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.

An integral TEC provides stable thermal characteristics. cuitry to control the laser chip temperature. arrangement to maintain consistent laser output power. has a nominal 25 Ω impedance. shows the orientation of polarization in the fiber. module is being fully qualified for central office applications.
