Abstract
Around 30%-40% of intra-datacenter connections still rely on vertical cavity surface emitting lasers (VCSELs) and multi-mode fibers (MMFs), generally legacy OM3 and OM4. However, the next-generation systems will require transmission throughputs above 100G/lane, with targets towards 200 G/lane. An open discussion is undergoing whether VCSEL-MMF technology is still suitable, so in this paper we discuss the challenges and the solutions for high-speed intra-datacenter connections.
