its not on their site but if u go to their exchange and ask them they can give u info on it

in fact i think a few ppl in this forum have ONU lines maybe u can ask for reviews in the ptcl thread

ONU is fiber optic and ptcl install at exchange level to other point but not at customer place. customer will get copper wire from that point to thier location. And copper wire is actually not 100% copper wire which comes to customer location. There is no cost of opting to ONU because by default PTCL is replacing copper to ONU/fiber optic. I dont know what is the meaning of ONU but they call ONU instead fiber optic as I talked PTCL staff.

ok in a normal copper line a copper line comes to ur home from the exchange right

in an onu ptcl has fibre goin from their exchanges and they have cabinets all around the city

and from those cabinets copper lines come into our home

thus the reliance on copper is reduced

this is similar to FTTN http://en.wikipedia.org/wiki/FTTN#Fiber_to_the_node

ok i knew abt that thing. didnt know ptcl was deploying it.......

so ithink its time 2 bribe the line men..... hes a good buddy of mine no tention......
