Its not that TM cannot lay fiber, the problem are costs and local council making it super expensive and slow. There was a TED talk with representative from one of the local telcos explaining the problem with internet in Malaysia, his points were simple:
-Lack of competition - local councils charge a lot to lay cable and are very demanding (work ends up taking too long and costing too much too) - international bandwidth
If the locals band together as shown in the link, it will be very easy for fiber optics to spread. If the ISP and cables were separated like in japan, that would help too.
Not sure if this is the talk you are referring to. Nevertheless t's a good watch.
Bear in mind that this is from 2010.
yup, this is the video. It may be from 2010 but is still relevant today. There may more choices of ISPs but the whole process of laying cable and expending is difficult for an ISP, that is why TIME only does tall buildings mainly as many condos already do their own fiber optic wiring so ISP only has to connect building to the street which makes it easy and cheap for ISP to provide a connection. The process itself just to get cable onto the street, or a backbone through an existing infrastructure can be costly and difficult because of the red tape like the local councils and any other organisation involved.
