Fiber to carry POTS? (semi off topic)

Does anybody know of a way to extend POTS over fiber? I need a way to bring 25 pair into a device that will allow me to extend them over fiber to another device that will allow me to break them back out to copper pairs.

Hi

Well an FXO and a FXS gateway and a couple of fibre tranceivers should do the trick. Ive done this to extend paging and pots interfaces
