The framework says optical engines, like their pluggable counterparts, connect equipment over single-mode or multimode fiber. An engine can be pigtailed or built with a connector. The pigtail can be a high-density ribbon; if it is long enough, another connector to the front panel may be unnecessary.
That is an exit choice in the literature, not a connector design already settled by NPOTEC. NPOTEC lists fiber pigtails as one family in its planned full stack. The image is a conceptual product image.

Single-mode and multimode fiber, pigtail or connector
The framework says optical engines, like their pluggable counterparts, connect switches and servers over single-mode or multimode fiber. An engine can be pigtailed or built with a connector. The pigtail can be a high-density ribbon; if it is long enough, another connector to the front panel may be unnecessary.
What changes between designs An extra connector raises insertion loss relative to an equivalent front-panel pluggable. The document also says the high-density fiber connectors of the time, MPO among them, may not meet the size and density limits, and that a new connector technology may be required. That is a problem statement, not a connector design from NPOTEC.
After the optical conversion leaves the front-panel module, the fiber still has to leave the equipment. The framework discusses where fiber or copper exits the assembly, and how faceplate-connector loss spends the optical budget.
What changes between designs A pigtail that reaches the faceplate, or an engine-side connector that is patched onward, are different loss and density choices. The document does not appoint either one as the near-package exit part.
The framework splits the data fiber’s exit into a pigtail or a connector. If the external source is an ELSFP, continuous-wave light uses a blind-mate optical connection on a faceplate module to enter the system. The implementation agreement requires IEC 60825-2 Hazard Level 1 when the module is used as specified.
What changes between designs The continuous-wave inlet and the data-fiber outlet are two interfaces. The management white paper’s example says a 3.2 Tb/s optical engine has either 4 or 8 CW inputs, and an ELSFP has up to 16 CW outputs; the system vendor chooses the pairing. Those numbers are examples in that paper, not an NPO port quota.
