Key features

• Excellent Spectral Characteristics: Broad Spectrum: Wavelength range typically 1528nm-1563nm, covering the C-band, suitable for applications requiring broad spectrum (e.g., signal detection at different wavelengths in spectral analysis). High Spectral Flatness: Uses special optical processes and flattening techniques, achieving flatness around 1.5dB. Ensures relatively uniform power distribution across the C-band, guaranteeing consistency and accuracy for measurements/applications at different wavelengths.

• High Output Power: Offers high output power with options like 13dBm, 15dBm, 17dBm. Provides sufficient energy for optical signal transmission, meeting needs of long-haul fiber transmission and complex networks.

• Strong Stability: Incorporates global optical feedback control and PWM-based precise temperature control technologies, ensuring stability of output power and spectral shape. Reduces impact of temperature changes on performance for stable operation in various environments.

• Low Polarization Degree: Emits naturally unpolarized light with very low Degree of Polarization (DOP), typically ≤5%. Suitable for polarization-insensitive applications (e.g., certain fiber sensing measurements), reducing interference from polarization-related factors.

• Ease of Use: Provides communication interfaces (e.g., RS-232, LVTTL) and PC software for monitoring source status, enabling remote control and data acquisition, improving work efficiency.

• Compact Structure: WSEE laser products adopt a classic compact MSA (90*70*15mm) modular design, small size, easy integration into other systems, saving space. Suitable for applications with strict volume requirements.
