Summary

Recommendation ITU-T G.9801 describes requirements and specifications of Ethernet passive optical network (EPON) systems using the ONU management and control interface (OMCI), which is called OMCI-EPON.

OMCI-EPON is based on IEEE 802.3 and IEEE 1904.1 for user data transport, and applies Annex C of Recommendation ITU-T G.988 for its management. OMCI-EPON supports 1G-EPON, 10/1G‑EPON and 10/10G-EPON architectures defined in IEEE 802.3, and provides a mechanism that enables coexistence with the existing PON systems using time division multiple access (TDMA) technologies and/or wavelength blocking filter (WBF).
