SYCAMORE
NETWORKS ACQUIRES SIROCCO SYSTEMS FOR METRO ACCESS
Sycamore Networks will acquire Sirocco Systems, a start-up
developing optical access equipment for metropolitan area
networks, for approximately $2.9 billion in stock. Sirocco is
developing an Optical Service Delivery Network (OSDN) platform
with full packet/cell switching and processing capabilities, DWDM,
synchronous cross-connection and grooming, as well as a sub-lambda
switching fabric that allows each port or wavelength to support
multiple simultaneous services. The platform allows multiplexing
of multiple service types onto a single wavelength (sub-lambda
multiplexing) and it provides switching of sub-lambda streams at
each node (sub-lambda-switching). Stream merging capabilities
would enable large numbers of DS1/E1, DS3, OC-3/STM-1 streams of
IP traffic, ATM traffic and Private Line traffic to be
concentrated prior to being handed off to core routers and
switches. Sirocco’s
product line-up includes Optical Access Devices (OADs), which are
designed for deployment in the Metro or Access layer of the
network in central office, multi-tenant buildings and high-end CPE
applications, amd Optical Edge Switches (OES), which aggregate,
concentrate and groom multi-service streams on multiple
wavelengths directly into the optical core. http://www.siroccosystems.com/

In
December, Sirocco closed a second round of financing with the
backing of Weiss Peck & Greer Venture Partners, Bessemer
Venture Partners and Greylock Ventures. The company is led by
Jonathan Reeves, who previously was the founder and CEO of Sahara
Networks, an early developer of ATM access systems which was
acquired by Cascade/Ascend/Lucent. Sirocco is based in
Wallingford, CT and was founded in January 1999.
OPTICAL
MERGERS/ACQUISITIONS
MARCONI
INTEGRATES OPTICAL CROSSCONNECT, ADM AND SWITCH/ROUTER
Marconi introduced a next generation Multiservice Carrier
Node that combines the functionality of an optical cross-connect,
add-drop multiplexer and data switch/router with support for DWDM.
The Marconi MCN-7000 collapses multiple platforms into a
single box serving as a high-density SONET access and transport
edge device. It
supports a range of interfaces (DS1 and DS3, and optical signals
from OC3 to OC192) and services (including Ethernet, Frame Relay,
IP and ATM). Marconi
said its design would significantly reduce equipment costs for new
carriers, while introducing new flexibility for SONET.
Commercial availability is expected next month with support
for OC-48 rates. Future
releases will introduce OC-192 (10 Gbps) capabilities, full packet
switching and DWDM support. http://www.marconi.com/news_events/press_releases/current/4510.html

LUCENT
INTRODUCES FTTH ACCESS SOLUTION
Lucent Technologies introduced fiber-to-the-home and
fiber-to-the-curb devices for full-service access networks.
The bidirectional optical networking units (ONUs) integrate
video receivers and data transceivers that consume less than two
watts of power. The fiber-to-the-curb ONU can receive up to 110
cable channels over a one-gigahertz (GHz) downstream path, while
the fiber-to-the-home ONU can also receive 192 direct-broadcast
satellite (DBS) channels (transmitted from a dish at a service
provider's head-end or central office) over a two GHz path. Both
units support bidirectional data at rates up to 100 Mbps for
telephony and Internet access. Lucent said its products
incorporate a new wavelength multiplexer design that is
significantly less expensive than WDM technologies used in optical
transport networks. http://www.lucent.com/press/0600/000606.mea.html

LUCENT
PREVIEWS SMALLER NEXABIT SWITCH/ROUTER, ENHANCES GX 550 ATM SWITCH
Lucent Technologies introduced a Multi-Terabit Switch
Router designed for small regional networks.
The NX32000 offers 3.2 terabits of total capacity, supports
up to eight OC-192 slots and integrates DWDM optics into the
product. The system
is a smaller version the existing NX64000 (Nexabit) product
introduced earlier.
Lucent Technologies also announced major enhancements for
its GX 550 ATM switch, including new switch processors, improved
circuit density and optical packet interfaces supporting MPLS,
Frame Relay and enhanced QoS.
The new interfaces include OC-3/STM-1 Packet & Frame
over SONET/SDH, OC-12/STM-4 Packet & Frame over SONET/SDH, and
Gigabit Ethernet/IP/MPLS.

NORTEL
NETWORKS OUTLINES "VIRTUALIZED NETWORK" VISION
Nortel Networks introduced a new "Virtualized
Network" plan to enable subscriber-aware services, including
instant user recognition from any location or port, preferred
customer status, hosted applications, and new levels of control
and personalization. The capabilities would be implemented using
Nortel Networks' Preside tools integrated with customer premise
equipment, as well as Nortel's network-based VPN portfolio
including Passport, Shasta 5000 BSN, Contivity, CVX and Versalar*
technologies.
Nortel also announced new Network Intelligence capabilities to
enable service providers to dynamically monitor network
conditions, and to automatically shift network resources for
content-optimized delivery. http://www.nortelnetworks.com/corporate/news/newsreleases/2000b/06_06_0000306_vn_oni.html

INTEL
INTRODUCES 7 OPTICAL SILICON CHIPS
Intel announced seven new optical networking chips created
through its acquisitions of GIGA A/S in March of this year and
LevelOne in August 1999. The
devices include: a chipset for network interconnect devices such
as bridges and gateways operating at OC-3, OC-12, OC-48 and
Gigabit Ethernet line rates; a single-chip OC192 Forward Error
Correction (FEC) device; a multiplexer that enables an OC192 to be
divided into four separate OC48 lines; two multirate, multiservice
framers capable of handling both packet and cell data running on
ATM, Frame Relay or Ethernet protocols; and a 28 channel SONET/SDH
mapper.

NORTEL
NETWORKS AND AT&T TO BEGIN GPRS TRIALS IN MAJOR US CITIES
AT&T Wireless Services will conduct
non-commercial trials of General Packet Radio Service (GPRS) core
networks, part of the 3G TDMA-EDGE architecture, in several major
US cities beginning this summer. Nortel
Networks said its GPRS platform would enable full ISP services,
including secure mobile VPNs created with its Passport, Shasta and
Contivity Extranet switches.
The trials will provide live experience for when full 3G
TDMA-EDGE technology becomes commercially available. 3G TDMA-EDGE
is expected to increase throughput and spectrum efficiency by up
to three times over GPRS, enabling wireless data transmission at
speeds up to 384 kbps. http://www.nortelnetworks.com
