  • Fiber Optic Cable Junction Method

    Fiber Optic Cable Junction Method

    Fiber optic joints or terminations are made two ways: 1) splices which create a permanent joint between the two fibers or 2) connectors that mate two fibers to create a temporary joint and/or connect the fiber to a piece of network gear. Active connection utilizes various fiber optic connectors (plugs and sockets) to connect site-to-site or site-to-cable. This method is flexible, simple, convenient, and reliable, commonly used in building computer network cabling. The typical attenuation is 1dB per connection. There are two primary. Fiber optic splicing is the process of joining two optical fibers end-to-end. Another method of connecting optical fibers is termination or connectorization, which consists of processing the end of a fiber optic bundle so that it can be connected to other fibers or devices through fiber optic. Fiber optic cable mechanical splicing is an alternate splicing technique that does not require a fusion splicer.

  • What size cable tray should be used for wiring in the workshop

    What size cable tray should be used for wiring in the workshop

    Best Size: Here, deep trays (75mm to 150mm) are used since power cables are typically thick and heavy. Data cables, such as your Wi-Fi or computer ones, are extremely sensitive. They do not get hot; however, they do not like to hang or sag. In practice, cable tray dimensions are a system of interrelated measurements —width, depth, length, and material thickness—that directly affect cable fill compliance, heat dissipation, structural loading, and long-term expandability.
