Fiber Optical Communication

Taking full advantages of low cost, high reliability, fast installation, easy maintenance and scalability, Etheet Network becomes a very popular and commonly used LAN technology that has been developed for over 40 years and gets mature day by day. Under its continuous advancement and improvement, the data transmission rate has been increased greatly which causes the emergence of 10G, 40G, 100G and even 120G Etheet Network. Among these kinds of Etheet Network, there is no doubt that 10G Etheet Network has become a commonplace for current network backbones, data centers, and server farms, supporting high-bandwidth, mission-critical applications. In this article, it will talk about why 10G Ethe...

When choosing QSFP+ transceivers for designing 40G Etheet network, you may hear the descriptions like ldquo;Single-mode QSFP+rdquo;, ldquo;Multimode QSFP+rdquo;. Are you familiar with these modules? What do these words stand for? Whatrsquo;s the difference between these two QSFP+ modules? Which one should you choose to deploy your 40G Etheet network? And what should be noticed when using them? In fact, the words single-mode and multimode here mean the different types of optical fibers that QSFP+ transceivers work with. For instance, single-mode QSFP+ means that QSFP+ transceivers run through single-mode fibers (SMF), while multimode QSFP+ will work with multimode fibers (MMF). In this articl...
