What’s next for pluggable coherent optics

 This example and many others like it demonstrate the importance of having choice in pluggable transmission modes to best serve the application at hand. With WaveLogic 6 Nano, which is based on the industry’s first 3nm coherent ASIC, Ciena will continue supporting a broad range of transmission modes including OIF 800ZR and OpenROADM 800ZR+, in addition to high-performance 800G modes that extend connectivity across more links.

Pluggables or embedded – what’s the best fit?

As pluggables gain traction across an increasing number of network applications, our customers are looking to strike the right balance between deploying pluggables and embedded coherent modems to meet their demands. The incredible  (WL6e), which became commercially available last October, illustrates the ongoing and critical need for embedded coherent solutions. As disclosed in our first fiscal quarter earnings report, Ciena added 20 WL6e customers in the first quarter alone.

Whereas pluggables are optimized for space and power, france telegram data embedded solutions like WL6e—the industry’s only 1.6T coherent modem—are an ideal fit for links that require superior spectral efficiency and/or ultra-high performance. Our experience with a diverse range of network operators shows many subsea, long-haul, and regional applications where WL6e’s raw capacity, spectral efficiency, and sustainability advantages result in higher performance and lower total cost of ownership than pluggable alternatives.

Simply put, there is no one-size-fits-all approach to solving the increasingly complex scaling challenges faced by network operators. As a leading innovator in embedded and pluggable solutions, Ciena works with you to match the best solution to your needs.

There’s more to plugs than plugs

One of the most anticipated (yet not fully realized) benefits of pluggables is the ability to deploy them in a standards-based, interoperable manner, enabling network operators to use the best pluggable in the host system they prefer. Despite progress towards this goal, hurdles remain with respect to provisioning, troubleshooting, and optimizing performance over converged networks utilizing pluggables. In addition, some vendors have fallen short of meeting interoperability requirements to either protect their host systems incumbency or to promote non-standard, proprietary solutions that lock in an operator to a single-vendor solution.

At Ciena, we have embraced open interoperability. We have assumed a leadership role in driving the Common Management Interface Specification (CMIS), which provides a standardized interface for the management and monitoring of pluggables within a host router. Beyond CMIS, we have advanced our multi-layer network control solution— (Navigator NCS)—to interoperate with Ciena or third-party pluggables in either Ciena or third-party hosts. Our approach is based on open standards in line with YANG data models, NETCONF protocol, and current IETF drafts focused on the management of pluggables in converged IP/optical networks. Standing apart from the competition, Ciena has demonstrated in multi-vendor environments.

Porthcurno Museum of Global Communications educates a new generation

  From the arrival of the first submarine telegraph cables to modern cables implementing the latest in coherent fibre-optic transmission technology,   PK Porthcurno, Museum of Global Communications   is dedicated to preserving and showcasing the significant and historical role Porthcurno plays in global telecommunications. The Museum is a learning hub explaining the evolution of telecom systems that have and continue to shape our increasingly digital world. The historical significance of Porthcurno Porthcurno became a critical site for international telecommunications in the 19 th  and 20 th  centuries. In 1870, the first submarine telegraph cable was laid between Porthcurno and India, marking the beginning of a long history of technological advancements at the UK site. This cable transformed how people communicated across continents, allowing instant communications for the first time – the “ instant messaging ” of the time. The telegraph cable was a milestone f...

Automate network operations smarter and faster with agentic AI

  AI is at the forefront of the technology market sector these days. Research & Development companies are producing more powerful GenAI models, and new companies are appearing on the scene (witness DeepSeek). Global content providers and service providers aren’t standing still either. They are rearchitecting and scaling their networks to ensure they can accommodate the requirements that AI demands: Hyper-connected hyper-powerful GPU clusters for the  training  of Large Language Models (LLMs) High-bandwidth connectivity for real-time  inferencing  to respond to user’s queries In addition, global content and service providers are exploring how  AI can be leveraged to improve and accelerate their network operations – so called AIOps. In   a previous blog , I discussed some high-runner use cases with Ciena experts. In general, AI, Machine Learning (ML), and GenAI can be applied to three key areas to empower network operations teams: Assurance Optimizat...

connectivity opportunities for network operators

  Despite the current hype associated with the network impacts of AI, AI-driven traffic is still in its early days and not yet substantially augmenting data flows outside of data centers. However, additional connectivity capacity will be vital to sustain the growth of AI infrastructure and the evolution of AI models and applications. Securing such capacity is an integral part of investments that are already underway, creating tangible opportunities for network operators aiming to monetize AI demand. Now is the time to set out for success in AI infrastructure connectivity. AI compute growth will translate into a 200-fold increase in power requirement “ Deep learning worked, got predictably better with scale, canada telegram data and we dedicated increasing resources to it. ” Sam Altman’s words appropriately summarize the impressive evolution of AI models and its supporting infrastructure in recent years. Hyperscalers and AI powerhouses are investing billions of dollars to...
