The speed of light through a vacuum is a constant, but for example through fiber optics (ie, glass) it is only around 2/3rds that speed. Do you have any references to fiber cabling having a lifespan of "vastly longer than a century"? Most cable manufacturers give a stated lifetime of somewhere in the 20-40 years, with a general industry expectation that it will normally last more than that - but I've never heard anyone claiming "vastly longer than a century" before now...
