Introduction to 100G Single Lambda Transceivers

Introduction 100G Single Lambda transceivers were defined by 100G Lambda MSA (100G Lambda Multi-Source Agreement). The MSA 100G MSA uses 100G PAM4 optical signaling and encoding it is able to use 100Gb/s per channel to transmit from 2m up to 40KM via single-mode fiber. Advantages The traditional 100Gb/s optical standards such as 100GBASE LR4, 100GBASE […]
