EPON standard and issue
 Ethernet based PON was standardized by IEEE.
 To realize 10Gbps high-speed access network
 Enabling broadband applications such as Bi-directional Super High Definition Video,
Remote Education, Remote Healthcare, etc.
 However that standardization was limited in PHY and MAC layer thus preventing
EPON interoperability.

System level EPON standard
 In order to improve EPON interoperability, a system level
EPON standardization started in IEEE P1904.1 SIEPON
(Service Interoperability in EPON) WG since 2010 and it was
approved in June 2013.
http://grouper.ieee.org/groups/1904/1/
 SIEPON WG plans to conduct its Conformance Test and
issue Certificates (SIEPON Certificate Program).
 Moreover, SIEPON Package B, which is one of SIEPON
specifications based on Japan specifications, was consented
as ITU-T G.epon (G.9801) in July 2013.
 In order to promote EPON interoperability, HATS conference
organized Optical Access Ad-hoc WG.

G.epon/SIEPON Standards
 SIEPON is a system level standard for EPON.
 G.epon (G.9801) is a new ITU-T Recommendation that is ITU-T version of
EPON based on SIEPON Package B and adopts Generic OMCI, which is
common to various ITU-T systems, instead of eOAM.

SIEPON standard packages
 Packaged standardizations.
 It is hard to realize a unified set of specifications for realizing interoperability
among existing 1G-EPON devices because there are different specifications for
each vendor or carrier.
 SIEPON specifies 3 specification packages
 However SIEPON aims to realize a hardware commoditizing in order to absorb
differences by modifications of their firmware.

Demonstration system for optical access showcase
 Demonstrate interoperable 10G-EPON(10Gbps) system:
 3 ONUs (FUJITSU, MITSUBISHI, OKI) are connected to 1 vendor’s OLT and
the OLT will be replaced by another OLT.
 Data transmission will be kept even if the connected OLT is changed to
different vendor’s one.
