Product Introduction

The 1310nm DFB 100KHz BTF Narrow Linewidth Laser is a high-performance laser designed for applications in Lidar, wind radar, optical fiber sensing, and coherent communication. It features an output power up to 100mW, a 3dB bandwidth of less than 100kHz, and a low threshold current. Optional with SM/PM fiber, wide operating temperature, and high reliability. Please use under ESD protection and control the drive current & temperature strictly, and avoid overcurrent damage.

● FAQ

(1) 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

(2) What's the line width? Do you provide a normal line width LD?

--3dB line width is less than 100kHz. MHz-level LD is available.

(3) What's the power regulation range?

--10~100%

(4) Do you provide a protective fiber tube and fiber connector?

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

Lead time

It takes around 10 working days for production. (If there are some in stock, it will be faster shipped.)

The international logistics might take 3-5 working days.

Operation Notes

● 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.

Quality Assurance and After-Sales Service

● Warranty Period:

Free repair or replacement for non-human-induced defects within 1 year from purchase. Paid maintenance services available after 1 year.

● Exclusions from Free Warranty:

During the free warranty period, free repair or replacement services will be provided for faults caused by product quality issues. However, Box Optronics retains the right to refuse free repair services in the following cases within the warranty period:

(1) Damage caused by natural factors (e.g., lightning, dust) or environmental influences.

(2) Malfunctions due to improper operation by the user.

(3) Obvious physical damage caused by human error.

(4) Unauthorized disassembly, modification, or repair.

(5) Altered or incomplete warranty labels on the housing.

(6) Damage or loss during transportation.
