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

|---|---|
| Scope | 800GBASE-DR8 defines this eight-lane, 16-fiber single-mode application. OS2 headroom alone does not make a later 1.6T or 3.2T application a transceiver-only upgrade; each one needs its own lane map, polarity and loss check on the installed plant (Chapter 8.10). |
