Power over Ethernet (PoE) is a technology that allows network devices to be powered over the same Ethernet cable that carries data. This eliminates the need for separate power cables and power sources, simplifying installations and reducing cable clutter. There are three main PoE standards: •PoE (802.3af):This is the original PoE standard and provides up

If you’ve ever had to connect devices using copper or fiber optic cables, you’ve probably encountered an SFP port. Despite their small size, these neat little slots facilitate a lot of heavy lifting in the world of data communications. In this blog post, we’ll answer the following questions: Table of Contents What is an SFP

As data center bandwidth demands grow exponentially, choosing the right high-speed transceiver is critical. Here is a comparison of two dominant form factors: QSFP28 (Quad SFP28): Used for 100G Ethernet, 4 channels of 25Gbps each. Widely deployed in current-generation data centers. Power consumption around 3.5W per modul. QSFP-DD (Quad SFP Double Density): Used for 400G

Choosing between an industrial switch and a commercial (office-grade) switch depends on your deployment environment. Here are the key differences: Operating Temperature: Industrial switches work from -40C to 85C; commercial switches typically 0C to 40C.Mounting: Industrial switches use DIN rail mounting for cabinets; commercial switches use rack or desk mount.Power Input: Industrial switches support redundant

DAC (Direct Attach Copper) and AOC (Active Optical Cable) are two popular connectivity solutions for data center top-of-rack switching. DAC Cables: Copper cable with transceivers permanently attached at both ends. Cost-effective for short distances (up to 7m). Passive design requires no power. Avai. AOC Cables: Optical cable with embedded transceivers. Supports longer distances (up to

GPON (Gigabit Passive Optical Network) and EPON (Ethernet Passive Optical Network) are two competing PON technologies used for FTTH (Fiber to the Home) and FTTx de. GPON (ITU-T G.984): 2.488 Gbps downstream, 1.244 Gbps upstream. More widely deployed in Europe and Middle East. Supports TDM (Time Division Multiplexing) for voice. EPON (IEEE 802.3ah): Symmetric 1.25
