What? How'd that be possible?
- antirez 9y agoLight can travel in air much faster it can travel in glass.
- yusyusyus 9y agoSimilarly, copper is faster than glass too (but not faster than air). The trade folks refer to copper in terms of "velocity factor". Example, some arbitrary RG-6 I'm looking at has a velocity factor of 81%. Equivalent refractive index is 1/.81 for ~ 1.23.
- fridek 9y agoRefraction index of light in fiber is ~1.44. Rule of thumb for packets in transit is 200km/ms.
