Description
The LTBiS from Fibotec Fiberoptics GmbH is an advanced multi-channel laser diode drive system designed to meet the rigorous demands of laser diode testing. This state-of-the-art system is engineered with a modular design, allowing up to 10 laser diodes to be controlled independently within a single 19-inch instrument. This flexibility is further enhanced by the ability to combine multiple instruments, operated by a single PC, into a rack configuration. For those requiring a more compact setup, a half-width rack accommodating up to 4 plug-in units is available as an optional feature.
The LTBiS is specifically tailored for laser diode burn-in and life testing, ensuring reliability and performance over extended periods. The system comprises two main hardware components: the 19-inch mainframe, referred to as the master, and up to 10 plug-in units. Alternatively, a 9.5-inch wide master with up to 4 plug-in units can be utilized. The master unit is easily controlled via a serial interface, with a straightforward command structure that facilitates precise operation. An integrated external forward testing photodiode, connected through an external fiber loop, allows for seamless testing and monitoring, with both the photodiode and laser accessible via a front plate terminated by FC/APC.
The master control interface of the LTBiS is equipped with RS-232 connectivity, with an optional USB interface for enhanced versatility. The system is housed in a robust 19-inch rack, capable of accommodating up to 10 plug-in units, or a 9.5-inch rack for up to 4 units. The power supply is designed with redundancy in mind, featuring dual IEC-320 plugs supporting 110-230 V AC. Efficient cooling is ensured through a strategic airflow design, drawing air in from the bottom front side and expelling it from the back side. The backplane is engineered to accept the maximum number of plug-in units, ensuring scalability and adaptability to various testing requirements.
The LTBiS is built to operate under a range of environmental conditions, maintaining performance in non-condensing environments with temperatures ranging from +5°C to 50°C. The system's features include automatic recognition of plug-in units and separate control of each laser, supporting operation in ACC, APC modes, and PVI testing. The TEC setpoint is adjustable between -20° and 60°C, providing precise thermal management for optimal laser diode performance.
