What’s really inside a coherent transceiver? These tiny pluggables do a massive job. In this image, I opened up a coherent pluggable transceiver and paired it with a block diagram that shows what’s happening inside from electrical DSP to optical signal output. Here’s the breakdown: 1. Digital Signal Processing (DSP) handles advanced modulation and error […]
Layer 2 Switch vs Layer 3 Switch – What’s the Difference? Many people ask: What’s the real difference between a Layer 2 and a Layer 3 switch? ✅ Layer 2 Switch -Works with MAC addresses -Sends data within the same network (LAN) -Does not support routing between networks -Used for connecting devices like PCs and […]
Don’t Ignore the Lights! Understanding Indicator Lights on Routers & Network Switches In many organizations, the blinking lights on network switches and routers are often overlooked—until something goes wrong. But these tiny LEDs are powerful first-level troubleshooting tools that can save time, reduce downtime, and guide quick diagnosis of network issues. Here’s what they tell […]
Manageable vs. Unmanageable Switches – What’s the Difference? When building a reliable network, choosing the right type of switch is crucial. A manageable switch offers advanced features like VLAN configuration, traffic monitoring, port mirroring, SNMP support, and remote access via web or CLI. These switches are ideal for enterprise environments where performance, security, and control […]
What is SFP? SFP stands for Small Form-factor Pluggable. It is a compact, hot-swappable transceiver used for both optical and electrical connections in networking hardware. It connects a switch, router, or other network device to a fiber optic or copper networking cable. SFP, or Small Form-factor Pluggable, is a compact and hot-swappable transceiver used in […]
Know the difference between L1, L2 and L3 Switches As a System & Network Administrator, working across different layers of the OSI model is part of daily operations. Here’s a quick breakdown: L1 (Physical Layer): Basic switching with no MAC address awareness. Think of media converters or hubs. L2 (Data Link Layer): Understands MAC addresses, […]
Unlocking the Power of SFPs (Small Form-factor Pluggable) Transceivers: A Quick Guide! In today’s high-speed networking world, SFPs transceivers are essential for ensuring smooth data transmission across fiber optic and copper cabling. From small-scale businesses to large enterprises, SFPS transceivers are integral in connecting networking equipment for optimized performance. What is SFP? SFP transceivers are […]
A switch is a networking device that connects multiple devices within a network and directs data only to the intended destination. Switch Ports and Their Types 1. Ethernet Ports Fast Ethernet (10/100 Mbps) – Supports speeds up to 100 Mbps. Gigabit Ethernet (10/100/1000 Mbps) – Supports speeds up to 1 Gbps. 10-Gigabit Ethernet (10 Gbps) […]
What is a Network Switch? A switch is a fundamental networking device that connects multiple devices within a network, allowing efficient data transfer between them. Unlike hubs, switches operate at the data link layer (Layer 2) and use MAC addresses to intelligently forward data to the correct destination. How Does a Switch Work? ✅ MAC […]
