Such submarine cable upgrades will create new revenue opportunities for SONET vendors.
Synchronous Optical Network Market Trends:
- Integration with Packet-Optical Transport Systems: Packet-optical transport systems (P-OTS) allow transporting data traffic seamlessly over optical networks. P-OTS leverages benefits of both SONET/SDH TDM networks and packet networks. SONET systems are increasingly integrated with P-OTS to enable service providers to handle diverse traffic formats over converged networks. In March 2022, Infinera expanded its P-OTS portfolio with metro packet-optical transport solutions having 200G coherent optical technology. The integration of SONET and P-OTS allows operators to optimize network efficiency.
- Adoption of Software-Defined Networking: Software-Defined Networking (SDN) and Network Function Virtualization (NFV) technologies are seeing increased adoption in telecom networks. SDN-enabled SONET equipment provides greater network agility, flexibility and programmability. For instance, Lumentum launched its SDN-enabled SONET platform in 2018 that allows programmable optical layer automation. The shift towards software-defined SONET networks is a key trend.
- Use of Machine Learning in SONET Systems: SONET equipment vendors are integrating machine learning (ML) capabilities in their systems to enable self-organizing networks. ML algorithms help SONET networks to automatically predict and resolve issues through continuous learning. In 2019, Ciena launched its Adaptive Network solution that leverages AI/ML to provide greater network visibility and performance insights to operators and allow networks to self-optimize. The adoption of ML is transforming SONET networks to be more resilient and efficient.
- Increasing Deployments of 100G+ SONET Systems: Growing bandwidth demand is driving operators to deploy next-gen ultra-high capacity SONET systems supporting 100G, 200G and 400G line rates. 100G SONET was standardized in 2016 under the name OTU4. Ciena's WaveLogic 5 platform provides programmable 200G-800G coherent optics to power high-speed optical networks. The transition to 100G and beyond speeds will be a key technology trend in the SONET market.

Synchronous Optical Network Market Restraints:
- High Cost of Deployment: The biggest challenge impacting SONET adoption is the high cost associated with deploying and managing SONET equipment. The optical line terminals (OLTs), optical network units (ONUs) and other hardware are expensive. Constant upgrades are required to support evolving technologies like 5G. Operators need skilled manpower for deploying and maintaining SONET networks which further adds cost.
- Long Gestation Period for Returns: The initial upfront investment for setting up SONET networks is very high. Operators also need to regularly upgrade the network infrastructure to keep up with growing demands which entails additional capex. Due to the substantial initial investment, the ROI realization period is lengthened. This can act as an impediment for service providers.
- Growing Competition from Alternative Technologies: Emerging technologies like carrier Ethernet and MPLS networks are being increasingly adopted by operators as they are easier to deploy and manage compared to SONET. Even legacy networks like asynchronous transfer mode (ATM) pose competition. The availability of such alternatives at a lower cost than SONET is impacting its adoption among price-sensitive customers.
