Overview
Precision C-Band Tunable Light Source
This C-Band Tunable Wavelength Light Source utilizes a cooled external-cavity diode laser (ECDL) with thermally tuned etalon filters to ensure precise, single-mode operation. Designed for high-performance applications, it delivers low Relative Intensity Noise (RIN), a high Side-Mode Suppression Ratio (SMSR), and narrow linewidth for exceptional wavelength accuracy. It is an ideal solution for advanced fiber optic testing, including DWDM transmission and communication system verification.
