You got it.

The last slate binder is left out.

Hence why larger F1 cables come in multiples of 600.

At least now a days it's a plastic binder wrap... used to be string, and after a few years in the hole with a gel filling... things can get tricky.

28 guage cable would be gnarly to splice, especially using B connectors, which is all I can imagine you guys would use for high density splicing back then, wow.

You've definetely got my appreciation -- that's a talent! I couldn't begin to learn to work with such conditions. I complain about 24 guage

It was an experiment GTE was doing to save duct space in manholes. This was over 30 years ago, so no filled cables then. They used a special amp connector made for the small gauge. Don't know how it all worked out, I got a job with the Bell System shortly after that. Of course we splice larger pulp cables. What amazes me is one glass can carry more information then the largest cable I ever spliced.
Feeling pretty old here.

Well...

Any type of modulated frequency carrying cable has a much larger capacity than a copper loop ever will. The problem is there are many more pieces of active electronics with RF/optical.

Copper loops are much more economical.

Cable telephony for instance is going to be interesting. We're going to be placing active VOIP boxes fairly soon. In some systems, they have taps that have access doors with 110 blocks in them, and that part takes care of dialtone off of the cable system.

Very interesting stuff.

Fiber is a great thing, it just sucks to splice. Some of the larger trunk fiber we use to feed remote headends is 144 strands plus. Takes over a day to splice the whole thing.

Give me a 25 pair 710 press any day.
