Fujitsu Enters North American GPON Market

Fujitsu Network Communications is expanding its North American access by introducing its widely deployed Gigabit Ethernet Passive Optical Networking (GEPON) systems from the Asian market. These systems will be complemented by its Multi-Service Access Node (MSAN) solution and IP Digital Subscriber Line Access Multiplexers (DSLAMs) from its U.K. deployment programs.



Fujitsu said its GPON architecture is designed to significantly lower the cost of deploying and operating passive optical networks, while providing seamless integration with both existing Time Division Multiplexed (TDM) networks and next-generation packet transport networks.



GPON supports downstream rates of 2.488 Gbps and upstream rates of 1.2 Gbps, allowing for bandwidth in excess of 75 Mbps per home. The use of generic framing in GPON, compared to ATM cells in BPON, also eliminates much of the external ATM legacy costs for service providers. Broadband Passive Optical Networking (BPON) networks are limited to 622 Mbps toward subscribers (i.e. downstream) and 155 Mbps from subscribers (i.e. upstream), with approximately 20 Mbps allocated per home.
