In TBD, it’s not a “release” until its production ready. The methodology and philosophy doesn’t prevent you from developing multiple feature branches at once or even deploying a work in progress feature branch to a dev environment.
All TBD requires in that case is once the feature branch is production ready, it’s merged to the trunk. You may need to add a feature toggle if there are multiple release like for different architectures. And you also might benefit from using git tags and deploying to production from a git tag instead of the most recent commit on a branch.
Exactly what you need to do is going to depend on the project’s exact needs but TBD is totally possible in that example.
Its not new tech but you’d most likely only see this in a datacenter or buildings with 10 Gb connections as this is fiber optic cabling. One would need an SFP to actually connect it to the port however. Also the tips of the fiber were probably scratched when installing it into the vent holes so the whole cable will probably be replaced and then fixed, so there are multiple failures here.
This is what an SFP looks like.
