Delivering power-efficient, compact optical links optimized for short-reach AI/ML datacenter interconnects, this 1. 6T (32x50G) array is designed for scale-up networks, enabling low latency, cost efficiency, and seamless migration to Near-Packaged and Co-Packaged. SAXONBURG, PA, March 28, 2025 (GLOBE NEWSWIRE) – Coherent Corp. (NYSE: COHR), a global leader in photonics, announces general availability of the industry's first 100G ZR QSFP28-DCO featuring 0dBm optical output power, designed for metro and regional ROADM-based line systems. The new 100G ZR. Cisco® QSFP28 100G ZR extends 100GbE coherent links from QSFP28 ports reaching up to 80km over dark fiber and up to 300km over amplified Dense Wave Division Multiplexing (DWDM) links. While 100G remains the workhorse for enterprise edges, the core data center has rapidly migrated to 400G (QSFP-DD) and is actively piloting 800G deployments. From the large GBIC in 1995 to today's nano-scale QSFP-DD and co-packaged optics (CPO), how has packaging technology advanced? This guide explains the evolution of optical module packaging in plain.
