The standard installation will provide the black armored cable directly from the FDP white box on the telephone pole to your fibre modem. The last time I chose to route it from the ceiling down to the room where my modem is installed, they charged me RM100 just to climb up the rood pull up my roof tiles and pull the cable through the ceiling tied with a stick. That also they didn't provide any FWS box which costs less than RM10 with coupler for me.

If you want to prepare for the standard installation, just buy the FWS box find a nice one, usually a SC-SC PC-type(blue)/APC(green for some TIME installations) coupler and your desired patch cord cable to hook up your modem with the FWS box. You can get them all including delivery for less than RM20.

A 2-5M length patch cord(yellow with blue connector head) with fusion spliced SC-SC PC connector is more than enough since the FWS is usually placed nearby fibre modem(ONT).

Lookup the items I posted with the initial post of this thread.

Get a sturdy looking one with at least 2-4 ports depending on your future needs.
2 ports FWS should be fine for most homes. The better ones comes with compartment that allows you to rewind excess fibre cable for tidy setup behind.

Before you jump straight into the order make sure the coupler used by the TM Unifi installers at your area is using for PC or APC type connectors.

The common one should be PC type but just to be safe. APC type is slightly more expensive.

Your patch cord must follow the suitable type as well.

Mostly Unifi is using PC-type connector. But don't worry the 2 items under RM10 only right?

That amount can't even get you 2 cups of Starbucks while a proper FWS will get you a nice setup for years to come.

If you still feel wasted, ask for refund from the shop you ordered from saying it was wrongly ordered and did not fit the installation at your place.

Anyway you can also ask your neighbor who installed Unifi line, ask them if the connector is blue/green. If possible take a picture and send to the seller.

So do we need the FTB still? Or from the pole connects to FWS directly via drill hole or ceiling?

The FTB not really needed since we don't really have a wholesale passive fibre infra provider like in other countries.

For the FWS, in my opinion is more important to isolate and allow DIY repairs in future just in case the fibre cable is fracture inside your house and needs a patch cord replacement.

Usually the standard installation already provide the cable with a connector to be plugged directly into your modem. But my suggestion is go a little extra by asking the installer to plug it into the coupler and plug a patch cord to separate into 2 sections for easier future troubleshooting.

The coupler is to be inserted into the one of the slots in the FWS as a port.

Do check with your installer in advance which type of connector type they're using in your area before deciding to buy the correct coupler and patch cord.This is to avoid wasting your money.

My TM Huawei Echolife HG8240H uses the blue colored UPC connector like that. So should be correct.
Not sure about the other ONTs such as Nokia and FiberHome.

You might want to try using those long FWS similar to those in Japan which can fit only 1 coupler inside.
