Press Releases

Every GPU cluster is wired together by optics, and the schedule for standing one up is usually set by whether those optics arrive. PhoScale, which supplies 400G, 800G and 1.6T optical transceivers to AI infrastructure builders, system integrators and channel partners, will show its full product line at AI Infra Summit 2026 in Santa Clara.

The brand is new; the manufacturing behind it is not. PhoScale was launched to point the capability of an optical interconnect group founded in 2010 — its silicon photonics platform, its automated production lines, its test capacity — at a single market, and to put supply for that market on the ground in North America. Visitors will find the company in the summit's Start Up Zone for that reason.

The argument is a narrow one: in a market where lead times move more money than unit price, the supplier that controls both the photonics and the last mile into a US loading dock is the one worth talking to.

The group designs its own photonic integrated circuits and shares the platform across the entire PhoScale portfolio, rather than sourcing optical engines from third parties. Modules are assembled on a fully automated chip-on-board line running 300,000 units a month inside a 53,000 m² smart factory — with SMD placement accuracy of ≤1.5 μm @ 3σ, lens coupling repeatability of ±50 nm, and 99.99% gold wire bonding.

That vertical integration shows up in the specifications. PhoScale's 200G/lane series pairs in-house silicon photonics with 3 nm DSP platforms from Broadcom and Marvell, delivering 800G at 16 W and 1.6T at 25 W, with a low BER error floor of 1E-10 and receiver sensitivity of −5.5 dBm at pre-FEC BER 1E-6. The linear-drive (LPO) 800G variant removes DSP electrical shaping altogether for roughly 40% lower power.

The modules have been shipping for years. Optics from these lines have gone into production RoCE and InfiniBand fabrics at hyperscale — including a single spine-leaf build that consumed more than 110,000 modules across 800G and 400G. Interoperability is validated on live platforms, not just in datasheets: 24-hour PRBS-31 testing against NVIDIA Quantum QM9790 switches and ConnectX-7 NICs, plus CMIS 2.0–5.3 support and coding for Generic MSA, NVIDIA, Cisco, Arista and Juniper. Products carry ISO 9001:2015, CE, FCC, RoHS and FDA certification.

Manufacturing capability is only useful if the modules land on time. PhoScale holds North American inventory in its Ontario, California warehouse and ships DDP — clearing customs itself, so buyers deal with a domestic delivery rather than an import.

Every unit is tested individually before it ships, and every shipment includes the test report and a power-on video. Platform coding is done to order. Modules carry a lifetime warranty with advance replacement, so a failed link is resolved by a unit already in transit rather than an RMA queue.

PhoScale does not try to be a full-catalog optics distributor. The line-up is deliberately narrow — current-generation rates in the form factors AI clusters actually deploy — on the view that a focused portfolio is what makes real volume availability, honest lead times and locked capacity possible in the first place.

Three commitments follow from that:

PhoScale's team will be in the **Start Up Zone** for all three days, where the company is showing its newly launched North American operation alongside the full 400G/800G/1.6T line-up, datasheets and interoperability test data. Attendees building a cluster can request two free sample transceivers, coded to their switch or NIC platform, at phoscale.com/aiis2026.

PhoScale is the AI data center brand of an optical interconnect manufacturer founded in 2010, developing and producing high-speed optical transceivers for AI and high-performance computing networks. The group operates four global bases with more than 200 employees, a quarter of them in R&D, and supplies 400G, 800G and 1.6T optics to AI infrastructure operators, system integrators and channel partners across North America, Europe, Japan, Korea and Latin America. North American orders ship from PhoScale's California warehouse. Learn more at phoscale.com
