Ciena extends DWDM product family -- 40-channel DWDM system delivering 100 Gb/s of capacity.SAVAGE, Md.--(BUSINESS WIRE)--June 21, 1996--In a new thrust in dense wavelength division multiplexing See WDM. (DWDM (Dense WDM) The term given to wavelength division multiplexing (WDM) when significantly more channels were being added. Since WDM is increasingly more "dense" all the time, both terms are used synonymously. See WDM. DWDM - wavelength division multiplexing ) technology, Ciena Corp. announced Friday plans to introduce three additions to its Ciena MultiWave(TM) 1600 product line: a 40-channel (100 Gb/s capacity) terminal, an optical add-drop multiplexer Not to be confused with add-drop multiplexer. An optical add-drop multiplexer (OADM) is a device used in wavelength-division multiplexing systems for multiplexing and routing different channels of light into or out of a single mode fiber (SMF). (ADM See add/drop multiplexer. (language) ADM - A picture query language, extension of Sequel2. ["An Image-Oriented Database System", Y. Takao et al, in Database Techniques for Pictorial Applications, A. Blaser ed, pp. 527-538]. ), and a TMN-compliant native Q3 interface for network elements. "We recently announced a major network deployment of our MultiWave 1600 product line, which we will feature in a live demonstration, next week, at SuperComm 1996," stated Pat Nettles net·tle n. 1.

"Our decision to introduce these new additions to the MultiWave family represents the next step towards broadening our product line for high-capacity transport in the photonic layer," Nettles concluded. "Our advanced technology, including precision optical sources, narrowband optical filtering, and ultra-flat optical amplifiers, enables us to provide 40-channel DWDM systems with extremely narrow channel spacing The amount of bandwidth allotted to each channel in a communications system that transmits multiple frequencies such as fiber optics. It is measured as the spacing between center frequencies (or wavelengths) of adjacent channels. See guard band. ," said Steve Chaddick, vice president, product development of Ciena. Ciena's product vision includes transmission systems with many "express" channels, plus optional optical add-drop channels, each operating at rates of up to OC-48. Standard SONET optical interfaces terminate optical spans at each end, reflecting Ciena's "open systems at the photonic layer" approach. The optical ADM allows one to several OC-48 channels to be dropped and added along a route while remaining channels proceed through in an "express" format. This eliminates the need to terminate the entire optical layer at any intermediate site where access to a fraction of the total payload is needed. Cascadable with the same system performance as a standard optical line amplifier, the MultiWave ADM causes no degradation of the "express" channels. Consistent with the open systems approach, Ciena also announced the development of a native Q3 TMN (Telecommunications Management Network) A set of international standards for network management from the ITU. It is used by large carriers such as Sprint, Verizon and AT&T. interface for network management of Ciena MultiWave products. Part of the WaveWatcher(TM) network management family, the Q3 interface reflects the first information model derived from TMN M.3100 and Bellcore GR 1042 for DWDM transmission systems. Both NE layer and Element Management Layer interfaces are supported by WaveWatcher. Applications for MultiWave products are found in traditional long-haul and interoffice in·ter·of·fice adj.

Ciena's initial product offering, the Ciena MultiWave 1600, is a DWDM system capable of transmitting up to 16 discrete optical channels over one fiber. Each channel is bit-rate transparent from 150 Mb/s to 2.4 Gb/s and operates with existing SONET/SDH/Asynch fiber optic terminals. This system incorporates optical line amplifier repeaters to extend the transmission range, and it offers integrated network A network that supports both data and voice and/or different networking protocols.

These systems unlock fiber bandwidth, improve network reliability and significantly reduce the cost of providing new broadband services. Ciena is providing real-life solutions today to combat the emerging bandwidth and capacity needs long-distance carriers will be faced with tomorrow. CONTACT: Ciena Corp.
