1792 ECCW Narrow Linewidth CW External Cavity Laser Diode Analog Lasers & Photodiodes BROADBAND The 1792 ECCW series external cavity laser is a cost effective solution for a coherent laser source. The laser is fabricated in a 14-pin hermetically sealed butterfly package that incorporates a bias tee circuit, an integrated thermoelectric cooler (TEC), a thermistor, and a back facet monitor photodiode. The 1792 ECCW provides substantially lower phase noise and a longer coherence length than other semiconductor lasers, including DFB lasers. The wavelength stability is assured by design, eliminating the need for wavelength lockers and complex feedback control circuits. Features Narrow linewidth, < 10 kHz available ITU wavelengths across the C-band 100 GHz channel spacing 10 mW minimum output power Pigtail Type Optical Power Linewidth Minimum (mW) Typical (mW) SMF 15 20 50 PMF 10 12 50 15 20 50 Industry standard, high reliability, hermetic 14-pin butterfly package Performance Highlights KHz See following pages for complete specifications and conditions. Excellent long-term wavelength stability eliminates the need for a wavelength locker Back-facet monitor Designed to meet Telcordia GR-468 qualification standard RoHS Compliant Absolute Maximum Ratings Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess of those given in the operational sections of the data sheet. Exposure to absolute maximum ratings for extended periods can adversely affect device reliability.
