It provides reliable single-mode output with excellent long-term stability, making it ideal for precision testing and sensing applications.

Key Features

• Single-mode fiber output
• High stability and long-term reliability

Application Areas

• Optical testing and measurement
• Fiber-optic sensing systems
• Spectral analysis

Overview

The ASE Light Source (1.5 µm) uses erbium-doped fiber technology to generate a broadband, low-coherence output across the telecom band. It is designed for fiber sensing, DWDM component testing, metrology and laboratory platforms that require stable spectral power with minimal interference artifacts. Typical formats include benchtop and OEM module versions with standard fiber pigtails.

Main Features

• Broad spectral output across 1520–1600 nm (configurable)
• Low-coherence, low-ripple emission suitable for OCT and FBG interrogation
• Stable output power with long-term drift <0.05 dB (typical)
• SMF-28 or PM1550 fiber pigtail options; FC/APC termination available
• Benchtop and OEM module formats; compact and low-maintenance
• Integrated pump monitoring and over-temperature protection

Typical Technical Specifications

Applications

Common uses include distributed fiber sensing (FBG/DAS), optical component characterization (filters, WDM modules), OCT imaging sources, wavelength calibration and DWDM test benches. The broadband, low-coherence output makes this source especially valuable where speckle or interference fringes would otherwise degrade measurements.

Integration & Configuration Options

Available options include flattened spectral shaping, higher output power configurations, polarization-maintaining output fiber, custom pigtail lengths, and OEM mounting. Benchtop units include front-panel displays and local control; modules expose digital and analog control pins for seamless integration into automated test systems.

Safety & Handling

Follow IEC 60825 laser safety guidelines. Although ASE light is broadband and low-coherence, it still carries optical power that can be hazardous to eyes. Use proper fiber connectors, avoid bending beyond specified radii, keep connectors dust-free, and operate within specified temperature ranges.
