[Q&A Highlights]
Question 1: Did the linearity of cloud orders accelerate through the quarter, and how do you view visibility beyond FY25?
Answer: Strong order flows continued and accelerated in Q2, with service providers showing steady increases and cloud demand experiencing a step function growth. The momentum is expected to continue into Q3, with visibility suggesting sustainable long-term demand.

Question 2: How do you address concerns about gross margin impacts from the ramping of pluggables and new products?

Question 3: Can you provide more details on the top customers' contributions and the sustainability of cloud revenue growth?
Answer: The largest customer contributed 13.4% of revenue, and the second largest (AT&T) contributed 10.4%. The top five customers made up 45% of revenue. The broadening application base and increasing number of cloud providers suggest sustainable and durable growth.

Question 4: What is the outlook for the pluggable optics market, and how significant is the opportunity?
Answer: The pluggable optics market is substantial, with significant opportunities in regional GPU clusters and other applications. The market is expected to grow, with Ciena well-positioned to capture a significant share.

Question 5: How is Blue Planet performing, and what are the long-term opportunities?
Answer: Blue Planet achieved record quarterly revenue, driven by digital transformation projects and AGENTIC AI integration. The platform is well-positioned to support service providers' AI-driven operations.

Question 6: What is the status of the routing and switching business, and how is installation capacity being managed?
Answer: The routing and switching business is gaining momentum with new customer wins and increased orders. Installation capacity is being ramped up to meet the growing demand, with a focus on both service providers and cloud customers.

Question 7: How are tariffs impacting the business, and what mitigation strategies are in place?
Answer: The current tariff regime is expected to result in a $10 million quarterly cost, with mitigation strategies in place to minimize the impact. The net effect on the bottom line is expected to be immaterial.

Question 8: What is the outlook for gross margins, and how will product mix affect profitability?
Answer: Gross margins are expected to improve over time, with the mix of products and cost efficiencies playing a significant role. The company remains confident in achieving mid-forties gross margins and mid-teens operating margins by 2027.
