PRODUCT OVERVIEW
PAS65311 is a reference design for a GPON ONT, based on PMC-Sierra's
PAS6201-G0 GPON SoC and PAS6211 GPON Framer/Serdes. The
solution is based on PMC-Sierra's GigaPASS architecture and PAS6201
ONU SoC, which is the first PON SoC to be deployed in millions. The
GigaPASS architecture integrates multiple hardware-based packetprocessing
engine subsystems to deliver wire speed packet
processing at all packet sizes, and combines them with a control
processor supporting Linux and VxWorks operating systems and
extensible middleware platforms. This solution performs QoS queuing,
packet classification, VLAN bridging and manipulation and IPTV
filtering at full-duplex line rate, in order to provide predictable,
sustainable and guaranteed performance, to assure delivery of tripleplay
and QoS-sensitive applications under all traffic and service
network conditions.
PAS65311 is designed to support a variety of ONT types, including
Single Family Unit (SFU), Multi-Dwelling Unit (MDU) and Multi-Tenant
Unit (MTU) types.
It is supplied with complete software, including a full OMCI stack,
TR069 stack, VoIP software, and optional Ethernet OAM.
