#OFC24:Rethinking Optical Modules for Liquid Immersion in AI Clusters

Check out OFC Conference and Exposition 2024 videos here: https://ngi.fyi/ofc24ytMany optical components used in data centers, such as transceivers, incorporate free-space gaps in their designs. These gaps enable effective coupling from the laser to the Photonic Integrated Circuit (PIC) and from the PIC to the optical fiber, however, because liquids (including immersion liquids) have a different index of refraction than air, when a traditional optical...

Nokia and Vodafone test L4S over an end-to-end PON

Nokia and Vodafone are testing the viability of L4S technology over passive optical networks (PON).L4S is an acronym for "Low Latency, Low Loss, and Scalable" throughput, a technology standardized by the Internet Engineering Task Force (IETF). It addresses a major cause of high peak latency on the Internet, namely, queuing delays. These delays occur as packets linger in network buffers, such as those in routers and modems, waiting to be sent on.The...
