● FAQ-1532nm DFB BTF Laser Diode

(1) What is BTF package?

--BTF (Butterfly) package is the standard 14-pin butterfly package, the most mainstream industrial- grade packaging format in the optoelectronics industry. This package integrates the laser chip, TEC temperature control, thermistor, and photodiode, offering excellent hermeticity and thermal management performance. There is no essential difference from standard butterfly packaging;“BTF”is commonly used as an abbreviation for“Butterfly”in product naming.

(2) What drive modes does this product support?

--1532nm DFB BTF Laser Diode supports continuous wave (CW) operation. A low-noise constant current source is recommended (threshold current approximately 5-20mA, operating current 50-90mA), along with a TEC controller for temperature stabilization (typically set at 25℃).

(3) Is sample testing available?

--Sample testing and small-volume trial production are supported. For bulk procurement, we offer volume pricing and tiered quotations.

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.

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

● 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.

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.
