Alec from Technology Connections covered the topic of consumer optical standards - or rather, the lack thereof - in a video that's now 4 years old: https://youtube.com/watch?v=CwZdur1Pi3M https://youtube.com/watch?v=CwZdur1Pi3M It mostly boils down to the reason others already mentioned: fragility, cost (optical transceivers have only recently become cheap enough to enable the use case of optical cables that behave like copper ones) and the requirement for copper wires anyway in order to carry power in addition to data.
