AVGO (Broadcom) Earnings + Signals for Networking (Free Article)

Summary
Broadcom's Q3 earnings validate that AI networking demand is surging, arguing that copper, pluggable optics, NPO, and CPO will scale simultaneously rather than cannibalize each other. The company's massive FY28 AI revenue guidance and aggressive factory expansions confirm severe, ongoing shortages in laser supply while presenting a compelling long-term valuation setup for the stock.
  • Broadcom generated $16.7B in AI semiconductor revenue in Q3 (up 221% YoY), with implied networking revenue at roughly $4.5B.
  • The company guided AI semiconductor revenue to reach ~$115B in FY27 and ~$230B in FY28, with supply already secured against these forecasts.
  • 100G and 200G electrical lanes are ramping together, indicating 800G transceivers will continue to grow alongside the early ramp of 1.6T transceivers.
  • Broadcom is more than tripling its EML, CW, VCSEL, and indium phosphide factory capacity YoY to address demand that is far surpassing supply.
  • Ethernet is moving deeper into the scale-up network via Broadcom's Tomahawk Ultra switch, challenging NVLink's historical dominance in that domain.
  • Copper connections are being stretched to survive into the 200G per lane generation, with 200G per lane AECs reaching up to 6 meters.

Broadcom's FY28 AI revenue target of $230B implies roughly $30 of FY28 EPS, making the stock look highly attractive at around 12x FY28 earnings if they execute against their secured supply forecasts.

The author notes AAOI benefits from both the 800G/1.6T transceiver overlap and the severe laser shortage because they fabricate a significant amount of their own InP lasers.
The author notes AAOI benefits from both the 800G/1.6T transceiver overlap and the severe laser shortage because they fabricate a significant amount of their own InP lasers. Risk: Broadcom and other competitors are aggressively tripling capacity, which could eventually alleviate shortage pricing and compress margins when new supply comes online.

Broadcom's commentary that EML and CW laser demand is 'far surpassing supply' provides strong validation for LITE's tight supply environment and pricing power.
Broadcom's commentary that EML and CW laser demand is 'far surpassing supply' provides strong validation for LITE's tight supply environment and pricing power. Risk: Industry-wide capacity expansions will eventually qualify and come online, meaning today's shortage pricing will not last forever.

SMTC benefits from the entire coexistence roadmap, having optical exposure through drivers/TIAs/HieFo, as well as massive copper exposure which Broadcom confirmed will continue to scale.
SMTC benefits from the entire coexistence roadmap, having optical exposure through drivers/TIAs/HieFo, as well as massive copper exposure which Broadcom confirmed will continue to scale. Risk: Copper's viability at higher speeds remains physically constrained by distance, eventually forcing a harder transition to optics for larger scale-up clusters.

Broadcom's investments in stretching copper signals via AECs and retimers confirms that copper will survive into the 200G per lane generation, directly validating CRDO's copper exposure.
Broadcom's investments in stretching copper signals via AECs and retimers confirms that copper will survive into the 200G per lane generation, directly validating CRDO's copper exposure. Risk: The transition to NPO/CPO for longer rack distances could cap the total addressable market for copper-based AECs over time.

The author explicitly calls out VECO as an upstream beneficiary selling equipment into the massive industry-wide factory capacity ramp for EML, CW, and VCSEL lasers.
The author explicitly calls out VECO as an upstream beneficiary selling equipment into the massive industry-wide factory capacity ramp for EML, CW, and VCSEL lasers. Risk: Capital expenditure cycles in semiconductor equipment can be highly cyclical and dependent on sustained downstream hyperscaler demand.

Broadcom's Tomahawk Ultra Ethernet switch is seeing stronger-than-expected uptake in the scale-up network, allowing hyperscalers to build custom accelerators around Ethernet rather than proprietary fabrics like NVLink. Risk: NVIDIA's ecosystem remains deeply entrenched, and Ethernet's latency/bandwidth capabilities may still lag NVLink for the most demanding frontier model training clusters.
