Today Jeff cut a segment out of it, and peeled away the layers to see what is in it.
The marking on the outside said "Victrack by Corning" and also "12/24". And it's rodent resistant. The system we develop at work involves drawing maps of where cables and other equipment are installed. We don't draw the maps, that's a network designer's job - we write the software that lets them do it. So, we are able to test our software by making up new cable, and new types of cable, but this is the Real Thing.
Here's Jeff peeling away the layers. The black layers are very tough. Cable gets a lot of protection. There's also a tough woven layer.
And here, Jeff has managed to peel the very fine red sheath off one of the actual optical fibres. You can hardly see it, but it's the one with the half-length sheath.
We're taking this wonderful bounty to work tomorrow.
