D2587P881

Data Sheet, Rev. 2 July 2001 Wavelength-Selected High-Power D2587P-Type (with Wavelength Locker)/D2547P-Type Isolated DFB Laser Modules Applications s Telecommunications: — Dense WDM — SONET/SDH OC-192/STM-64 — Extended and ultralong reach — Undersea systems Digital video s Description The D2587P-Type DFB laser module is designed for use with an external lithium niobate modulator and also in applications where high power (20 mW) is required. The use of an internal wavelength locker greatly enhances long-term reliability and reduces chirp and mode dispersion when used in conjunction with LN modulators at OC-192 data rates. A companion device, the D2547P high-power DFB laser module, is also designed for use with a lithium niobate external modulator, but without the use of an internal wavelength locker. Featuring wavelength selection and locking capabilities, the D2587P Laser Module is ideally suited for use with external lithium niobate modulators, and in high-power (20 mW) applications. Features s High-performance, multiquantum-well (MQW), distributed-feedback (DFB) laser D2587P-Type is offered on 50 GHz ITU grid wavelengths ranging from 1528.77 nm— 1610.06 nm D2547P-Type is offered on 100 GHz ITU grid wavelengths ranging from 1528.77 nm— 1610.06 nm Polarization-maintaining fiber pigtail For use with lithium niobate modulators High optical power (20 mW, CW) Hermetic, 14-pin package s s s s s s Wavelength-Selected, High-Power D2587P-Type (with Wavelength Locker)/D254...
