Your question about sustainability of fiber optics is an interesting one.
I found little in the Rakow Library on the topic. I scanned a couple pages from Hecht's 2006 book Understanding Fiber Optics. He states "Fiber optics is here to stay."
I found a number of leads with an internet (Google) search:
For example, the The Fiber Optics in Sensory and Sustainability Applications (FOSSA) project: http://asl.ucsc.edu/fossa. They list a variety of important ongoing applications for fiber optics.
Fiber Optic Fabrication: http://www.appropedia.org/Optic_Fiber_Fabrication
Developing a Green & Sustainable Fiber Optic Infrastructure with Air-Blown Fiber Technology: http://www.fols.org/fols_library/presentations/Kurt_Templeman.pdf
Presentation slides for: TAG Infrastructure - http://www.slideshare.net/TAGThink/sustainability-the-all-fiber-future (includes a list of benefits of fiber optic networks & more)
Let me know if this is the right direction. If not, I will be happy to search further.
