ADTRAN Introduces 10G-EPON Remote OLTs Supporting Both DPoE and SD-Access

Space and power saving sealed, virtualized OLTs uniquely support
integration into existing DOCSIS subscriber management systems

ADTRAN®,
Inc.
, (NASDAQ:ADTN), a leading provider of next-generation open
networking solutions, today introduced its environmentally sealed,
10G-EPON virtual Remote-OLTs (virtual R-OLTs), further broadening its software-defined
access (SD-Access)
portfolio. These new elements provide cable MSOs
the ability to further execute on their 10Gbps FTTH and SD-Access
strategies, while seamlessly integrating into existing DOCSIS back
office provisioning and operational systems. This unique combination of
three critical and field proven capabilities— DOCSIS provisioning of
EPON (DPoETM), native SDN integration and remote outside
plant packaging—enables ADTRAN to capitalize on evolving distributed
access architecture (DAA) deployments as cable operators look to
leverage next-generation FTTH to enhance support for high-bandwidth
services.

"Now, more than ever before, the network impact of supporting more
bandwidth is demanding service providers make a significant
architectural shift. The emergence of low latency augmented and virtual
reality applications is also forcing providers, including cable MSOs, to
reevaluate their network infrastructure," said Rupert Wood, research
director at Analysys Mason. "Distributed, Remote-OLT access
architectures, by moving FTTH electronics into the outside plant, afford
the operator a network that can support much higher access speeds and
subscriber capacity while also alleviating head end space congestion."

Traditional FTTH network growth required MSOs to overcome capital,
operational and regulatory hurdles, while requiring time-consuming and
costly permits for adding new fiber from the headend, which slowed their
ability to turn up services in a timely fashion. DAA and R-OLTs
alleviate many of these issues. Furthermore, ADTRAN R-OLTs integrate
field proven DPoE management methods and Layer 3 functionality, like
provisioning and routing, running on specialized components.

Alternatively, the Layer 3 and other functionality can be virtualized
affording additional cost reduction benefits as the R-OLT architecture
is simplified further. The ADTRAN OLTs bridge the management horizon
with support of both DPoE management and modern SDN control protocols
allowing MSOs to effectively execute over time their transition to
virtualized, managed and orchestrated SD-Access service architectures.

"ADTRAN's market leadership in outside plant (OSP) product design has
enabled us to successfully deploy hundreds of thousands of remote FTTx
systems in many of the world's harshest environments," said Hossam
Salib, vice president of cable and wireless strategy at ADTRAN.
"Combining this unique OSP experience with our field-proven, fully
standards-compliant DPoETM solution and our SD-Access
leadership uniquely qualify ADTRAN to meet the requirements of a range
of evolving DAA strategies."

ADTRAN
Mosaic
is facilitating the MSO community's transition to
standards-based SD-Access through distributed, virtualized
energy-efficient 10Gbps fiber architectures. The ADTRAN virtual R-OLTs
portfolio of multi-port 10G-EPON devices reduces time-to-market and
subscriber connection costs by using the desired FTTH and DAAs needed to
effectively deliver higher-speed triple play services. The ADTRAN 9504N
R-OLT has seamlessly integrated into existing DPoE systems while the SDX
6210-4 virtual R-OLT supports the ability to shift costly Layer 3
processing from the provider edge to the access network, resulting in a
paradigm shift in price and industry leading low power consumption for
R-OLTs.

ADTRAN will showcase these differentiated solutions at Cable-Tec
EXPO
in Denver, Colorado, on October 17-20, in Booth 2059 located
adjacent to the Events Lounge.
