SUNNYVALE, Calif. -- K2 Optronics, Inc., a provider of optoelectronic components for the telecommunications industry, has introduced the EC48 Series of transmission lasers for metro, extended-reach, and long-haul telecom markets. These SONET/SDH-compliant, directly modulated DWDM lasers offer the industry's longest reach for the lowest cost per kilometer across the C band. These 2.5-Gbps lasers are available in two power options - 2mW and 5mW (peak). They are available in versions with 200-, 400-, and 650-kilometer reach and cover DWDM channels at 100-GHz spacing across the entire C-band. A 50-GHz version will be available in Q1, 2003. Furthermore, all EC48 Series lasers have exceptionally narrow dynamic spectral linewidth and center wavelength stability, eliminating the need for wavelength lockers. Evaluation samples are available today. "Featuring the combination of longest reach for lowest cost per kilometer, EC48 Series lasers will rapidly set the precedent for directly modulated metro and long haul applications up to 650 km," asserted Raj Kapany, president and CEO. "Furthermore, our technology allows us to cover the entire C-band with just two InP-based chips, enabling K2 Optronics to deliver wavelengths to our customers in a fraction of the time it takes to build a DFB or EA modulator-based laser."
