      Sure, but the glass core is only 8–9 µm wide, it’s a minuscule amount of glass compared to copper cables so it’s not really worth it to melt it down.

        Most optical fiber is 125um of glass with 250um coating. The coating and the jacketing that make up the cable (mostly non-recyclable plastic) are the real problem.

        But it’s still dirt fucking cheap to produce.

        The expensive parts of fibre are the transmitters/receivers at each end and the labour to splice/terminate it properly.
