EPON/IEEE 802.3ah is a 1-Gigabit system (actually a 1.25 Gbps but 20% is used by the 8B10B encoding); I haven't seen any spec for a 10-Gig PON; even recently standardized GPON is limited to 2.5 Gbps downlink, 1.25 Gbps uplink. > You might look at alloptic as a equipment provider here > http://www.alloptic.com/ Or http://www.alcatel.com/fttu http://www.flexlight-networks.com/ http://www.broadlight.com http://www.teknovus.com Rubens
