While I was returning to my parents' house, I made reservations for the construction of my parent's cable TV.

Because the cable television company requested "they want to change to optical fiber" (construction fee was free).

So, I was able to observe the construction that pulled the cable from the overhead catenary line up close.

I asked young workers who came to the construction, to watch the whole construction process.

In particular, I was interested in the part that creates the interface of the optical fiber, so I have been watching their work, however, they used a handy type crimping device, and made interface part at the moment.

"Not to be helpful"

In the case of electricity, I can understand both analog and digital, however, I could not make a image of making the joining optical fiber.

Well, even so, the optical fiber was thin, like thickness of the hair.

I came to think that I would like to pull the optical fiber from the house to the public hall 700 meters away, and establish a neighborhood association server (or, I want to make it possible to use wireless LAN), however, they were stupid ideas from the view of construction and maintenance cost.

Before that, this is a breach of contract
