1 / 12 page D2570, D2526, D2555 Wavelength-Selected Direct Modulated Isolated DFB Laser Module Data Sheet, Rev. 3 July 2001 The 1.5 µm D2570, D2526G, and D2555 Laser Modules are available in a 14-pin, hermetic, butterfly package. Features s ITU wavelengths available from 1528.77 nm —1610.06 nm s SONET/SDH compatible up to OC-48/STM-16 s Temperature tunable for precise wavelength selection s Integrated optical isolator s High-performance, multiquantum well (MQW) distributed-feedback (DFB) laser s Industry-standard, 14-pin butterfly package s Characterized at 2.488 Gbits/s (NRZ) s InGaAs, PIN photodetector back-facet monitor s Low threshold current s High-reliability, hermetic packaging s Excellent long-term wavelength stability can elimi- nate the need for external wavelength locker s Qualified to meet the intent of Telcordia Technolo- gies * 468 * Telcordia Technologies is a trademark of Telcordia Technologies, Inc. Applications s Three direct-modulated DWDM families available to meet a number of OC-48/STM-16 applications: — Extended reach (100 km) — Very long reach (170 km) —Metro DWDM — Digital video Product Codes Description The Direct Modulated Isolated DFB Laser Module contains an internally cooled, InGaAs, MQW, distrib- uted-feedback (DFB) laser designed for 1.5 µm appli- cations. The following three direct-modulation DWDM product families have been established to meet vari- ous OC-48/STM-16 system applications: s D2526-type: designed to be used in OC-48/ STM-16 (2.488 Gbits/s) for extended reach, dense WDM applications (1800 ps/nm). The wavelength of the laser can be temperature-tuned for precise wavelength selection by adjusting the temperature of the internal thermoelectric cooler. s D2555-type: high-performance device designed for very low dispersion; used in fiber spans exceeding 170 km (3000 ps/nm). s D2570-type: high-power, direct-modulated laser eliminates the need for optical amplifiers in DWDM many applications. Product Code Peak Power Dispersion Performance D2570H 10 mW 1800 ps/nm (100 km) D2526G 2 mW 1800 ps/nm (100 km) D2555G 2 mW 3000 ps/nm (170 km) |
