Description

■ ITU wavelengths available from

1528.77 nm —1610.06 nm

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:

■ SONET/SDH compatible up to OC-48/STM-16

■ Temperature tunable for precise wavelength

selection

■ Integrated optical isolator

■ High-performance, multiquantum well (MQW)

distributed-feedback (DFB) laser

■ 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.

■ Industry-standard, 14-pin butterfly package

■ Characterized at 2.488 Gbits/s (NRZ)

■ InGaAs, PIN photodetector back-facet monitor

■ Low threshold current

■ D2555-type: high-performance device designed for

very low dispersion; used in fiber spans exceeding

170 km (3000 ps/nm).

■ High-reliability, hermetic packaging

■ Excellent long-term wavelength stability can elimi-

nate the need for external wavelength locker

■ D2570-type: high-power, direct-modulated laser

eliminates the need for optical amplifiers in DWDM

many applications.

■ Qualified to meet the intent of Telcordia Technolo-

gies* 468
