Jay put together an initial copper cable run list. It's 39 cables at the router sites, each of varying length. Network-wide, we're somewhere around 600 patches. Terminating ethernet cables on site can be a real pain. At that scale, it can take a significant chunk of the day. So, we're going to estimate the lengths ahead of time and get them pre-made. We'll send some additional cable along in case our lengths are off, but this seems the best way to avoid unhappy engineers who haven't made cables in years. Happy engineers are productive engineers.
