New IEEE 802.3bk™ Amendment Designed to Enable Higher-Density, Longer-Reach EPON Applications with Improved Cost of Ownership
PISCATAWAY, N.J. --(Business Wire)--
IEEE (News - Alert), the world's largest professional organization advancing technology
for humanity, today announced the approval of IEEE 802.3bk™ "Standard
for Ethernet Amendment: Physical Layer Specifications and Management
Parameters for Extended Ethernet Passive Optical Networks." This
amendment to IEEE 802.3™ "Standard for Ethernet" is intended to enable
higher-density and longer-reach applications of Ethernet Passive Optical
Networks (EPON), while optimizing the costs of ownership for network
"As operators around the world seek to build higher-density and more
cost-effective optical access networks that connect more customers,
service providers are grappling with a number of scalability challenges
associated with delivery of mobile backhaul and guaranteeing
connectivity to remote customers," said Marek Hajduczenia, chair of the
IEEE 802.3bk Extended EPON Task Force. "The development of IEEE 802.3bk
was an open, market-driven effort to amend the Ethernet standard to
allow a given EPON deployment to support more users over longer
distances than previously possible."
Since the standardization of 10 Gb/s EPON (10G-EPON) in IEEE
802.3av™-20091, deployments of technologies based on the
standard have intensified among large network operators. With the
commercial success of 1G-EPON and the commercial availability of its
higher-speed version, 10G-EPON, new areas for improvement were
identified, such as addressing cost-effective application of EPON in
rural areas with lower customer densities, increasing subscriber density
per port in the central office, sharing available links among larger
concentrations of users and serving users distant from the nearest
network hub. IEEE 802.3bk addresses these issues by amending the base
IEEE 802.3 Ethernet standard to support optical loss budgets in excess
of those previously specified for EPON. In this way, IEEE 802.3bk is
designed to enable the expansion of the EPON service area, while
reducing cost per subscriber. Additional intended benefits of the
extended EPON include reduction in the footprint and power consumption
of central office equipment (per customer) and the cost of service
upgrades and fiber deployment, as well as an increase in customer
density per central office.
"We're excited about new IEEE 802.3bk-based products that will allow
service providers to make better use of their already deployed fiber,
increasing the number subscribers that can be served per OLT (optical
line termination) port," said Edwin Mallette, distinguished engineer,
network architecture and standards, with Bright House Networks. "This
will significantly reduce the overall cost of delivering services over
an EPON-based first-mile optical access. We are also looking with
interest at future projects within the IEEE 802.3 working group aiming
to define a next generation of EPON, primarily from the perspective of
compatibility with our fiber-optic distribution network that supports
1G-EPON and 10G-EPON today. We hope that this next-generation EPON, once
finished, will provide a cost-effective solution for a higher-speed
"The IEEE 802.3bk-2013 amendment provides the leap forward in the
capabilities of today's EPON deployments, allowing operators to serve
more customers on a single optical interface in the central office,
while keeping the cost-effective and service-oriented architecture of
EPON unchanged," said David Law, chair of the IEEE 802.3 Ethernet
Working Group and distinguished engineer with HP Networking. "While
extending capabilities of existing EPON deployments, the market-drive
innovation for EPON as the optical access technology continues. We are
already seeing interest in defining the next generation of EPON, and we
will be looking at service provider requirements and the state of
optical access technologies to provide a cost-effective evolution path
for EPON into the future."
Added Paul Nikolich, chair of the IEEE 802® LAN/MAN Standards
Committee (LMSC) and IEEE fellow: "Using IEEE 802 LMSC's highly
transparent and open process, the IEEE 802.3bk Extended EPON
participants provide an excellent example of how a focused technology
community can efficiently produce a high-quality standard to facilitate
the deployment of increasingly higher-performance, cost-effective
networks for both operators and consumers. Well done."

Deployment of technology defined by IEEE 802® standards is
already globally pervasive, driven by the ever-growing needs of networks
around the world. New application areas are constantly being considered
that might leverage the IEEE 802 family of standards in their networks.
To better address the needs of all of these areas, IEEE 802 standards
are constantly evolving and expanding. The success of IEEE 802
standards-from their inception through today-has been their fair, open
and transparent development process.
