Opulan Technologies has introduced broadband-access solutions that consist of 10Gbps EPON (Ethernet passive optical networks), OpconnT and cableTV SOCs and ASSPs. The Opulan 10Gbps EPON solution has successfully passed chip-level interoperability testing organised by China Telecom. The main benchmark testing performed included - MPCP discover, register and ranging; DBA; scalable OAM; and backward compatibility with 1G EPON - the key requirements in IEEE802.3av and China Telecom specifications.Opulan's solution is FPGA based and achieved downstream data flow at 9Gbps and upstream at 950Mbps under an asymmetric model. After smooth testing, Opulan's Opconn 1G EPON SOC will commence full production. The Opconn is a client-side ONU SOC of an EPON solution. Opulan's engineering team has completed thorough product and interoperability testing against IEEE802.3ah and China Telecom EPON standards.
The ONU SOC features an embedded MIPS4kec processor for board-level control and management; a powerful Ethernet switch and dynamic bandwidth allocation (DBA) engine that offers wire-speed processing; IEEE802.1ad and 802.1q Bridge; flow-based QoS classifier, and hardware-based AES-128/Triple churning encryption module. Opconn can work under three common scenarios.
It can be an uplink for Opulan's cableTV-based EOC solution, carrying traffic from CATV broadband subscribers; it can backhaul Opulan's IPMux-based xDSL traffic aggregation; and it can be the final POP of a service provider directly connecting FTTH (fibre to the home) clients.
