The CSRayzer RZSLD-1550-xx-xx-xx-14-HB Series is a high-performance 1550 nm Wide Band Superluminescent LED (SLED) designed for advanced photonic applications requiring broadband, stable, and high-power light sources.

With a typical ex-fiber optical output power of 10 mW and a broad 3 dB bandwidth of 85 nm, this device ensures consistent spectral coverage from 1510 nm to 1590 nm with minimal spectral modulation (<1 dB). Housed in a compact 14-pin BTF package, the module comes with either single-mode or polarization-maintaining fiber pigtails longer than 1 meter, making it versatile for integration into a wide range of systems.

Its excellent polarization extinction ratio (optional, PER > 15 dB) and high environmental stability further enhance its suitability for precision applications such as fiber optic gyroscopes, biomedical imaging, OCT systems, and optical test instrumentation. 

Equipped with an integrated thermoelectric cooler and thermistor, it offers precise temperature control and long-term reliability. CSRayzer’s RZSLD-1550 SLED provides a powerful, efficient, and flexible solution for next-generation optical systems.
