Providing integrated services with broadband PON

This paper discusses the network architecture for delivering voice, data, and video signals over broadband passive optical networks (BPON). We, first, explain BPON physical and media access control layer protocols. Then, we summarize the network configuration for carrying voice, data, and video. In particular, the necessary equipment and interfaces upholding these functions are introduced. Finally, we examine closely its limitation on transporting analog video signals in a wavelength overlay. This paper concludes that BPON can support around 400 TV channels with 64QAM using cost-effective optical components. Yet, it is limited to 30 or so analog channels with AM-VSB even with "ideal" optical components. The paper also highlights the current standardization effort in FSAN and its initiatives on future BPON enhancements.
