Building upon its first-to-market 400G EML and PD debuted at OFC 2025, Broadcom is launching the Taurus BCM83640, the industry's first 400G/lane optical DSP optimized for 1. With 400G modules now the baseline, 800G adoption is surging—especially across AI and hyperscaler environments—while 1. This article unpacks the technologies powering this leap (silicon photonics, advanced modulation, and co-packaged optics), compares deployment. In this blog, Brodie Gage explores how distributed AI training is reshaping optical infrastructure—and details how Ciena is advancing the coherent and photonic innovations powering. 400 Gigabit Ethernet (400G) transceivers are optical modules capable of handling data rates of 400 Gbps. This shift is driven by multiple forces: hyperscale data centers require greater east-west bandwidth to support massive internal data.
