Reach to 40km Transmission – 100G QSFP28 ER4 Lite Module

Today’s world is undergoing an infrastructure transformation, which requires higher speed, greater scalability, higher performance, flexibility, and reliability to meet the demands. Take 100G data rate as an example, the MSA groups keep driving the development of 500m, 2km, 10km and 40km cost-effective 100G optics targeting modern data center. The 100G QSFP28 ER4-Lite standard was sampling several months ago, but…


Introduction to 10GbE/25GbE/40GbE/100GbE Fiber Optic Cabling

Technology is changing rapidly. Just when you got used to Gigabit Ethernet speeds being a fast & reliable system, someone unveiled 10GbE, 25GbE, 40GbE or even 100GbE systems a few years later. The newer and higher performing iterations are indeed the great breakthrough for the telecommunication industry, but also pose difficulty in choosing network migration path—10G to 40G to 100G,…
