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.

● This device is electrostatic-sensitive; therefore, strict adherence to anti-static protection measures is required during packaging, transportation, and usage. Additionally, precautions must be taken to prevent power supply surges, as failure to do so may result in permanent damage to the device (e.g., ensuring proper equipment grounding and wearing an anti-static wrist strap).

● 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.

● If the pins require soldering, the soldering temperature must not exceed 260°C, and the soldering time must not exceed 10 seconds. Particular attention must be paid to the following: during the soldering process, the device must be in an unpowered state, and the soldering iron must be properly grounded.

● During the power-up process, never apply a high current directly, as this risks damaging the chip. Instead, power up the device at a current level close to the chip's threshold, and then gradually increase the current in small increments until the desired level is reached.

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

FAQ

● Is it possible to change the wavelength by adjusting the current? What is the range?

--Yes. The current wavelength coefficient is 0.01 nm/mA, and the temperature wavelength coefficient is 0.1 nm/℃. The WL adjustable range is around ~center WL+/- 1 nm.

● What's the linewidth? Do you provide a narrow linewidth LD?

--3~5MHz. 1550nm Narrow linewidth LD (optional): less than 400kHz, 100kHz, 50kHz, 10kHz.

● What's the power regulation range?

--10~100%

● What's the wavelength tolerance?

--+/-3nm. Less is also optional.

● Do you provide a protective fiber tube and fiber connector?

--Yes. 900um loose tube and FC/APC, SC/APC, or other connectors are optional.
