High Bandwidth Density Each module supports 400 Gbps via 4×100Gbps or 8×50Gbps lanes, enabling dense connectivity without increasing port counts. PAM4 (4-Level Pulse Amplitude Modulation): This is the predominant modulation technique used in 400G modules. From cloud data centers to metro and long-haul networks, 400G—particularly coherent variants like ZR and ZR+—is helping eliminate bandwidth bottlenecks and support the growing demands of AI, big data, and next-generation digital services. With 400G modules now the baseline, 800G adoption is surging—especially across AI and hyperscaler environments—while 1. 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. 🔍 What Is a 400G Optical Module? A 400G optical module performs photoelectric conversion: With a 400 Gbps transmission rate, these modules support industry evolution from 100M → 1G → 25G → 40G → 100G → 400G → 1T.
