CALABASAS, Calif. -- E2O Communications Inc., a leading provider of high-performance fiber optic transmission components for both data communications and telecommunications applications, today announced a breakthrough in technology development with its electrically pumped Long Wavelength Vertical Cavity Surface Emitting Laser (LW VCSEL) technology, capable of generating laser wavelengths from 1270 nm to 1610 nm for LAN, metro, data communications and telecommunications applications. The technology was introduced at last week's IEEE LEOS'03 annual meeting in Tucson, AZ, in a post-deadline paper, authored by several of E2O's research and development team. This low-cost, high-performance technology is currently being designed into optical transceivers for production in 2004.

E2O's research and development team has developed the LW VCSEL for 10 Gigabit Ethernet, fiber channel and other applications in LAN, SAN, MAN and access networks. The company has already demonstrated data transmission using these LW VCSELs at both 10.3 Gbps and 4.25 Gbps on a 10km of single mode fiber, at 10.3 Gbps on 100 m of 62.5 um core diameter multimode fiber, and at 3.125 Gbps on a 300 m of the 62.5 um core diameter multimode fiber.

"E2O's development team has leveraged a conventional active materials system with proven reliability to develop the LW VCSEL," said Dr. Julian Cheng, head of the long wavelength VCSEL research and development team for E2O Communications. "This unique technology will allow E2O to supply LW VCSELs to cover all of the ITU defined CWDM and DWDM grid wavelengths for increased bandwidth in both the datacom and telecom markets."

"E2O is committed to bringing value to our customers with this superior LW VCSEL technology," said Dr. HC Lee, president and CEO for E2O Communications. "Our LW VCSEL is technically mature enough to replace DFB lasers in 10 Gigabit Ethernet applications to support installed base multimode fibers. It's also an ideal low-cost and high performance solution to support fiber channel applications up to 4.25 Gbps on a 10km single mode fiber."
