NewPhotonics has added a laser-integrated option to its near-package optics (NPO) silicon photonics lineup with the NPC50506 6.4T DR32 optical engine chipset. The company is targeting serviceable, socketed near-packaged optics built to the Open CPX MSA form factor, pushing optical conversion closer to a switch ASIC or XPU while keeping the optical engine independently testable and field replaceable.
The NPC50506 is described as a compact 6.4T optical engine with an integrated laser, intended to avoid designs that rely on an external light source. NewPhotonics attributes the integrated laser approach to lower optical insertion loss and reduced power consumption. The design uses a low-profile flip-chip BGA package, and the company says it eliminates separate assembly steps for laser attach and optical coupling.
For link electronics, NewPhotonics lists integrated 224 Gbps PAM4 modulation and control circuitry. Other stated features include per-channel output power monitoring, transmission-disable access, and a serviceable socketed architecture aligned with the Open CPX-MSA ecosystem. NewPhotonics also notes it recently became a member of the Open CPX MSA.
Serviceability is the practical engineering angle here. Socketed NPO is aimed at pulling optics closer to the electrical source to cut trace reach, but without the “replace the whole package” penalty associated with tightly integrated approaches. Independent testability before installation, plus field replacement of the engine, can matter as much as raw bandwidth density once these parts land in large AI clusters where maintenance windows and sparing strategy become first-order design constraints.
Doron Tal, SVP and GM at NewPhotonics, said, “We’ve taken a system approach to the chipset design to deliver important advantages in NPO manufacturing yield and service at AI-cluster scale.”
Commercially, NewPhotonics expects NPC50506 to sample in Q3 2026, with an HDK reference design planned for Q4 2026.
