ASE 1550nm Broadband Light Sources
(SM, PM, 1528 - 1620nm, up to 10W)
Introduction
The ASE (Amplified Spontaneous Emission) light source series provides singlemode broadband emission with low coherence and randomized polarization, making it ideal for high-precision measurement applications. The design utilizes rare-earth-doped fibers pumped by a cooled laser source, enhancing longevity and reliability. Featuring precision feedback control, the unit ensures high stability.
The ASE 1550 is available in two wavelength bandwidth configurations: C-band (1528-1563 nm) and C+L band (1528–1615 nm). Agiltron offers both OEM modules with a driving PCB and plug-and-play benchtop units. Flat spectral output versions are available, integrating special filters in both C-band and C+L-Band. The ASE also functions as an excellent polarization light source with high and stable polarization extinction ratio.
These ASE light sources are widely used in telecom component testing, fiber Bragg grating (FBG) sensors, optical coherence tomography (OCT), fiber optic gyroscopes, gas sensing, fluorescence excitation, and optical component characterization.

Performance Data & Spectrums
Output Power Stability Description: Three plots show output power stability over 120 minutes for 20dBm, 23dBm, and 30dBm benchtop configurations. The power output remains stable with minimal fluctuation over time.
Typical Spectrums (without filter) Description: Two plots display the intensity spectrum of the light source without filters. The left plot covers the C-band (approx. 1520-1580 nm), and the right plot covers the C+L band (approx. 1540-1640 nm), showing broadband emission.
Typical Spectrums (With/Without Filter) Description: Two plots compare spectral density. The 'Without Filter' plot shows broadband emission across the C-band. The 'With Filter' plot shows a flatter spectral output across the C+L band, indicating the effect of integrated filters.
Dimensions
>20dBm Unit Description: A diagram illustrates the mechanical dimensions of the >20dBm unit, showing top and side views with key measurements (e.g., 160.0 mm length, 75.0 mm height, 258.0 mm depth). Front panel components like Display, T SET, TEMP, POWER, and Emission are labeled.
Mini Benchtop for 17dBm Description: Diagrams show the mechanical dimensions of the Mini Benchtop unit (17dBm), with front, top, and side views and measurements (e.g., 135.0 mm length, 118.0 mm height, 148 mm depth). Connector details are also shown.
Mechanical Dimensions (mm) Components Description: Detailed mechanical drawings show component layouts, PCB slot dimensions, high-power (>23dBm) and MSA package (20dBm) configurations, with specific measurements and connector pinouts.

* The low-cost/low-power configuration operates with a fixed output only and does not include a computer interface.
** Benchtop units feature USB/RS232 connectivity with a GUI for enhanced control. The component version includes pin connections, and an optional matching adapter PCB for USB/RS232 interface with a wall-pluggable power supply is available for easy control and power management ($278 each).
*** Standard connectors support up to 0.5W; exceeding this limit may damage the connector and, in turn, the laser core due to strong reflections. For high-power applications, Agiltron offers high-power connectors, which must be used in pairs.
Laser Safety
