Description
The Direct Modulated Isolated DFB Laser Module
contains an internally cooled, InGaAs, MQW, distrib-
uted-feedback (DFB) laser designed for 1.5
µ
m appli-
cations. The following three direct-modulation DWDM
product families have been established to meet vari-
ous OC-48/STM-16 system applications:
s
ITU wavelengths available from
1528.77 nm —1610.06 nm
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
Industry-standard, 14-pin butterfly package
Characterized at 2.488 Gbits/s (NRZ)
InGaAs, PIN photodetector back-facet monitor
Low threshold current
High-reliability, hermetic packaging
Excellent long-term wavelength stability can elimi-
nate the need for external wavelength locker
Qualified to meet the intent of

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.

Is floating-point DSP the same speed as fixed-point?
For example, if 6713 is a floating-point DSP, is the calculation time of 12.01*13.03 the same as 12*13?The 674x series is a Fixed/Floating-point DSP. For such a DSP, what is the difference between flo...
