Product Introduction

1625nm 10mW DFB butterfly laser diode with multi-quantum well DFB structure and 14-pin butterfly package. It integrates TEC and thermistor, supports SMF-28e single-mode or polarization-maintaining fiber output, with a central wavelength of 1625nm and a typical output power 10mW. It features high SMSR and excellent spectral performance. Please control drive current, voltage, and fusion temperature, provide ESD and temperature protection, and do not exceed absolute maximum ratings.

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).

● 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.

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.
