                                                                                                                                -----NTW-E18008C

Based on the Ethernet standard 802.3, EPON 802.3ah specifies a similar passive optical network with a range up to 20 km. EPON uses WDM with the same optical frequencies as GPON and TDMA. The raw line data rate is 1.25 Gbits/s in both the upstream and downstream directions.

EPON technology

EPON technology provides bidirectional 1Gb/s links using 1490nm wavelength for downstream and 1310nm wavelength for upstream, with 1550nm wavelength reserved for future extensions or additional services. EPON is fully compatible with other Ethernet standards, so no encapsulation or conversion is necessary when connecting to Ethernet-based networks on either end. The same Ethernet frame is used with a payload for up to 1518 bytes. As Ethernet is the primary networking technology utilized in local area networks (LAN) and now in metro area networks (MAN), no protocol conversion is needed.

Advantages of Optical Ethernet (EPON)

• Low cost due to economies of scale

• ~320,000,000 Ethernet Ports deployed worldwide

• LANs are ~90% Ethernet today • Byte life begins and ends as IP/Ethernet

• Ease of Scalability, Management •

Cable Modems and DSL Modems have Ethernet Interfaces

• Many IP/Ethernet chipset solutions to chose from

• Future cost curve of components (electrical, optical) steep for Ethernet

• Ethernet is a Universal standard, no variations • CLECs (ELECs) can start with IP centric networks

• Carriers are now offering Ethernet WAN Services

• Ethernet beat FDDI, Token Ring, Fibre Channel, ATM in the LAN

• Work force Solution: Many LAN technicians comfortable with Ethernet
