  • How to connect fiber optic and coaxial cables to a switch panel

    How to connect fiber optic and coaxial cables to a switch panel

    Most modern fiber-enabled network switches require an SFP transceiver module featuring a duplex (two strand) multimode OM3 or duplex single mode OS2 connection with LC connectors. Direct attach cables with pre-terminated SFP connections may also be used. These methods can also be used to run your home network over fiber optics. Fiber optic technology is widely used in networking due to its high-speed data transmission capabilities and long-distance coverage. SFP transceiver modules almost always require two fiber optic cable strands.


  • Classification of Building Electrical Distribution Boxes and Switch Boxes

    Classification of Building Electrical Distribution Boxes and Switch Boxes

    Electrical boxes are classified by multiple dimensions, not just shape. Common categories include box shape, device function, installation environment, gang size, and material. Shape helps identify where a box is used. At its core, a distribution box, also known as a distribution board, panelboard, or fuse box, is a protective enclosure that houses all the electrical components that control and protect the circuits in a building. From powering homes and industrial facilities to supporting medium-voltage infrastructure, these enclosures ensure safe, efficient, and reliable power distribution. Rectangular boxes are typical for outlets and switches, while round or octagon. For procurement professionals, electrical contractors, and project managers, choosing the right Distribution Box (DB Box) is a critical decision that directly impacts system safety, reliability, and long-term operating costs.
