- dfox 7y agoThe idea that free space optics are somehow secure against eavesdropping seems to parallel 80's idea that you cannot practically tap into optical fiber. You still should encrypt the link if you at all care about its security.
- fulafel 7y agoBut what makes it work better outside fiber? LEDs by themselves are agnostic about the medium afaik. Maybe it's higher tx power in the noisier environment?
- swiley 7y agoCan’t fiber optic transmitters blind you?
- _trampeltier 7y agoSinglemode fiber does use a laser, not just a "normal" light source.
- thombat 7y ago>> Radio frequencies are also susceptible to hackers who can intercept signals, Islim notes, whereas visible light could be protected by opaque objects. So the security hinges upon it being easier to block visible light than more conventional radio signals. Seems that a fibre optic is still more secure and likely to achieve greater range for the same transmission power.
