Highlights

  • Cisco's October networking update spans production systems, customer shipments and new switching silicon targeting connections within and between data centres.
  • A planned optical module collaboration with NVIDIA aims to increase bandwidth density while retaining the serviceability of pluggable network components.
  • Annual revenue increased 12% YoY to USD 63.3bn in FY26, supported by a higher fourth-quarter contribution across the technology business.
  • Management's FY27 revenue forecast anticipates further growth, while G302 shipments and optical specifications retain their individual product development schedules.

Several stages of AI network development are progressing at Cisco Systems (NASDAQ:CSCO), the networking and security technology provider. Its October announcements cover deployed Silicon One systems, further chip shipments and plans for a denser optical module. After the market session ended on 26 October 2026, Cisco shares closed at USD 110.24, up 3.51%. The technology milestones follow annual revenue growth and management's higher FY27 outlook, bringing both near-term product delivery and longer-term optical development into the operating agenda.

Silicon Portfolio Addresses Different Data-Centre Connections

At the 12 October Open Compute Project summit, Cisco reported that leading hyperscale operators had deployed systems powered by Silicon One P200 in production. Those systems address connections between locations, including the latency and congestion requirements associated with coordinated AI workloads.

The company also reported shipment of its first G300-powered systems to customers. The underlying G300 silicon was available for sampling, marking a different stage from P200 production deployments.

A further addition, G302, provides 51.2T switching capacity and is designed for top-of-rack systems connecting servers with the wider data-centre network. Cisco plans to begin G302 shipments before the end of 2026.

The product portfolio therefore covers multiple network roles. The disclosed status of each product remains specific: production use for P200 systems, customer shipments and samples for G300, and a future shipment target for G302.

Optical Module Plans Target Greater Connection Density

Cisco and NVIDIA announced plans for Ultra-Dense Small Form Factor Pluggable optical modules, known as USFP. The proposed design supports 400Gb/s-per-lane signalling, with initial planned transceivers using sixteen full-duplex lanes.

The footprint is intended to be comparable to existing octal small form-factor modules, with capacity of up to 12.8Tb/s. Design comparisons indicate four times the bandwidth density and approximately 1.3 times the power efficiency of 200Gb/s-per-lane optics.

These specifications describe the intended technology. They do not establish that a full commercial deployment has already occurred. Work with connector and module suppliers is intended to provide multiple hardware sources as the ecosystem develops.

The companies also plan an open specification through a community-led project. The approach seeks to combine greater bandwidth with the deployment flexibility and servicing practices associated with pluggable optical modules.

Completed Earnings and Annual Forecast Provide Financial Context

Cisco generated USD 17.3bn of revenue in 4QFY26, ended 25 July, increasing 18% YoY. GAAP net income reached USD 3.9bn and diluted earnings were USD 0.97 per share. Operating cash flow was USD 5.4bn.

Full-year revenue increased 12% YoY to USD 63.3bn. Management forecasts FY27 revenue of USD 72.2bn–73.4bn and non-GAAP earnings of USD 5.05–5.11 per share. Its first-quarter revenue outlook is USD 18.0bn–18.2bn.

The guidance covers Cisco's wider business rather than a separately quantified contribution from the new optical programme. Product delivery has its own milestones, including the planned year-end G302 shipments and development of the open optical specification. Financial execution and technology availability will consequently provide separate updates on progress across the company's networking agenda.
