Bringing an open optical network to life: tales from the field

Open optical networking (OON) is an increasingly popular networking approach where the optical terminals are decoupled from the line system, enabling operators to operate optical signals generated by transceivers from multiple vendors over a dense wavelength-division multiplexing (DWDM) open line system from a different supplier. OON allows network operators to become more competitive, enabling vendor choice that supports a more resilient supply chain, faster access to innovation, and improved economics.With a growing number of high-performance coherent optical pluggables on the market that can be equipped directly in switches and routers in IP over DWDM (IPoDWDM) deployments. These bypass the traditional use of transponders, streamlining architecture and lowering costs.

Several factors influence the decision to split nodes in MDU cable infrastructures, including network capacity, subscriber density, signal quality, and cost efficiency. Network capacity refers to the ability of the infrastructure to handle increasing data traffic and bandwidth demands. Subscriber density plays a crucial role in determining the optimal node splitting strategy, as higher concentrations of users may require more nodes to maintain service quality. Signal quality is another key consideration, as splitting nodes too frequently can lead to signal degradation and service interruptions. Finally, cost efficiency is a significant factor, as operators must balance the benefits of improved performance with the expenses associated with node splitting and maintenance. By carefully evaluating these factors, operators can make informed decisions about when and how to split nodes in MDU cable infrastructures.
