It's been a while I looked into the whole FTTR solution and it's pros and cons.
(I didn't see the point for my place since I've already laid out CAT-5e during renovation previously).
Anyway, for anyone wanting a more technical explanation, I went down the rabbit hole trying to understand the FTTR stack and why someone will be stuck with this solution once you commit to it.
Basically the issue comes down to the use of the
single flexible fiber for connecting the main unit to the end points. The single fiber requires the use of bi-directional optical signalling over the one fiber.
Currently the most common network equipment that operate with multiple optical signals (wavelengths) over the same fiber is
GPON technology, so the FTTR equipment basically extending GPON to the room.
There are bi-directional (dual-wavelength) SFPs
available for Ethernet switches/routers, but I don't believe that they will work over the fibers used in FTTR.
There is also an alternate Polymer Optical Fiber (POF)
technology but that uses a different type of fiber than what is used for FTTR AFAIK and is not (yet) bidirectional. In addition, I have not even heard anyone talk about POF for home networking around here.
One more concern is the fragility as it was made to look 'nice & invisible'.
Again, the infra laid can be reused with some customisation.
