Is the fiber that was installed in the 80's useable now? I thought I had a technician tell me that all of the fiber installed back then was obsolete now because the technology had changed from back when they installed big bundles of multiple strands.
The number of strands really doesn't matter. Since the 1980s utilities have been dealing in single mode fiber. It is almost entirely different from our side of things which is multi mode. Single mode diameters have in fact changed (very) slightly over the years but we are talking 1.3 micron to 1.55.
