　　标准1550nm扫描激光器 70nm光谱调谐

　　The SWL-1550 is specifically designed for FBG fiber sensor interrogation applications. The SWL-1550 contains a fast tunable laser source with control electronics. Driven by an electrical ramp voltage input, the SWL-1550 is a laser source that provides fast continuous wavelength sweeping. The SWL can come in either a rackmountable version or a module for OEM integration.

　　Depending on the user’s needs, the SWL can come in three models:

　　• SWL-1550W: Wide sweeping wavelength range of 90 nm that can monitor a larger number of FBG sensing.

　　• SWL-1550H: High output power of up to 300 mW, ideal for increasing the sensing distance and number of channels.

　　• SWL-1550S: Standard model that combines an output power of 20 mW and wavelength range of 70 nm to provide a cost-efficient solution.

　　Features

　　• Wide 90 nm sweeping range

　　• High power up to 300 mW

　　• Laser linewidth, FWHM, of 0.15 nm

　　• Optical Signal to Noise Ratio of 40 dB

　　• RS-232 interface for status monitoring

　　Applications

　　• FBG Sensor Interrogation

　　• Laboratory Testing and Measurement

　　• Fiber Optic Component Qualification

　　• Variable Wavelength Laser Source

　　Part Number: SWL-1550S
