Many hardware vendors like Cisco, Finisar, Huawei and Brocade have recently announced support for 100 Gigabit Ethernet and telecom vendors around the world have also shown interest in launching 100G networks. All these events shows the sign of the advent of 100 Gigabit Ethernet in the commercial segment. However, is it necessary to move to 100G now?
Over the years, there has been an unprecedented increase in network connectivity and bandwidth needed to accommodate workload requirements of cloud computing, and high-performance web services. The rapid advancements in fiber optic technology has enabled easy upgrading from 10GbE to 40/100GbE within the data centers. With the emergence of 100GbE technologies, the creation of data center network architectures free from bandwidth constraints has been made possible. Among 100G interconnect components, QSFP28 transceiver is the predominant form factor for 100G switching and routing connectivity, a key enabler as 100G begins to ramp in data centers.
