Two Key Component Manufacturers Select EMCORE CWDM VCSELs for 10 Gbps Transcievers
Performance and Uniformity Major Factors in Selection of EMCORE Products
SOMERSET, N.J., May 16, 2001 (BUSINESS WIRE) -- EMCORE Corporation (NASDAQ: EMKR chart, msgs) has announced the availability of a family of Course Wavelength Division Multiplexing (CWDM) VCSELs for high-speed data communications. The family of CWDM VCSELs, which consists of four oxide VCSELs with wavelengths of 778nm, 800nm, 825nm, and 850nm, have been selected by Blaze Network Products and Cognet MircoSystems for use in their CWDM modules. Each VCSEL operates at 3.125 Gbps for an aggregate bandwidth in excess of 10 Gbps. The very tight control of wavelength required for CWDM applications can be achieved using EMCORE's renowned TurboDisc(R) Tools, which provide tremendous repeatability and reproducibility within the VCSEL growth and fabrication process.
A key benefit of using EMCORE's VCSELs for CWDM applications is the stability of wavelength over an operating temperature range from 0(Degree) to 90(Degree) C. The minimum shift allows for cost reduction by eliminating the need for temperature controls required with typical WDM lasers. The EMCORE oxide VCSELs also offer an advantage in power utilization. With thresholds averaging 2mA per VCSEL and typical slope efficiencies of .5mW/mA, light output of 2mA or more can be obtained with minimum power usage.
Blaze Network Products is using the 4 CWDM VCSEL devices to drive the development of CWDM modules for short reach (10 Gbps/OC-192) and extended reach (1 Gbps) data communication applications. In addition, EMCORE has announced that Cognet MicroSystems, which recently became a division of Intel, is currently using EMCORE's CWDM VCSELs for use in its high-speed data communications module for short reach applications.
Blaze is the first commercial venture to exploit WDM for short wavelength and data communications applications. The 10 Gbps module, which was designed for optical connect applications under 300 meters, including Local Area Networks (LANs) such as Gigabit Ethernet and Fiber Channel, is the first of its kind in the marketplace.
Brian Peters, President of Blaze Network Products comments, "EMCORE's VCSEL devices, which are one of the essential elements of our CWDM 10GB modules and key to their performance, have provided us with reliability, flexibility and high performance. These attributes have aided our mission to be the first to market with the smallest pluggable 10 Gigabit transceiver in the industry, enabling Blaze to set the standard, while other manufacturers design around these baseline performance characteristics."
Using the existing multimode fiber infrastructure CWDM transceivers can transmit 10 Gbps of data down a single multimode fiber. Bahram Jalali, President and CEO of Cognet Microsystems noted, "Short wavelength CWDM is an attractive technology for extending the reach of multimode fibers. The availability of CWDM VCSELs from EMCORE is the first and enabling step in the development of multimode CWDM modules."
According to Dr. Hong Hou, Vice President of EMCORE's Optical Device Division, "VCSELs are ideal for CWDM applications because of the repeatability and reproducibility of the manufacturing process. WDM applications have very tight tolerances. With the robust VCSEL design and tight manufacturing controls EMCORE can provide an ideal solution for high-speed data communications."
Oxide VCSELs have a very fast intrinsic speed and very high uniformity (EMCORE has demonstrated rates of up to 12.5 Gbps); therefore, only small alterations were necessary to create these new products. EMCORE was the first vendor to produce oxide VCSELs in commercial quantities and has expanded its oxide VCSEL product line to accommodate several datacom applications, including Gigabit Ethernet, Fibre Channel, OC-192 and OC-768.
