Laser Diodes & Sources
633nm Butterfly Laser Diode - 40mW
These laser diodes are fabricated in a hermetically sealed 14-pin butterfly package. They contain a monitor photodiode, thermoelectric cooler (TEC) and a thermistor to secure high-quality laser performance. Our laser products are Telcordia GR-468 qualified and in compliance with RoHS Directives. A matching driver is available in either a compact module or benchtop turn-key unit.

Integration and compatibility
Use these checks to connect 633nm Butterfly Laser Diode - 40mW 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: SM450, SM600, PM460, PM630 · Fiber Buffer: 900µm 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: 633nm
- 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.
