  • What switch should I use for a 300Mbps fiber optic broadband connection

    What switch should I use for a 300Mbps fiber optic broadband connection

    If you're selecting fiber optic switch modules for 2026, I recommend considering options like the ipolex 10G SFP+ LR for high-speed links, the TP-Link MC220L for versatile media conversion, and Estink's Ethernet fiber switch for seamless integration. A network switch with fiber uplinks lets you break past the 100-meter limit of copper Ethernet, connecting distant buildings, server racks, or high-bandwidth cameras with zero signal degradation. The real challenge is picking the right port count, SFP speed tier, and management features without. When it comes to transmission speeds, fiber switches can operate at different standardized speeds. Examples of these are 1 Gbps (Gigabit Ethernet), 10 Gbps (10 Gigabit Ethernet), 40 Gbps and even 100 Gbps.

  • How to ping continuously on the core switch

    How to ping continuously on the core switch

    To initiate a continuous ping, you need to use the ping command with specific parameters. The most basic form involves adding the -t switch followed by the target IP address or domain name. This article will help network administrators with some handy tips on using PING feature set in Cisco, Juniper, Windows and MAC devices. Unlike a standard ping, which sends a set number of packets, continuous ping keeps sending packets. Constantly pinging an IP address is a common network troubleshooting technique used by IT professionals and cybersecurity experts to monitor the availability and responsiveness of a device or server. 3 with a repeat a count of 500. 3 repeat 500 but keep getting the error % Invalid input detected at '^' marker.

  • How to use a fiber distribution box to splice a pigtail machine

    How to use a fiber distribution box to splice a pigtail machine

    Fusion Splicing – Join incoming fiber strands to pigtail terminations inside the FDB, fusing together using a fusion splicer. Field-terminating connectors is a meticulous, high-pressure process where even a tiny mistake can force you to cut the fiber and start all over again. If you're new to fiber optics or want to enhance your technical skills, this guide will help you understand how to splice fiber pigtails safely and efficiently. A fiber pigtail is a specific hardware connection used for cable termination. Thus, a fiber termination box is used to terminate the optical fiber. This guide covers everything: what fiber optic pigtails are, how they differ from patch cords, which connector and polish type to specify, how to choose between mechanical and fusion splicing, and the real-world applications where pigtails are the right call.
