The Cortina Systems® CS8021 Quad Gigabit Ethernet Passive Optical Network (GEPON or EPON) Optical Line Terminal (OLT) chip (CS8021) supports four EPON ports in a single chip to significantly simplify board design and lower the system Bill of Materials (BOM) cost. The CS8021 enables equipment vendors to develop a high port density chassis or stackable rack mount system targeted at the Central Office (CO).

• Emulates point-to-point link between each ONU and OLT using LLID (logical link identifier)
• Supports single-copy-broadcast (SCB)
• Supports ONU-to-ONU communication and emulates LAN service using layer 2 MAC address
• Supports standard based as well as vendor specific registration and deregistration process
Ethernet OAM Management
• Implements complete IEEE 802.3ah OAM functions
• Supports bridge/Ethernet MIBs
• Supports EFM MIB
• Supports EFM OAM MIB
