That's one way to not be bothered about openreach poles in the area.

BT FTTP uses Infrared light, so you won't see it. How strong it is and what damage it might cause I don't know.

You can *see* the fibre optic signal once, though.

My understanding is the frequency is outside the visible spectrum so actually all that happens is you never see anything ever again in the eye you looked at it from.

*Please note, do not look directly into the beam of a fibre optic connection*

Just like love the sun ray lights through fibre optic 

Humans can only hear 20 Hz to 20 kHz range maximum.  We dont hear the actual data - analogue is converted to digital.
POTs uses 300 and 3,400 Hz for voice band. Modems do the clever stuff allocating the DSL higher frequency bins

>> sound coming from fibre optic cable or was it very silent?

It should be silent.
Fibre Optic: uses light rays at various wavelengths through thin glass fibres.

looks like someone has done the same as @johnson442

Of note is the SFP port on the back:


Has anyone else got one of these?

I do know you can hear the copper sound but I dunno if we ever will hears any sound coming from fibre optic cable or was it very silent?

wth is that.  I fear I lost 2 mins listening to it trying to figure out, expecting something related to Fibre Optic.
Is it supposed to be the 100bpm =  beats per min - eg drum beats.  Whatever, I found the loop rather irritating :/

This is the sound of the Openreach Fibre Optic on the pole  as I picked this sound pitch!
