Re: Outside plant - prewire customer demarc preference

That’s exactly what I did. I was able to get a 3/4 conduit from my furnace room/network closet to the exterior of my 
home where utilities enter. It took some doing but I got it in, terminated in a NEMA box.

When we got fiber a few years ago, the installer told me it was the easiest install he’s ever done.

In that conduit I have fiber, coax, one Cat6 and also a sprinkler wire (whomever built my home had sprinklers put in 
the back yard but not the front, but I took care of that oversight).

If I was building a house I'd just get some 1" conduit from the outside to the inside.  Put it in a NEMA box.  That 
solves the problem forever.

As a fiber ISP, and assuming you're doing your own WiFi in the house, you can do conduit inside or we can just run 
the fiber.  We don't want to run up/down walls and such.  99% of our installs are through the exterior wall and then 
a u6x covers the house.  We run fiber 

If you're in a cableCo area just run coax to get to your modem/router situation.

I'm not sure what the Cat5 is for outside.  Ethernet isn't going to work and DSL is nearly dead already.

Thanks Brandon Martin,

I agree 1-inch smurf tube is overkill for FTTH. From my quick research 
into all things FTTH, which I didn't know anything a week ago :-) ...

The regulators in other countries still believe they will create 
competition.  The 25mm/32mm access duct (I'm going to make up a new 
term, and just call it "access duct", i.e. that smurf tube, conduit, 
pathway thing) is big enough for either a fiber microduct, cat 6 copper 
or RG6 coax.  Even a 12/24/48-volt DC power cable for active 
equipment at the NID/demarc.  The regulators keep all their competitors 
happy by not favoring any particular technology.

In practice, the countries with the biggest FTTH deployments have very 
little FTTH competition at the physical access layer.

Microduct, microduct, microduct is what the dominant access provider 
wants in those countries.  The dominant carrier wants builders to install 
"direct fiber" or "bypass fiber" microducts in new construction directly 
from every dwelling (house or apartment) to the carrier's central access 
point for the builder's development (apartment buildings or neighborhood).

Microduct only means no pre-built access for other competitors.

Apartment construction in Asia is very large. Several countries are 
also adding in-building mobile/wireless service requirements for new MDU 
building construction.


My interpretation, not understanding the country-specific FTTH fights...

The regulators appear to say, Ok, dominant carrier - you can have 
"direct fiber" microduct but builders must also provide an "open 
competition" 25mm/32mm access duct from the building entrance point (NID) 
or apartment consolidation points (CP) to the individual distribution box 
(DD) inside each dwelling.

Just my uninformed take, corrections welcome.
