In Part 2 of this photo story we go inside the home to check if it is all working

Computerworld editor Sarah Putt has documented the installation of a Chorus Fibre To the Home connection in Albany, Auckland that took place earlier this month. In Part I, we showed how the black cable, which runs from from the External Termination Point outside the house to the roadside cabinet, is joined to the blue cable located in the roadside cabinet, via a Fibre Access Terminal.
In Part II, we head indoors from the External Termination Point...
Step 9
The ETP on the outside wall of the house. This connects the black fibre cable to the newly installed Hybrid Composite Cable (HCC). The HCC runs internally from the ETP to the Optical Network Terminal (ONT) inside the house.
Step 10
Inside the garage, the home distribution panel is a good example of the Telecommunication Carrier Forum Structure Cabling or ‘star wiring’.
Step 11
Once the fibre cables are connected, another installer goes to the street cabinet to connect the passive splitter
tail end connector into the cabinet’s optical fibre distribution frame.
Step 12
The fibre is cleaned using a Microcloth cleaner.
Step 13
The PON Power test. An in-line power meter provides a reading of light power output between the P-OLT (located at the exchange, the P-OLT contains the lasers) and the house.
Step 14
A Fibre Inspection Probe Test at the ONT is carried out to ensure the fibre is clean. A magnifying wand is attached to the connector head magnifying the fibre end to 400x its original size. If it fails the test, the fibre is cleaned using a dry Microcloth.
In the final part of this installation series tomorrow, we'll see how the customer connects up to the residential UFB service in their area, as well as alternate method of connecting fibre at street level.

UPS
A UPS is available as part of the install, and is listed on the Chorus price sheet. It's up to the end user to specify one if they want it.

ONT description
It is not clear how the ONT is powered? Also if the power to the ONT is lost what happens in the case of Emergency?

If the power goes, so does the DECT phone. Mobile is the best bet for teh emergency call.

ONT description
The ONT is mains powered and if it loses mains it ceases functioning. It is up to the service provider or end user to provide a power protection mechanism for it such as a UPS. These days most people would have a mobile phone handy and would just use that for an emergency call. They are free on most mobiles I believe.
