A wide range of cloud and video applications, together with the increased access speeds enabled by 5G, DAA, and next-generation PON, are driving the need for ever more optical bandwidth. To deliver this bandwidth, optical vendors are developing a broad range of coherent optical transceivers addressing different segments of the market, each with its own set of design considerations.

100GBaud+ Silicon Photonics Solutions Drive Optical Network Evolution

This paper describes how silicon photonic (SiPh) opto-electronic integration and packaging, with its improved RF performance, is designed to enable next-generation coherent transmission beyond 100Gbaud and provide network operators with the ability to avoid “half-step” capacity upgrades and allow them the full step upgrades they need without sacrificing reach or stranding network bandwidth when migrating from current-generation solutions.

Pass the test

Keely Portway examines the latest 400ZR implementation agreement and asks, what does it mean for test and measurement?
