ADVA OPTICAL NETWORKING INTRODUCES OPTOJACK

Optical demarcation capability enables service providers to deliver
differentiated, intelligent optical services

Norcross, Georgia, USA and Martinsried/Munich, Germany.
September 29, 2008. ADVA Optical Networking today introduced
Optojack®, a new technology that enables the establishment of
intelligent optical demarcation points to monitor advanced optical
services. Optojack provides optical demarcation and service
monitoring at the handoff point between carrier networks, as well as
at the demarcation point between the carrier and customer network.
Optojack is designed to enable remote Operations, Administration and
Maintenance (OAM) of key optical network elements in the access and
backhaul portions of the network.

Analogous to ADVA Optical Network's successful Etherjack® technology,
Optojack provides the ability to monitor and test wavelength-based
services, a missing service provider requirement today. Frequently,
providers deliver optical services to customer locations without any
visibility into the health or status of the delivered traffic. In
addition, during turn-up or test, there is no way to perform the
loopbacks and remote testing from which most other non-optical
services benefit. Without a clear demarcation point that delineates
one carrier's network from the next, or the carrier network from the
customer's, it is challenging for the provider to cost-effectively
monitor, manage and troubleshoot an optical service.

With Optojack in place, a service provider can monitor the optical
signal all the way to the access equipment (e.g., a DSLAM (Digital
Subscriber Line Access Multiplexer) at the curb or in a building) or
customer device (e.g., Local Area Network (LAN) router). It can also
be more certain of the quality of service provided across multiple
carrier regions. Using Optojack functionality, carriers gain
important knowledge about when optical service degradations or
outages take place and, in some cases, can identify service problems
before the customer is aware they exist. Importantly, problems can be
fixed before they cause a complete outage, contributing to the
delivery of higher service availability levels.

"Due to the competitive nature of our industry, intelligence about
the network and the service can be a service provider's secret
weapon," commented Dr. Christoph Glingener, chief technology officer
(CTO) of ADVA Optical Networking. "Optojack is an invaluable tool to
help carriers offer differentiated services to a demanding customer
base. No matter the underlying protocol, Optojack enables loopbacks
and other key performance monitoring techniques that provide insight
into network services. This can lead to higher profit levels at a
time when carrier budgets are squeezed from every direction."

Optojack is a Small Formfactor Pluggable- (SFP) transceiver-based
solution, which is compliant with the MSA (SFP MultiSource Agreement)
and can be integrated into any SFP-based equipment, including ADVA
Optical Networking's flagship FSP 3000 and FSP 150 solutions. Other
network devices, like Optical Network Units (ONUs) that provide the
link to the customer premise, can also utilize the SFP, enabling
Optojack to play a critical role in successfully managing the entire
access portion of the network. In addition, a specific loopback
option enables the Optojack functionality to interoperate with any
device using standard-based SFPs.

To complete the solution, Optojack technology can be managed remotely
with ADVA Optical Networking's FSP Network Manager (NM) to provide a
total test and monitoring solution from the core or regional network
all the way out to the optical demarcation point. This integrated
solution enables delivery of intelligent optical services instead of
"best-effort" unmonitored services.
