Our Networking team's highlights from an exciting week in San Diego.

2025 has been a pivotal year for Nokia, headlined by the acquisition of Infinera, the rollout of highly-anticipated hardware updates and an all-new Documentation AI Assistant. The 2025 SReXperts conference provided key updates on these developments and more.

Each year, Cisco Live brings together tens of thousands of networking professionals for a week of announcements, deep-dive sessions, and the kind of candid conversations that only happen in person. This year in Las Vegas, WWT sent a team of networking subject matter experts covering wireless, switching, SD-WAN, core routing, optical networking, and data center networking. What they brought back was a consistent signal: AI is no longer a strategy conversation, it is an infrastructure conversation, and the network is squarely at the center of it.

WWT engineering resources share what stood out to them at the flagship technology conference.

The optical landscape can be a rapid changing environment, and keeping pace can be an intimidating journey. Let us unwind this evolving puzzle for you.

Optical networking is shifting fast in 2026. Get up to speed on 800G/1.6T, CPO, open line systems and what it means for your infrastructure.

Members of WWT's Core Networking Team share their key takeaways and insights from the Optical Fiber Communications Conference 2026.

Coherent pluggable optics are revolutionizing networks by merging optical and IP layers, boosting capacity and efficiency while lowering costs. Interoperable modules, open line systems and high-power optics are key drivers. This shift enables significant savings and scalability for network operators, with the industry moving toward 800G and ultra-long-haul solutions. This technology is a major advancement in networking.

From new levels of visibility to AI integration to breakthroughs in optical networking, our experts share what stood out to them at the flagship technology conference.

The release of 100G ZR coherent QSFP28 transceivers from Nokia, Cisco and others promises to accelerate the already rapid shift from traditional core network designs to optical and packet converged architectures.

This year's SReXperts conference showcased Nokia's focus on enabling AI solutions and enriching their solution portfolio.
