Coherent launches PhotonLink integrated optics platform for AI datacenters

Marvell Technology shares gained 4% Monday after the chipmaker detailed a set of 2-nanometer optical connectivity demonstrations aimed at AI data centers. The company plans to present the technology during ECOC 2026, a major European optical communications conference, with demonstrations covering several configurations designed for higher-speed links inside and between data center facilities. Marvell will show 400G-per-lane optical PAM4 using its 2nm process, along with an 800G ZR/ZR+ pluggable solution that includes MACsec security. The portfolio also includes demonstrations of 1.6T ZR and O-band coherent-lite technology, which Marvell said are intended to support the increasing bandwidth requirements of AI infrastructure. The technologies will be displayed at the event in Malaga, Spain, which runs through Sept. 24.

Marvell Technology unveiled three 2-nanometer optical technologies aimed at easing one of AI infrastructure's biggest pressure points: moving more data through increasingly crowded networks. The lineup stretches from 400-gigabit-per-second-per-lane PAM4 technology built for 3.2-terabit connectivity to an 800-gigabit ZR/ZR+ pluggable with integrated MACsec encryption and 1.6-terabit coherent links spanning data-center connections. Marvell is also showing a 102.4-terabit-per-second co-packaged-optics platform among 38 demonstrations at ECOC. Shares climbed approximately 3.4% to $252.39 Monday, a level 109.07% above the $120.72 GF Value. The company's latest quarter produced $2.739 billion of revenue, up 37%, while data-center sales jumped 46%, though the next test is execution through customer design wins, production schedules, shipment volumes and margins.

Qualcomm shares jumped approximately 7% to $190.085 after the chip designer disclosed an AI-infrastructure partnership with Amazon that could see the e-commerce and cloud giant purchase as much as $60 billion of Qualcomm products. Under the arrangement, Amazon would receive purchase-linked warrants valued at roughly $4 billion, equivalent to about 6.7% of the potential $60 billion purchasing ceiling. The two companies are also building custom inference silicon and optical connectivity capable of reaching 1.6 terabits per second. The deal gives Qualcomm a credible path to becoming a larger supplier inside hyperscale AI infrastructure rather than remaining overwhelmingly tied to mobile chips. At $190.085, Qualcomm trades 8.3% above its $175.52 GF Value estimate, suggesting the market is already pricing in part of the Amazon opportunity.
