Tm cheap-out after broadband price cut few years back, hence no more FWS. 3 of my friends that got fiber installed after the period all don't get the socket...

Thanks for the help of clarifying earlier, since 3 years ago TM already stopped providing the FWS(wall socket) and outdoor demarcation box for landed homes to cut costs further but turned out to be a bad decision.Yet I don't know how they justified forcing their subscribers to sign a full 24months(2 years) pay remaining months contract when earlier subscribers only need to pay RM500 one-off early termination fee.
Remember the RM35 worth MCO handouts which claimed to be RM100? This is basically the corruption culture which is known for our country.

No I don't think they have to replace the entire length. The installation crew have with them a portable fiber optic splicing kit. Search for "fiber optic splicing" on Youtube.
I saw them using a fusion splicer on one visit at my uncle's place.
Not a good idea which needs a TM outsourced technician to attend and they can simply charged you repair fee as they wish else they give you a lousy service.I saw them using a fusion splicer on one visit at my uncle's place.
Did you know about optical power loss budget?
Allow me to tell you some "INSIGHTS" about TM HSBB setup. Many of its initial HSBB Phase 1 service areas actually FAILED to meet the requirements of ITU's GPON G984.2 B+ standard which allows gigabit GPON services to be deployed unlike in countries such as Thailand, Singapore, Japan and Europe.
As far as I know only the newer players such as Time, Maxis's own built fibre network and TNB's ALLO which was built later met the criterias of this standard. The most significant criteria was a maximum of using a 1:32 splitter. The earlier HSBB Phase 1 build out was using 1:64 splitters instead to cut cost at the expense of not being able to provide gigabit plans for future.
This is roughly how you calculate the total amount of power loss for your GPON line which you can more accurately measure with an OTDR meter at the FWS/TP port at your premise.
For the GPON G984.2 B+ standard the suggested power loss should not be more than 28dB.More stringent network buildouts allow a 5% reserved which limits it to only 26.5dB.
By estimation:
Fibre cable distance + Splitter ratio + Total number of connectors(readily spliced/mechanical based fast snap-on connectors) + Number of joints(fusion(melted)/mechanical)
*Also loops, temperature, environmental conditions and ageing of fibre must be considered for more accuracy.
Every splice you make in between the cable length from the OLT to the FWS results in power loss. The estimated power loss for each fusion splice is about 0.2-0.5dB.
Every kilometer of fibre length = 0.4dB loss
A 1:32 splitter roughly takes up 18dB loss, 1:64 splitter around 22dB loss
A fast mechanical snap-on connector introduce 0.5-1.0dB loss which is what TM used now to make the connector that plus into the ONT(fibre modem) after stripping the fibre cable.
Do note that fibre optic cables also age with time. Every year expect upto 0.7dB loss as it becomes older. It has about 20 years lifespan.
As you can see, the 1:64 splitter setup which TM used for their Phase 1 earlier NEVER met the ITU GPON G984.2 B+/C+ standards which is the minimum to allow gigabit plans to be offered to subscribers thus the reason why they could barely even sell 800Mbps plans.
Having a FWS actually introduces power loss as well but it allows quick swaps of patch cable between the wall socket and the fibre modem(ONT). It actually saves you the trouble of having to detect the entire cable length from the FDP box on the pole right to the connector that is inserted into the modem. If the cable is concealed and runs through your house's ceiling, imagine the amount of work needed to trace the fractures in the entire length?
