Why DCS uses multimode fiber
Multimode fibers are predominantly used within data centers for short to medium range data transmission, characterized by their ability to carry multiple light modes simultaneously. Global Internet Protocol (IP) trafic has been skyrocketing in the cloud and in enterprise data centres (DCs), driven by the growing number of internet users and connected devices, faster broadband access, high-quality video streaming, metaverse connectivity and ubiquitous social networking. While single-mode fiber (SMF) dominates long-distance and carrier-grade infrastructure, multimode fiber remains the most cost-efficient and practical choice for enterprise buildings, campus networks, and modern data centers. Its larger core and compatibility with inexpensive vertical-cavity surface-emitting laser (VCSEL) light sources made it an obvious choice for connecting servers within a cabinet or row.
