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.
