PAS5211 GPON OLT

Product Overview

The PAS5211 is a four-port Gigabit PON Optical Line Terminal (OLT) System-on-Chip (SOC) dedicated for use in a Gigabit Passive Optical Network (ITU-T G.984 GPON). The PAS5211 chip integrates GPON Media Access Control (MAC) functions, GPON protocol management, IEEE 802.1ad-compliant VLAN bridge, Ethernet MAC functions, and an embedded CPU subsystem.
