Whether you operate metro networks as a service provider or have a regional backbone network as a small carrier, embracing a more open approach to networking has become increasingly crucial. This adaptable networking trend, also known as open optical networking or disaggregated networking, is gaining momentum due to its potential to enhance capacity, flexibility, and cost efficiency, especially with advancements like 400ZR technology.
Consequently, the implementation of 400ZR raises important questions about how to structure and upgrade networks to fully leverage its capabilities while maintaining cost-effectiveness. Additionally, managing a more disaggregated network is important to consider consideration.
To sum up, the demand for increased capacity at reduced costs makes adopting a more open and flexible networking approach imperative. Let’s delve into the specific questions surrounding the optimisation of networks and the effective management of this disaggregated model.
Enhanced Capability at a Reduced Expense
As consumer broadband consumption continues to rise and businesses adopt new 5G-dependent technologies, many carriers are realising that their current regional and metro network capacity is insufficient. Simultaneously, declining margins on subscriptions demand the need for more cost-efficient networks to stay competitive. To meet these challenges and provide faster connections, enhanced features, and increased data capacity to subscribers, continuous innovation is essential.
Recognising the potential of 400ZR, carriers are looking to leverage its benefits to boost capacity and reduce costs. The 400ZR-compliant optics offer the advantage of being used in low-cost 100G mode (100G IP over DWDM) and at 400G, making it an attractive option for metro and regional networks with high-capacity demands but not requiring the same performance as long-haul networks. Utilising optical networking equipment designed specifically for long-haul usage may not be the most cost-effective solution for carriers.
As you search for the best path to structure and upgrade your network, optimising the cost per GB becomes a key priority. Embracing 400ZR technology appears to be a promising way to address both capacity expansion and cost-efficiency concerns, ensuring your network remains competitive in the ever-evolving telecommunications landscape.
Improving The Efficiency Of Traffic Flows
For decades, both metro and regional networks have followed a traditional structure, characterised by a significant reliance on transponders. However, these transponders might not always provide a noticeable advantage when compared to alternative options.
Additionally, the use of proprietary line systems means carriers must pay licensing fees to vendors every time they activate a new wavelength channel. Consequently, accommodating growth and adjusting networks to changing consumption patterns comes at a considerable expense.
Forward-looking operators seek more flexible approaches to enhance traffic flow efficiency. One promising solution is adopting open line systems, which offer greater freedom to customise traffic flows. By strategically placing ROADMs (Reconfigurable Optical Add-Drop Multiplexers) along the network, operators can modernise and optimise metro and regional networks. This progressive approach is popular due to its ability to leverage high-capacity, cost-effective technologies such as 400ZR, maximising network capabilities.
How to Achieve a Seamless Transition to 400ZR
When transitioning to 400ZR, the choice between rebuilding or restructuring your network may leave you wondering how much of your existing equipment needs replacement. Upgrading everything at once can be costly and inefficient. To address this, a growing trend favours enabling 400ZR on existing line systems and routers. This approach allows you to upgrade essential network elements without the need to replace everything else.
Moreover, opting for a disaggregated regional or metro network provides practical advantages. You can achieve higher capacity at a lower cost by freely mixing and matching network elements from different vendors. This freedom lets you select components that offer the best value for money without being tied to an all-in-one solution. Additionally, building your network with elements adhering to open standards and capable of interoperating with other vendors’ products ensures a future-proof infrastructure and maximises return on investment.
Simplifying The Management Of Decentralised Networks
If you are considering the adoption of disaggregated regional or metro networks to enhance flexibility and achieve higher capacity at a reduced cost, then the management of these networks might be a concern for you. Dealing with multiple vendors can complicate things when it comes to addressing failures. As part of the broader effort to optimise cost efficiency, many service providers are seeking ways to streamline the management of their regional and metro networks.
In this context, there is a growing trend towards consolidation, automation, and simplification of network management. The demand for more flexible networking options has significantly increased in recent years, leading to the development and advancement of open management solutions. Embracing an effective multi-vendor management solution can greatly simplify troubleshooting, streamline network operations, and overcome the main challenge of adopting flexible networking.
