PMC-sierra PAS6301 EPON ONU介绍

Features

PRODUCT BENEFITS

Full IEEE 802.3ah EPON ONU functionality with integrated ARM9 CPU and comprehensive software package Includes support for CTC EPON technical requirements version 1.0 Advanced classification engine with support for VLAN, IP, TCP & UDP to provide true "triple-play" services A glueless interface to on-board limiting amplifier and laser diode driver providing an easy maintenance cost effective solution Advanced switch management capabilities including a standard MII interface and an L2 software management package (STP, IGMP, etc.) supporting various external switches A cost effective SDRAM based packet buffer with 8 queue priorities and up to 8MB of bursty traffic protection

An advanced Rate Limiter which can be operated in both upstream and downstream and can be configured to operate per priority queue, per the whole ONU, or per VID . An additional mode exists for upstream enabling the rate limitation of multicast and broadcast frames separately. Open Software development platform with support for Linux, VxWorks and a low footprint RTOS Integrated SERDES for EPON tranceiver connection Flexible optical transceiver interface for support of multiple vendors FEC coding for improved link budget Integrated encryption for enhanced security and privacy based on AES or churning Advanced threshold and queue level reporting to support high quality of service DBA algorithms

FEATURES

Gigabit Ethernet PON ONU based on 802.3ah standard Integrated SERDES and CDR for loop timing support FEC support for improved optical budget and split ratio Programmable interface logic for optical transceiver Integrated ARM9 CPU (including MMU) Complete ONU software package development platform supports automatic operation and OEM vendor extensions Support for buffer threshold reporting for compatibility with dynamic threshold control 8 priority queues with multiprotocol classifier including: VLAN manipulation and QOS support 802.1p priority, IPv6, IPv4 IGMP IP, TCP, UDP
