Fibotec Fiberoptics’ LTBiS laser diode life test and burn-in system is a multi-channel laser diode drive and TEC temperature control system that can be controlled through a digital electronic interface. The system design is modular, so that up to 10 laser diodes can be controlled independently within one 19-inch instrument. Several instruments operated by one PC can be combined in a rack. A half-width rack that accommodates 4 plug-in units is available as an option.

Applications for the LTBiS are laser diode burn-in and laser diode life test. The LTBiS consists of two hardware parts: The 19-inch mainframe (master) and up to 10 plug-in units (or a 9.5-inch wide master and up to 4 plug-in units). The master can be easily controlled by commands through the serial interface.

The external forward testing photodiode is integrated with the plug-in units and can be connected to the laser by an external fiber loop. Both, photodiode and laser, have a front plate access that is terminated by FC/APC.
