Passave Unveils EPON System-on-Chip

Passave introduced its third generation, highly integrated chip for Ethernet passive optical networking (EPON) optimized for low-cost, high-bandwidth customer-premise installations on FTTH networks. The new device incorporates a CPU, MAC (media access controller), SERDES (serializer/deserializer), Layer-2+ switch and packet buffer on a single chip. The device also includes an advanced packet-classification engine for auto-provisioning of network resources.

Passave said its new product could be used for low-cost residential gateways that deliver services such as HDTV, VoIP, interactive gaming and other high-bandwidth services over a single connection. Like its predecessor, the new chip conforms to the recently ratified IEEE 802.3ah standard for Ethernet in the First Mile (EFM). Passave also provides a central-office (CO) chip, which works in tandem with the CPE device.

Passave's previous PON chipsets have been adopted by more than 20 global networking OEMs for PON systems currently in mass deployment, and have shipped in hundreds of thousands. http://www.passave.com
