used in communication room, local area network, cable TV, light into the home and other system networks, but it is relatively fragile, so we need to be extra careful when wiring. So how should the optical fiber patch cord be connected? And what are the precautions in the use process?   Optical fiber patc...

  • Optical fiber test method
    Optical fiber test method
    • July 09. 2021

    Optical fiber testing is divided into primary testing and secondary testing. The primary testing is also the basic testing. It mainly tests the insertion loss (that is, attenuation) of the optical fiber and the length of the optical fiber link. No matter it is single-mode fiber or multi-mode fiber, they are all made of glass fiber, and natural loss will inevitably occur when optical pulse sig...
