Product Introduction

The 1550nm DFB 100KHz BTF Narrow Linewidth Laser is designed for high-precision applications that demand ultra-stable, narrowband light sources. Operating at a 1550nm wavelength, this laser features a <100KHz linewidth, >50mW output power. It is ideal for WDM (Wavelength Division Multiplexing) systems, fiber-optic sensing, and test equipment that require low linewidth and high spectral purity. When operating, this device emits a high-intensity laser beam. Do not look directly into the fiber end face; doing so may cause eye injury.

Lead time

It takes around 10-15 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

● 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).

● Verify the stability of the product's operating circuit to prevent damage caused by pulse currents.

● 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.

● When using the device, strictly adhere to the operating voltage and current ranges specified in the datasheet. Key parameters—including Ith (Threshold Current), Iop max (Maximum Operating Current), Vop max (Maximum Operating Voltage), and λc (Center Wavelength)—should be referenced specifically in the test report provided at the time of shipment.Note:Operation beyond the absolute maximum ratings may cause permanent damage to the device.

Quality Assurance and After-Sales Service

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.
