1250 - 1650nm SLD Broadband Light Source

• Ultra-Wide Spectral Coverage (1250–1650 nm)
  Delivers a broad, continuous spectrum across key telecom and sensing windows (O-, E-, S-, C-, and L-bands), enabling versatile use in fiber-optic sensing, component characterization, and medical imaging.
• Multiple Spectral Range Options
  Available standard configurations: 1250–1450 nm, 1450–1650 nm, 1250–1610 nm, and 1250–1650 nm, allowing users to optimize bandwidth and power for specific test or sensing requirements.
• High Spectral Power Density (≥ –25 dBm/nm)
  Provides strong, uniform output power across the selected band, ensuring high signal-to-noise ratio in measurement systems and enhanced sensitivity for interferometric and distributed sensors.
• Low Spectral Ripple (≤ 0.5 dB)
  Minimizes spectral fluctuations to deliver a smooth, flat output profile; ideal for accurate insertion loss, spectral response, and wavelength-dependent loss measurements in fiber-optic components.
• Excellent Output Stability
  Short-term stability ≤ ±0.02 dB (15 min) and long-term stability ≤ ±0.05 dB (8 hr) help maintain highly repeatable test results and stable system performance in laboratory and production environments.
• Low Degree of Polarization / Partially Polarized Output
  Reduces polarization-dependent effects in components under test and sensing systems, improving accuracy in devices sensitive to polarization such as AWGs, WDMs, and interferometric setups.
• Ultra-Low Polarization Extinction Ratio (PER ≤ 2 dB)
  Very low PER ensures quasi-unpolarized light, which is beneficial for characterization of polarization-dependent loss (PDL) and for minimizing polarization-induced measurement errors.
• Optimized for Fiber-Optic Sensing
  Ideal for FBG interrogation, optical coherence domain reflectometry (OCDR/OFDR), and distributed fiber sensing (DTS/DAS/DSS) systems that require broadband, stable, low-coherence sources.
• Suitable for Medical and Imaging Applications
  The 1250–1650 nm band supports biomedical imaging and spectroscopy, including near-infrared and tissue diagnostic systems that demand broad, smooth spectra and reliable performance.
• SMF-28 Fiber Output with FC/APC Connector
  Industry-standard single-mode SMF-28 fiber and FC/APC connector reduce back-reflection and simplify integration with existing fiber networks, test benches, and sensing setups.
• User-Friendly Benchtop Design
  Compact benchtop package (Code: B1) for easy placement on optical tables or in rack environments, with clear front-panel interface for quick setup and monitoring.
• Touchscreen and Remote Control
  Supports local touchscreen operation and remote control via RS232 serial communication (DB9 female port), enabling seamless integration into automated test systems and monitoring platforms.
• Wide AC Power Compatibility
  Operates from AC 100–240 V with low power consumption (≈ 30 W), suitable for global deployment in laboratories, production lines, and field environments.
• Robust Environmental Performance
  Designed for operation from –5 to +35 °C and 0–70% relative humidity, ensuring stable output in typical lab and light industrial conditions.

  Well-suited for testing WDM components, couplers, splitters, filters, AWGs, and passive/active fiber components where broadband, low-ripple light sources are required.
• Telecom-Grade Reliability
  Uses high-quality SLD technology and SMF-28 fiber widely adopted in telecom systems, delivering reliability and consistency expected for R&D, manufacturing, and network testing applications.
• Low-Coherence Broadband SLD Source
  SLD-based architecture provides low coherence length, reducing interference artifacts and speckle in imaging and measurement applications.
• Flexible Configuration and Customization
  Standard models cover 1250–1610 nm and full 1250–1650 nm bands; custom spectral ranges, power levels, fiber types, and connectors are available on request to match specific system requirements.
