Near-Packaged Optics
Materials, devices, and modules on one structural map
In the OIF co-packaging framework, near-package optics has a specific meaning: a packaged ASIC and an engine, socketed to a common substrate so they can be attached and removed for assembly and rework. NPOTEC organizes three planned layers around that boundary: raw materials, devices, and modules.
The drawing below separates mounting positions only. It is not a photograph, and it is not a bill of materials shared by every design.

Raw materials
Silicon photonics and germanium detection, laser materials, substrates and sockets, fiber, and thermal-mechanical retention. Each is a place in the literature, not a stock line.

Devices
Modulation and detection, light sources, electrical interfaces, and fiber coupling. There are at least four electrical sketches and three source paths.

Modules
The socketed assembly, the optical engine, an optional external source, and the faceplate exit. On-board optics is marked separately so it is not folded into NPO.

How to read the classes
- 01
Start with mounting position. A front-panel pluggable, socketed near-package optics, and co-packaging on the same first-level substrate are three different drawings.
- 02
Then look at the options. The laser may be inside or outside the engine, and the framework sketches at least four electrical styles: retimed, linear, half-retimed, and direct drive.
- 03
Only then match materials. Columns on the materials page drop out depending on the first two choices. The page is not one purchase.
