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: They list a variety of important ongoing applications for fiber optics.

Fiber Optic Fabrication: 

Developing a Green & Sustainable Fiber Optic Infrastructure with Air-Blown Fiber Technology:

Presentation slides for: TAG Infrastructure - (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.

Best wishes,
