Why are BT using Jonny Rotten to test fttc 
Thx for this, watching now

This video should be sent to the area manager of open reach in my town

Found this - it may interest some people https://www.ispreview.co.uk/index.php/2021/06/video-virtual-tour-of-fttp-broadband-with-bt-and-openreach.html

Anyone else notice in a few parts he references showing us the OLT but it appears to have been cut from the video

Best video I have seen yet of showing the various parts of the network though.

While these infrastructure videos are interesting, it always bothers me how they completely gloss over how two fibres suddenly become a single fibre later on.

I'm not sure what you mean there, Alex? At what point in the chain is this problematic?

[burakkucat]

I am (somewhat) amazed by the low standard of literacy within the BT Group plc, as a whole.

The first example is right there on the "cover page" of the video, "BT Holesale" (sic). 

Then there is the perpetual failure to understand the difference in meaning of the English words "premise" and "premises".

I'm not sure what you mean there, Alex? At what point in the chain is this problematic?

The fact that at the start of the video he is plugging in two fibres but once you reach the pole you suddenly have one fibre.  Where does this change and how?

Another example, "I'm not gonna bore you much with the details but this is called a WDM" so we end up not knowing WTF it actually does.

I mean sure, I just googled WDM and its exactly what I would expect it to have been, but why gloss over it?  Why not just mention that this allows aggregating multiple fibre signals down a single fibre by converting them into different wavelengths?

Also, how does that help?  What part of the network is it on?  If its not currently used, why even bother installing it now?  If it is currently used, where is the inverse function performed?

[niemand]

Not sure I get the issue. Seems to have described it just fine as a filter that mixes and unmixes connections.

It's not changing the wavelengths of anything. It's combining on the one side and splitting on the other, filtering via optical bandpass to reject unwanted wavelengths.

Be mindful of time constraints and the intended audience.

Perhaps describing it as a passive MUX / DEMUX for optical signals would assist in understanding its function.

It seems to be a rule that people who right marketing-speak can’t right english to save there lives.

So would that be what combines GPON and XGPON, as they already operate on different wavelengths?  Or is that done further down the line?  Its the fact I cannot grasp where in the network this sits that doesn't help.  Is this to combine fibres internally in the building or externally?

I'm still trying to wrap my head around why you would have seperate fibres for different services if it can be combined down the same fibre?  I get that generally cost is a factor, that fibre that handles multiple wavelengths is more expensive, but where does this all fit in?
