PARIS -- Alcatel Optronics (Paris: CGO et NASDAQ: ALAO), a world leader in opto-electronic components for telecommunications systems, today announced the launch of a new electro-absorption modulator laser integrating a wavelength locking function; the Alcatel 1945 LMM. This laser, with a precision controlled emitted wavelength, is the ideal product for 10 Gbit/s DWDM metropolitan transmission networks. This high-performance laser module also addresses the needs of DWDM systems in terms of space saving and cost reduction. To maximize the available bandwidth in optical transmission networks, WDM systems are increasing channel density. This results in a strong demand for narrower channel spacing. Therefore it is necessary to perfectly stabilize the emitted laser wavelength in all applications and for the entire lifetime of the transmission system. Previously, the function of an electro absorption modulator laser (EML) in metropolitan networks used discrete devices for wavelength stabilizing and monitoring. Now, Alcatel Optronics offers a highly integrated module incorporating transmission laser, modulation and emitted wavelength control. “This new laser demonstrates Alcatel Optronics’ advance in both monolithic and hybrid integration. This represents a real breakthrough since it provides a stable, compact and cost effective solution to increase channel density in metropolitan systems,” stated Philippe Brégi, chief operating officer of Alcatel Optronics. “With this highly integrated locked transmitter, we reinforce our position as a leading supplier of high density WDM solutions.” Alcatel SA
