Adtran Holdings
Adtran Holdings, the dual‑listed parent of legacy ADTRAN and former ADVA Optical Networking, completed its all‑stock business combination in July 2022, creating a vertically integrated optical networking and broadband access vendor. The company reported FY 2025 revenue of $1.084 billion, a 17.5% year‑over‑year increase, with non‑GAAP operating margin of 4.8% and diluted EPS of $0.23. A Domination and Profit‑and‑Loss Transfer Agreement leaves a contingent exit‑compensation liability of roughly $352 million, payable only if minority shareholders tender their shares. R&D intensity remains high at about 25% of revenue, supporting its three roughly equal revenue streams: Optical Networking, Access & Aggregation, and Subscriber Solutions.
Scale Across, Confirmed
Scale across is the emerging coherent‑optics interconnect that links AI data centers separated by tens to hundreds of kilometers, enabling workloads to spill beyond a single building. Ciena estimates more than 300 new AI‑focused data centers were commissioned in 2025...
Untangled
The data‑center interconnect (CPO) value chain is currently split into three headline layers: switch silicon from Nvidia and Broadcom, XPU‑side photonics from Marvell and MediaTek, and laser components from Lumentum, Coherent, Furukawa and Applied Optoelectronics. The article points out that...
Mycronic Anxiety with All So-Called Photonics Bottlenecks
Mycronic AB reported a record Q1 2026, posting net sales of SEK 2.5 bn (≈$235 m), up 17% YoY, and EBIT of SEK 938 m (≈$88 m) at a 37% margin. Order intake jumped 260% to SEK 2.53 bn, driven by AI‑adjacent demand across its photonics divisions. Management...
The Third Tier: Scale-Across Like Kriss Kross
NVIDIA introduced the "scale‑across" tier at Hot Chips 2025, defining a new networking layer that connects AI training clusters across buildings, campuses, and even continents. The approach relies on coherent optics and disaggregated WDM to treat distant racks as a...
