Product Introduction

This is a 1550nm DFB laser with a 14-pin butterfly package, built-in TEC, and thermistor. It features a stable wavelength, 10mW output power, a typical 40dB side mode suppression ratio, and low threshold current. Optional with SM/PM fiber, wide operating temperature, and high reliability, suitable for fiber communication, optical instruments, and fiber sensing. Please control the drive current and temperature strictly, and avoid overcurrent damage.

The international logistics might take 3-5 working days.

Operation Notes

● When operating, this device emits a high-intensity laser beam; do not look directly into the fiber end face, as doing so may cause eye injury.

● Optical fibers are fragile; do not use the fiber to pull the device. When inserting or removing a device from its socket, do not apply pressure to or pull on the sleeve located at the rear of the device housing. For devices equipped with connectors, ensure that both the device and the fiber connector are lifted simultaneously during installation or removal.

● Before powering up all components, first activate the cooler, and then proceed with incremental power-up steps to prevent chip overheating and overload.
