1. Summary of 1510nm DFB Butterfly Fiber Coupled Laser Diode

The 1510nm DFB Butterfly Fiber Coupled Laser Diode high performance DFB laser diode is fibre coupled with single mode optical fibre. CW output powers are wavelength dependent and lie between 2mW and 20mW. Provided in a standard 14-pin butterfly mount, these laser diodes have a built in monitor photodiode, Peltier effect thermoelectric cooler, thermistor, and optical isolator. The SMF-28 or PM optical output fibre can be terminated with SC/PC, FC/PC, SC/APC, or FC/APC connectors.

The 1510nm DFB Butterfly Fiber Coupled Laser Diode is bare laser diodes without driver and controller. Laser diode in this format are highly susceptible to damage from electrical signals, such as voltage transients, spikes, and static electricity. Therefore, it is important to use suitable power supplies and mounts. Details of compatible drivers, mounts and thermoelectric controllers are in the laser accessories section.
