At its meeting this past July, the IEEE 802.3 Working Group launched a Study Group to investigate EPON specifications based on Google Fiber’s Super-PON technology. Google Fiber Architect Claudio DeSanti, chair of the new IEEE 802.3 Physical Layers for increased-reach Ethernet optical subscriber access (Super-PON) Study Group, told attendees of this month’s ADTRAN Connect media and analyst event that the technology enables a single central office to serve 1024 customer sites with a reach of approximately 50 km. Both specifications are greater than current EPON and GPON implementations, most of which support reaches of 20 km and subscriber counts of up to 64.
