Much has transpired over the past several years for passive optical network (PON) technology. The era of higher speed PON will soon be upon us as the IEEE 802.3ca Task Force puts the finishing touches on the standard for 25 Gb/s PON and 50 Gb/s PON. This paper discusses the next generation of IEEE optical access, the 50 Gb/s Ethernet Passive Optical Network (50G-EPON), capable of symmetric or asymmetric rates up to 50 Gb/s while coexisting with legacy PON technologies on the same optical distribution network.
