Switch chips with optical ports

Co-Packaged Optics (CPOs)

From Jensen Huang showcasing CPO switches at GTC 2025 to a wide range of vendors demonstrating optical engines integrated inside ASIC packages at OFC 2025, co-packaged optics

CPO Switch: Next-Generation Integrated Optical Networking

CPO switches shorten the electrical signal path, reduce power consumption, and decrease the number of pluggable modules by co-packaging optical modules with switch chips, while improving link reliability.

Co-Packaged Optics in Modern Data Centres

In a co-packaged design, the laser diodes, modulators and detectors are integrated on or beside the switch chip (often on a silicon photonics engine) so that the high-speed SerDes signals

NVIDIA Reveals 1.6Tbps Silicon Photonics CPO Switch

Six optical components, each of which contains 3 1.6T silicon photonic engines, totaling 18, are placed around the switching chips. Each optical engine has 2 external laser input ports (one

CPO Switch: Next-Generation Integrated Optical

CPO switches shorten the electrical signal path, reduce power consumption, and decrease the number of pluggable modules by co-packaging optical modules with

Co-Packaged Optics — a deep dive | APNIC Blog

There are two main ways to integrate these optical engines inside the ASIC package containing the switch or XPU cores.

Nvidia Unveils Game-Changing Optical Network Switch

In data centers today, network switches in a rack of computers consist of specialized chips electrically linked to optical transceivers that plug into the system.

Broadcom Upgrades Co-Packaged Optics Switch to 51.2 Tb/s

But the new switch uses silicon photonics to create optical interfaces in chiplet form. The chiplets are then directly attached to the switch ASIC in a package, providing major power and...

25.6 Tb/s Multilayer Switch with Co-packaged Optics BCM56999

Co-packaging with optics eliminates the need for pluggable optical transceivers, lowering the overall power consumption of the switch box, reducing the congestion at the front panel, and enabling
