800GBASE-DR8 link over MPO-16/OS2: eight parallel single-mode lanes using 16 fibers; later application reuse requires a qualified migration map

| Value kind | observed — Reported measurements, counts, and specifications keep the precision and scope stated by their source; an exact specification is not treated as a range. |
|---|---|
| Scope | 800GBASE-DR8 establishes this eight-lane, 16-fiber application. OS2 attenuation and dispersion headroom alone does not guarantee 1.6T or later reuse. Verify lane and wavelength map, duplex or parallel fiber count, connector and polarity, channel loss and reflectance, reach, module, and host requirements for every application. |
