The SANTEC ​TSL-550 Type C O-band​ is a high-performance semiconductor laser designed for precision optical communication, sensing, and testing applications. Operating in the ​O-band (1260~1360nm)​​ wavelength range, this laser delivers exceptional spectral purity and long-term stability, making it ideal for fiber-optic communications, optical network testing, optical coherence tomography (OCT), and scientific research.

  1. High Stability & Reliability

    • Utilizes a ​single-mode distributed feedback (DFB) laser cavity​ to ensure narrow linewidth and low phase noise.
    • Equipped with ​precision temperature control (TEC)​​ and ​automatic power control (APC)​​ for stable output power and wavelength.
  2. Low Noise & High Spectral Purity

    • Ultra-narrow linewidth (<100kHz typical)​​ for high-resolution spectral analysis and coherent optical communication.
    • Side-mode suppression ratio (SMSR) >50dB, effectively suppressing multi-mode oscillation for superior signal quality.
  3. Wide Tuning Range & Precise Control

    • Wavelength-tunable (covering typical O-band wavelengths)​​ with support for external modulation or software control (e.g., SCPI commands).
    • High wavelength accuracy (±0.01nm)​, suitable for DWDM system testing and optical component characterization.
  4. Integrated Design

    • Compact temperature-controlled housing​ minimizes environmental thermal fluctuations, ensuring industrial-grade performance.
    • Standard fiber-optic output (FC/APC or SC/APC connector)​​ for compatibility with single-mode fiber systems.
