While cleaning out our back yard shed, I came across a coil of cable of a kind that I have never seen before (image below). It was left here by the previous home owner, who worked in some kind of technical field.
It has some unusual features. Other than the fact that it has two pairs (blue, blue/white, orange, orange/white), the pairs are not twisted, and it's wrapped in a shield that is much more rigid than foil, more like thin copper (also below).
There are also what look like three streamers or tracers, two red and one blue, plus a string. The jacket is very thick, suggesting it's an underground cable. And one more thing: it's filled with some kind of grease, maybe silicone?
The jacket has some markings. One is "WE-B 2 PAIR." I did a search for that and couldn't come up with anything. Other markings are numbers, printed in vertical every two feet along the cable: 422238, 422240, 422242, etc., which obviously refers to a length measurement.
