Ethernet payload one fiber pair carries in each direction when an OIF 800ZR line system fills all 32 of its 150 GHz C-band channels

| Value kind | derived — Derived values are guide calculations; their result is only as fixed as the stated inputs, scope, and method. |
|---|---|
| Scope | The 800ZR channel plan (single-span, 80-120 km amplified DWDM). Ethernet client rate, before any protocol overhead above Ethernet. ZR+ or performance modems and C+L line systems give different per-pair figures; use your line-system vendor's channel plan. |
| Caveat | A full-fill ceiling from the standard's channel plan, not a measured link; real systems may light fewer channels. |

| Derivation | 32 normative channels x 800GE client = 25.6 Tb/s per direction of a fiber pair |
