PON History

• Initial PON (1990s) were based on ATM framing (APON, BPON)• ATM-based BPON were inefficient, majority of traffic through the access network

was IP traffic.

• Ethernet based PON (EPON), QOS-aware Gigabit Ethernet (GbE) (VLANs,

prioritization, OAM) and integration with other Ethernet equipment.

• Gigabit-capable Passive Optical Network (GPON) proposed by FSAN

members (Quantum Bridge et. al) - dual Gigabit speed ATM/Ethernet PONto IEEE 802.3ah – had to continue this work within the ITU.

• EPON and GPON both draw on G.983, the BPON standard• (PON operation, ODN framework, wavelength plan, and application)

• designed to better accommodate variable length IP frames at Gigabit line rates.

EPON & GPON Basics

Ethernet Passive Optical Network (EPON)

Sometimes called GEPON (Gigabit Ethernet Passive Optical Network)

IEEE 802.3 standard, ratified as 802.3ah-2004 for 1Gbits/s

IEEE 802.3av standard for 10Gbits/s

Uses standard 802.3 Ethernet data frames

Gigabit Passive Optical Network (GPON) ITU Standard G.984

Downstream 2.488Gbits/s, Upstream 1.244/2.488Gbits/s

ITU Standard G.987 for 10Gbits

Downstream 10Gbits/s, Upstream 2.488/10Gbits/s

Uses GPON Encapsulation Method (GEM), fragmented packets or ATM(most implementations use GEM as ATM is expensive)
