  • Core Switch Inner Layer

    Core Switch Inner Layer

    A core switch is a high-capacity network switch that functions as a network's backbone or core layer. It's responsible for accurately routing communication among layers and departments of different sections. In a nutshell, it helps convey vast chunks of data at greater speeds. Engineered to aggregate massive volumes of data from distribution switches, it provides ultra-low latency and maximum throughput to ensure uninterrupted routing and packet. Its primary function is to rapidly forward data packets between different aggregation switches and, ultimately, to the internet. Unlike access switches, which connect directly to end-user devices, the core switch focuses on aggregating and routing traffic between other switches, minimizing latency. The hierarchy Ethernet network is a three-layer integrated setup of networking devices. Its main concern is providing connectivity.

  • How much of the inner core layer needs to be stripped during optical cable splicing

    How much of the inner core layer needs to be stripped during optical cable splicing

    An optical fiber stripper is designed to remove these buffer and acrylate coatings, typically from a 250µm or 900µm diameter down to the 125µm cladding. This process is a critical prerequisite for both fusion splicing and connector termination. The operation and skills of fiber optic fusion splicing technology can be mainly divided into five steps: fiber stripping, fiber cutting, fiber melting, fiber sleeve, and fiber winding. And tools used for fiber fusion: fusion splicer; fiber cleaver; cable stripper; fiber optic stripper; alcohol;. Let's explain a little about common layers, and what's important to consider when stripping. Stripping: refers to the fiber optic cable in the fiber optic core stripped out, which includes the outermost plastic layer, the middle of the steel wire, the inner layer of plastic and fiber. Fusion Splicing means securely connecting two optical fiber cables by heating their core end faces and pushing them together to fuse them as a spliced single fiber that can transfer light signals with near zero loss at the splicing point. The two fibers are illuminated from two directions, 90 degrees apart.
