Siemens Demonstrates Transmission Rates of 1.2 Tbit/s Over
One Optical Fiber
BOCA RATON, Fla.--(BUSINESS WIRE)--Feb. 22, 1999--Siemens has successfully tested
transmission rates of 1.2 Tbit/s over one optical fiber for the first time.
The test was conducted at Siemens' development center in Munich using Wavelength Division
Multiplexing (WDM) technology, a procedure for simultaneously transmitting different wavelengths
over one optical fiber.
WDM is the key technology for integrated telecommunication and data networks for extremely high transmission rates.
Sixty channels -- each with 20 Gb/s -- were simultaneously transmitted over an 80km long optical fiber. The 20 Gb/s channels were created with
the Siemens-developed Electronic Time Division Multiplexing (ETDM) process, which combines different signals by transmitting the data
streams in different timeslots on one line.
''Clearly this rare achievement demonstrates Siemens as a leader in optical networking technology,'' said Mike McLaughlin, vice president and
general manager of the Optical Networks Division for Siemens Information and Communication Networks Inc. ''This capability will lead to
future enhancements in our commercially available products such as TransXpress Infinity, our DWDM (dense wavelength division multiplexing)
long-haul transport solution.''
The new optical networks will enable ATM (Asynchronous Transfer Mode), Gigabit Ethernet, SONET (Synchronous Optical Network) and other
data formats to be transmitted alongside one another on different channels.
The networks feature Optical Add/Drop Multiplexers (OADM) which allow individual channels to be routed with a data throughput in excess of 1
Tbit/s. Siemens also is working on various OADM multiplexer variants. A field test supported by Germany's Federal Ministry for Education and
Research will be conducted which connects several high-end users in Berlin into an optical metro-WDM ring. Siemens expects the test to provide
knowledge relating to the concepts of OADM devices, optical protection switching and remote management aspects.
Optical Networks, a division of Siemens Information and Communication Networks Inc., designs and develops state-of-the-art optical transport
systems for the North American market. Since its inception in October 1997, the Optical Networks Division has launched two innovative optical
transport solutions. TransXpress ALine is a multi-service, local transport system that combines synchronous optical network (SONET) and
asynchronous transfer mode (ATM) technologies on a single platform. TransXpress Infinity is an ultra-high capacity, dense wavelength division
multiplexing (DWDM) transport solution that delivers more data at faster speeds over greater distances than traditional systems.
Siemens Information and Communication Networks Inc., headquartered in Boca Raton, Fla., is a leading provider of information and
