Note, both are right, depending on the starting point and goals.

Historically teclos have installed (relatively) low count fiber
cables, based on a fiber to the pedistal and copper to the prem
strategy.  If you have one of these existing deployments, the cost
of home run fiber (basically starting the fiber build from scratch,
since the count is so low) is more expensive, and much greater cost
than deploying GPON or similar over the existing plant.

However, that GPON equipment will have a lifespan of 7-20 years.

In a greenfield scenario where there is no fiber in the ground the
cost is in digging the trench.  The fiber going into it is only ~5%
of the cost, and going from a 64 count fiber to a 864 count fiber
only moves that to 7-8%.  The fiber has a life of 40-80 years, and
thus adding high count is cheaper than doing low count with GPON.

Existing builds are optimizing to avoid sending out the backhoe and
directional boring machine.  New builds, or extreme forward thinking
builds are trying to send them out once and never again.
