  • Can a loop cause the core switch to lose network connectivity

    Can a loop cause the core switch to lose network connectivity

    Network loops can occur when multiple network switches are incorrectly configured, creating redundant paths between switches that allow Ethernet frames to loop endlessly. This can lead to network congestion, packet loss, and even a complete network failure. All endpoints and servers/printers are on a single VLAN. This just started happening a few days. There are basically two things that can happen, a layer 2 loop or a layer 3 loop. If STP doesn't work. What would happen, if anything at all, if I were to connect an unmanaged network switch to itself with a normal Ethernet cable? If I had an 8-port unmanaged switch and I plug one end of an Ethernet cable into port 1 and the other end into port 2. This would be a consumer level switch, the kind. Network loops occur when there are multiple paths between two points in a network, leading to data continuously circulating and potentially causing significant issues such as performance degradation, unexpected port blockages, complete network outages, and device crashes.

  • Selection Guide for Smart City-Grade Active Optical Devices QSFP-DD

    Selection Guide for Smart City-Grade Active Optical Devices QSFP-DD

    This guide explains how to choose QSFP-DD transceivers step by step, helping you avoid costly mistakes and ensure compatibility across your network. Last March, a mid-sized cloud provider ordered 400 QSFP-DD SR8 modules for a new data center. While their switching platform and target speeds were correct, they overlooked a key detail: connector type. QSFP-DD (Quad Small Form-Factor Pluggable Double Density) transceivers double the number of high-speed electrical interfaces in QSFP to achieve 400G Ethernet speeds – and double them again to reach 800G. As a. While 100G remains the workhorse for enterprise edges, the core data center has rapidly migrated to 400G (QSFP-DD) and is actively piloting 800G deployments. For network engineers and procurement managers, the challenge isn't just bandwidth—it's interoperability, thermal management, and selecting. An engineer-focused, “just tell me what to choose” guide to transceiver selection with architecture, power budget, compatibility, and upgrade plan — designed for 25G/100G today and 400G/800G tomorrow.

  • Can fiber optic cables be used with network panels

    Can fiber optic cables be used with network panels

    Fiber optic cables are widely used in structured cabling systems to connect network devices such as transceivers, switches, and patch panels. A single strike can trace its way through your home or office's coax and copper Ethernet network cables. In many cases, this can instantly destroy all. A fiber patch panel is a mounted enclosure—either rack-mounted or wall-mounted—used to terminate, manage, and interconnect multiple fiber optic cables. A bulk (multi-strand) fiber cable enters the patch panel and then each fiber strand is separated into individual strands or pairs of strands. These individual strands will then connect to electronic devices. A fiber optic cable is a transmission medium that uses strands of glass or plastic fibers to carry data as pulses of light.
