Optic Fiber for PTCL DSL? plus Smart TV

I am currently using PTCL's DSL (512 KB) on a copper wire. Normally get download speeds of around 35-40 KBPS. Should I convert the line to optic fiber?

Secondly, I've been told that I can subscribe to PTCL Smart TV because of distance from the exchange. Any other way I can do this? ( I know it cannot be done on optic fiber anyway at the moment)
