Verizon offered analog channels? How? True analog isn't possible over fiber AFAIK, so what does this mean, exactly?

Is a fiber strand analog or digital? The answer is no, it is just a transport medium. No equipment manufacturer in their right mind would create a device that uses analog directly over fiber so it is all packaged in a digital transport and split by the equipment (NIU) installed at your house.

I think they're just removing a service that few people knew about, or used, anyway.

Fiber is capable of supporting both analog and digital transmission, just like electromagnetic signals down a copper line.

Verizon FiOS sends three independent signals down the same fiber line, using three wavelengths (colors.) One for QAM download which is an analog/digital hybrid just like cable QAM. The second for IP uploads, and the third for IP downloads. The IP upload/download signals are fully digital.
