Sycamore Networks Expands Suite of Integrated Switching and Transport Offerings

Enhanced with OTN G.709 capabilities, Sycamore Universal Service Card to be
showcased in OIF Broadband On-Demand Global Interoperability Demonstration
CHELMSFORD, Mass.--(Business Wire)--
Sycamore Networks, Inc. (NASDAQ: SCMR) today announced the addition of Optical
Transport Network (OTN) capabilities to its suite of integrated switching and
transport offerings on the SN 16000 Intelligent Optical Switching Platform.
Already deployed in a Tier 1 carrier network, the industry-standard (ITU-T
G.709) interface module expands the rich feature set of Sycamore`s Universal
Service Card and provides network operators with additional tools to reduce
capital and operational costs while improving network efficiencies, reliability,
and end-to-end service interoperability.

The cost-effective Universal Service Card (USC) for the SN 16000 Intelligent
Optical Switching Platform supports - on a single card - a wide range of client
service rates and high-speed transport options, including Gigabit Ethernet, 10
Gigabit Ethernet, SONET, SDH, and in-service pluggable optics. Enhanced with the
OTN G.709 Line Interface Module (LIM), the full-featured USC further simplifies
the design, configuration, and deployment of different traffic types and
converged services over dynamic optical transport networks. Leveraging common
networking (BroadLeaf) and management (SILVX) intelligence shared by all
Sycamore optical switches, the Sycamore OTN solution brings a new level of
flexibility and efficiency to end-to-end, multi-service transport.

The OTN G.709 USC solution supports both the standard Forward Error Correction
(FEC) and enhanced FEC optimized for long distance transmission. The
standards-based OTN interface module also supports software configurable full
C-band tunable optics, which dramatically simplifies wavelength activation and
allows network operators to reduce the number of collocated DWDM equipment
(e.g., transponders, regenerators) in integrated switching and transport
applications. As a result, network operators can achieve significant cost
savings by reducing footprint, power, and sparing requirements as the network
scales. By further consolidating network functions using Sycamore`s OTN-equipped
USC, operators can also improve network reliability and enhance end-to-end fault
and performance management in multi-vendor networks.

Sycamore Participates in OIF Global Interoperability Demonstration

The Company also said it is one of ten leading telecommunications equipment
suppliers uniting under the banner of the Optical Internetworking Forum to
showcase multi-vendor interoperability in a multi-carrier environment at the
OIF`s Worldwide Interoperability Demonstration - Enabling Broadband On-Demand
Services. In addition to its industry-leading BroadLeaf control plane
technology, Sycamore will feature the SN 16000 Universal Service Card during
this dynamic multi-vendor interoperability event.

The OIF`s fourth worldwide interoperability test and demonstration will be
conducted simultaneously at carrier labs in China, Japan, France, Germany,
Italy, and the United States. The event highlights network-interoperable
solutions among participating equipment suppliers employing OIF UNI 2.0 and
E-NNI implementation agreements. The demo addresses Ethernet Virtual Private
Line (EVPL) Services over multiple, control plane-enabled intelligent optical
core networks with technologies ranging from Layer 2 transport to OTN.

This year`s OIF demonstration begins with intra-lab testing among each of the
seven participating carrier sites. The test sites are linked via virtual or real
E-NNI connections, forming a global test network topology. With the test phase
of the event underway since March, the demo will culminate in regional live
showcases at iPOP (June 11, Tokyo, Japan); OIF Carrier Day (June, USA); and IIR
WDM and Next Generation Networking (June 25, Nice, France, stand 24).

About the OIF

Launched in April of 1998, the OIF unites representatives from data and optical
networking disciplines, including many of the world's leading carriers,
component manufacturers and system vendors. The OIF promotes the development and
deployment of interoperable networking solutions and services through the
creation of Implementation Agreements (IAs) for optical, interconnect, network
processing and component technologies, and optical networking systems. The OIF
actively supports and extends the work of standards bodies with the goal of
promoting worldwide compatibility of optical internetworking products. Working
relationships or formal liaisons have been established with the Ethernet
Alliance, IEEE 802.3, IETF, ITU-T Study Group 13, ITU-T Study Group 15, IPv6
Forum, MEF, ATIS OPTXS, ATIS TMOC, Rapid I/O, TMF, UXPi and the XFP MSA Group.
