Introduction
The LS5000 Series Modules are DWDM DFB Laser Sources for the TXP platform . These laser source modules cover the 1528 – 1612nm wavelength range, on the 25GHz ITU grid, and provide 20mW optical power. The optical power can be tuned over 10dB, and the wavelength over ±1nm. These light source modules have been designed for excellent stability in power and wavelength, providing reliable measurement results for test setups characterizing BER link performance and EDFA parameters. The modules feature internal modulation capabilities for flexible coherence control, especially the triangular modulation format for efficient suppression of Stimulated Brillouin Scattering in fibers.

Stability, Accuracy and Dependability
The LS5000 Series modules are equipped with telecom rated DFB lasers with built-in TEC elements, optical isolators and low back-reflection (low return loss) fiber pigtails. Integrated into our precise drive and control circuit, the result is an extremely stable, low noise DWDM source. The modules offer a typical relative intensity noise (RIN) figure of -145dB/Hz and a stability of better than 0.005dB over 60 minutes.

Operation
A TXP chassis is required for the operation of the LS5000 Series modules . The modules are hot-pluggable; they can be inserted or removed during the operation of other modules. An intuitive graphical user interface (GUI) for the LS5000 Series modules is delivered with the TXP chassis, as well as drivers for LabVIEW™, LabWindows/CVI™, MSVC and Borland C.
