[ Laser technology... 3Q98 release date ] Lucent Technologies' laser module sets new benchmark for long-distance fiber optic transmission FOR RELEASE: MONDAY SEPTEMBER 22, 1997 EDINBURGH, SCOTLAND - Lucent Technologies' Microelectronics Group today announced an enhanced laser module that nearly doubles the transmission distance capability of lightwave communication systems without the use of regenerators. The device can transmit across spans of up to 1,000 kilometers, setting a new industry benchmark.... ...Lucent's previous-generation EMILM could transmit a signal 600 kilometers without signal regeneration. The E2550 electroabsorption-modulated isolated laser module (EMILM) is the latest in a family of cooled lasers intended for use in dense wavelength division multiplexing (DWDM) applications. DWDM is a technology that combines multiple optical signals on a single fiber - thereby increasing the capacity of existing fiber optic cables... ...As a result of the integrated design, the E2500 series offers. extremely low levels of chirp, which allows the laser module to triple the transmission capability of current laser configurations yielding greater distances with minimal signal degradation. Chirp, the shift of wavelengths produced when the modulator transmits digital information, can impair a transmitted signal.... ...Samples of the E2550 will be available within the first quarter of 1998 and volume production will be available by the third quarter of 1998. Volume pricing for the E2550 is $6200 each at quantities of 500 or more.... lucent.com Lucent Technologies demos record-breaking 100-channel optical amplifier with 'potential to revolutionize optical networking technology' FOR RELEASE: MONDAY JULY 21, 1997 lucent.com
