  • Principles of Optical Port Network Switches

    Principles of Optical Port Network Switches

    An optical switch is a device that selectively routes optical signals from one fiber to another without converting them into electrical signals. This technology allows for high bit rate transmission to be switched between various optical lines. This is achieved through various optical devices and techniques that can redirect light beams or signals based on specific control. As a leading provider in the field, Guangxi Keyi Optical Communication Technology Co. specializes in delivering high-performance optical switching solutions tailored for telecom operators, data centers, and enterprise networks.


  • Network storms occur when accessing switches

    Network storms occur when accessing switches

    A network loop occurs when redundant connections between switches cause data packets to endlessly circulate, suitable to broadcast storms, high CPU usage, and network congestion. A Broadcast Storm is basically a situation when an abruptly large number of broadcast packets in a very small amount of time. Due to the broadcast storm, the network quality degrades significantly. If left unresolved, network loops can disrupt communication, slow down network performance, and even crash switches or. It starts when traffic is multiplied or repeated faster than the network can process it, and the result is delayed applications, dropped packets, and systems that feel “down” even when they are technically still online. These packets can consume a significant portion of network resources, leading to network slowdowns or even complete network outages.

  • The network cabinet door won t close

    The network cabinet door won t close

    Most doors drift open due to loose screws, misaligned hinges, a tired catch, or a slight twist in the panel. Work in this order: tighten, align, test the closing force, then upgrade the latch if needed. A cabinet door that fails to close completely is a frequent annoyance in kitchens, bathrooms, and utility areas, signaling a functional problem that ranges from simple obstruction to deeper structural issues. This failure not only detracts from the appearance of the cabinetry but also allows dust. Help - can't close my rack door! Can you not move the vertical rails backwards by 50 to 100 mm? It's a pet peeve of me, rack manufacturers always put the default rail position way too much to the front. Even the really expensive ones you'll find in colos. This saved me - didn't realize you could do. In this practical home-repair tutorial, Mike shows how to troubleshoot and fix common cabinet door problems—doors that won't stay closed, swing open on their own, or collide with neighboring doors. Common Causes of Cabinet Doors Not Closing 2.

  • Is fiber optic cable or network cable better

    Is fiber optic cable or network cable better

    Fiber is faster, highly reliable, more durable, and great for cloud-based or real-time work. Cable is cheaper to install and more accessible but can get slower during busy hours due to shared bandwidth and asymmetrical speed. cable internet speeds, reliability, and costs to find the best network connection type for your needs. Learn the pros and cons in this guide. Cable utilizes familiar copper wiring originally built. This guide compares fiber-optic cable and traditional copper internet cable (coaxial cable) across key factors: technology, speed, reliability, and cost in 2025. Plus, it's more widely available than fiber. TechnologyAdvice is able to offer our services for free because some vendors may pay us for web traffic or other sales opportunities. Because data can travel faster across greater distances with glass than with cable, the connection speed is much faster with a 100% fiber-optic network.

  • How Network Cabinets Appear

    How Network Cabinets Appear

    Network cabinet is tall, breathable frame designed to organize various devices efficiently. Its structured layout maximizes floor space and keeps server hardware well-organized. Think of it as the secure, organized, and climate-controlled “nerve center” for your network equipment. So, if you are also looking for network cabinets, then this up-write is definitely written for you. So, keep. In general, smaller or wall-mount racks are suitable for home or office rack installation; while 4-post racks or enclosed server racks are greater for data centers or server rooms. What is a Network Cabinet? A network cabinet houses and organizes. Network cabinets are the backbone of modern IT infrastructure — organizing routers, switches, servers and wiring into secure, cool, manageable racks that enable scalability, efficiency, and hardware protection. Simply put, a network cabinet (or network rack) is a metal enclosure used to hold and. How to Choose the Right Network Cabinet for Your Needs Choosing the perfect cabinet is easy with these steps: Measure Your Equipment: Check the height, width, and depth of your devices.

  • The network cable has a pigtail

    The network cable has a pigtail

    They are the bridge between fiber optic cables in the field and the equipment or patch panels that manage them. By combining factory-installed connectors with spliced bare fiber, pigtails ensure that network installers can create fast, reliable, and cost-effective terminations. Fiber optic pigtail are utilized to terminate fiber optic. The most urgent stage of the process is, in fact, separating fiber optic pigtail, also known as pigtail fiber or pigtail fiber optic cable. These short, pre-terminated cables play a vital role in terminating and splicing optical fibers, especially in complex fiber infrastructure such as data. A pigtail is used to provide fiber optics with a connector.

  • How to solve the problem of no network when connected to a router via fiber optic cable

    How to solve the problem of no network when connected to a router via fiber optic cable

    Restarting your router, checking your modem connection, and resetting network settings often resolve the problem quickly. Why Do Fiber Networks Fail? Despite their robustness, fiber networks can fail due to:. This connected but no internet error means your device has successfully authenticated with your router and received an IP address, but it cannot reach anything beyond your local network. The problem affects Windows PCs, Macs, iPhones, Android phones, and every other WiFi device equally. First, check the basics—look for power issues on your optical network terminal and inspect all cables for visible damage. Many fiber internet problems come from dirty connectors or loose plugs, not major faults.
