IEEE Launches New Effort to Advance Ethernet Passive Optical Network (EPON) Protocol over Existing Coaxial Distribution Networks
PISCATAWAY, N.J. --(Business Wire)--
IEEE (News - Alert), the world's largest professional association advancing technology
for humanity, today announced it has launched a study group to
investigate a new PHY (Physical Layer) standard for operating the
Ethernet Passive Optical Network (EPON) protocol transparently over
coaxial distribution networks. The newly formed IEEE 802.3TM EPON
Protocol over Coax (EPoC) Study Group will explore using the IEEE 802.3
Ethernet specifications to significantly boost and broaden the
capabilities of Ethernet in existing access networks that currently
serve hundreds of millions of residential and business subscribers
around the world.
IEEE 802.3 EPON is the market-leading fiber-access technology, and has
shipped more ports than any other IEEE 802.3 technology defined in the
last 10 years, with worldwide deployments supporting more than 60
million subscribers today and an anticipated subscriber base of more
than 100 million by the end of 2013. These systems support a diverse
suite of business and residential services, including IPTV (News - Alert) (Internet
Protocol Television), VoIP (Voice-over-IP), commercial-grade data
services, and mobile backhaul. IEEE 802.3 EPON specifications include
symmetric data rates of 1 Gb/s and 10 Gb/s, as well as asymmetric data
rates of 10 Gb/s downstream and 1 Gb/s upstream.
"Operating EPON transparently over coax is a significant step forward.
It will help to transform the industry by greatly simplifying operator
networks while simultaneously offering subscribers easy and efficient
access to dramatically increased bandwidth," said Howard Frazier, chair,
IEEE 802.3 EPoC Study Group and senior technical director, Broadcom (News - Alert)
Corporation. "The ability to leverage existing Ethernet infrastructures
and cable plant investments while offering a ten-fold increase in data
speeds is revolutionary."
In many locations around the world, fiber stops at the street, basement,
or curb with coaxial cable spanning the remaining distance to the
subscriber, a significant percentage of hom are in multiple
dwelling/tenant units. Pulling fiber is expensive and time consuming and
Multiple Service Operators (MSOs) must find ways to lower the cost of
upgrading their networks. The new IEEE 802.3 effort will directly
address the needs of cable operators who want an end-to-end Ethernet
network capable of efficiently supporting next-generation services such
The IEEE 802.3 EPoC Study Group enjoys the support of a diverse
community of stakeholders from around the world, including components
vendors, network equipment suppliers, cable operators, and MSOs.
"This effort is an industry pull not a technology push. We are pleased
with the enthusiastic reaction we've received from industry who have
turned to the IEEE specifically to investigate the potential for using
the IEEE 802.3 EPON protocol on existing coaxial cable networks," said
David Law, chair, IEEE 802.3 Working Group and distinguished engineer,
The IEEE 802.3 EPoC Study Group will explore market demand, network
compatibility considerations, and available technologies for a PHY
specification for operating the IEEE 802.3 EPON protocol over coaxial
distribution networks. The IEEE 802.3 EPoC Study Group will meet for the
first time in January 2012, with the expectation that results from the
investigation could be completed by July 2012.
