IntroductionAs businesses, cloud providers, and telecom operators continue to face exploding traffic demands, 100G networking has become the new standard. The QSFP28 port is at the heart of this transition. Compact, powerful, and flexible, it enables 100G Ethernet links using four 25G lanes.QSFP28 ports are now wide...

IntroductionThe explosive growth of cloud computing, AI, 5G, and high-performance computing (HPC) is driving networks to move from 100G to 200G and 400G—and soon to 800G. To meet this demand, network operators need optical modules that deliver higher bandwidth, better density, and backward compatibility with existin...

Introduction: why compare SFP and QSFP?In modern data centers and enterprise networks, choosing the right pluggable transceiver form factor is critical. Two of the most common are: SFP (Small Form-factor Pluggable) QSFP (Quad Small Form-factor Pluggable) Both are compact, hot-swappable ...

IntroductionIn modern data centers and enterprise networks, Quad Small Form-factor Pluggable (QSFP) cables are everywhere. They connect servers, switches, and storage at speeds from 40G to 400G and beyond. Thanks to their four-lane parallel architecture, QSFP cables combine high bandwidth with compact design, helpin...

Introduction: why fiber patch cables matter?In a modern data center, every high-speed optical link depends on the right fiber patch cable. These short fiber optic cords connect transceivers, switches, patch panels, and servers. Without them, even the best optical modules and switches cannot deliver performance.As da...

Introduction: Why talk about AOCs?As data center speeds grow from 10G → 25G → 100G → 400G → 800G, the choices for server-to-switch interconnects become more complex. Today, IT teams typically pick between three options: DAC (Direct Attach Copper) – cheapest, short-distance. AOC (Active Optical Cabl...

IntroductionIn today’s high-speed data centers and enterprise networks, choosing the right cable is critical. While fiber optics get most of the attention, Twinaxial cables (Twinax), especially in the form of Direct Attach Copper (DAC) cables remain one of the most cost-effective and reliable solutions for short-dis...

Introduction: Why Upgrade Speeds MatterModern workloads such as AI training, cloud computing, video streaming, and HPC (high-performance computing) are pushing networks harder than ever. If the network cannot keep up, servers and GPUs sit idle waiting for data.This is why many IT teams are planning their upgrade pat...

Introduction: Why Form Factors Matter?In the world of 400G and 800G networking, performance is not only about speed but also about form factor - the physical shape and design of the optical module. The form factor determines: How many ports fit on a switch faceplate. How much heat each port can handl...

Introduction: Why 400G and 800G Matter?The rise of AI training, HPC (high-performance computing), and hyperscale cloud services has pushed network bandwidth demands higher than ever. Ten years ago, 40G and 100G were cutting-edge. Today, many data centers are already migrating to 400G, and some are planning or testin...
