Bottom line
The sleeper story is hyperscalers creating a parallel fiber ecosystem that's breaking VIAV's 30-year dependence on telco spending cycles, with field instruments now 25-33% non-telco versus historically 10%. The Street sees 'AI data center strength' but misses that this is architectural disruption, not cyclical recovery. The binding constraint isn't demand but working capital to fund 25% growth, hence why DSO metrics conveniently disappeared this quarter. Oleg: 'When I see the money, I'll believe it' about telco spending reveals he's betting on hyperscalers, not carriers. My view changes if Q2 Spirent revenue comes in below $50M, signaling integration issues or market weakness.

The 30-second version

  • Field instruments quietly becoming the sleeper growth story as hyperscalers bypass traditional telcos
  • Data center ecosystem revenue approaching parity with telco for first time ever
  • Management stopped disclosing DSO and working capital metrics while cash jumped $120M
