Coherent optical data transmission is expanding from low-volume niche applications, such as long-haul networks where performance is more important than cost, to high-volume applications such as metro networks, data center interconnects (DCI) and even access networks. Current proprietary and non-interoperable solutions for long-haul networks do not meet the requirements for metro, DCI and access networks, where low cost and low power are the primary design goals. Interoperability is part of the solution as it promises higher acceptance, higher volumes, and a more secure supply of transceivers at a lower price point.
