1550-1610 nm DFB ITU Butterfly Laser Diode
The DFBI series fiber-coupled laser diodes are designed with a GaAs quantum well structure integrated with a grating that matches the ITU grids. These diodes feature a built-in isolator for preventing back reflection induced emission instability and a photodiode for precise monitoring and feedback control of the laser’s output power. Housed in standard 14 pin packages, these diodes are pigtailed to a 1-meter long single-mode fiber terminated with an FC/APC connector. Each unit undergoes rigorous testing prior to shipment to ensure reliability. Additionally, we offer cost-effective, high-performance feedback control drivers that maintains constant and adjustable output power, along with an externally cooled mounting fixture to stabilize the output wavelength. It is available in benchtop, and module or driver kit for convenient integration.

Integration and compatibility
Use these checks to connect 1550-1610 nm DFB ITU Butterfly Laser Diode to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.
- Optical interface and fiber
- Fiber Type: SM28, PM1550 · Fiber Buffer: 0.9mm Tube
- Specify connector polish and fiber architecture together. FC/PC, FC/APC and SMA interfaces, and single-mode, multimode and polarization-maintaining fibers, impose different return-loss, mode-field and alignment requirements.
- Wavelength and loss budget
- Wavelength: 1550-1610 nm
- Check the Laser Diodes & Sources passband, insertion loss, return loss and power handling at the actual source wavelength; a nominal telecom-band label is not a substitute for the configured range.
