E2O Unveils 1310 nm-1550 nm Long-Wavelength VCSEL

E2O Communications unveiled an electrically pumped Long Wavelength Vertical Cavity Surface Emitting Laser (LW VCSEL) capable of generating wavelengths from 1270 nm to 1610 nm for LAN, metro, data communications and telecommunications applications. The VCSEL was developed 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 10km of single mode fiber, at 10.3 Gbps on 100m of 62.5 um core diameter multimode fiber, and at 3.125 Gbps on a 300m of 62.5 um core diameter multimode fiber. E20 said its device is technically mature enough to replace DFB lasers in 10 Gigabit Ethernet applications to support installed base multimode fibers.
