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:

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.
D2555-type: high-performance device designed for
very low dispersion; used in fiber spans exceeding
170 km (3000 ps/nm).
D2570-type: high-power, direct-modulated laser
eliminates the need for optical amplifiers in DWDM
many applications.
