The Model 8008 Multi-Channel Modular Controller expands on the modular laser diode controller concept to meet the higher channel densities found in Dense WDM (wavelength division multiplexing) applications, 2-D VCSEL arrays, and multiple diode laser pumping. The eight bays accept either 8600C Combo Laser Diode Driver (LDD)/ Temperature Controller (TEC) modules or 8500D Dual Output LDD modules.
8600C Series Combo LDD/TEC modules are designed for use in communication applications and have an internal function generator for testing systems. The user only needs to program the frequency, I_max, and I_min to modulate the laser diode output. Both sinewave or squarewave (50% duty cycle) waveforms are available from 200 Hz–300 kHz. This range of frequencies meets today’s low frequency single-tone and high data rate test requirements for datacom and telecom.
For 2-D VCSEL arrays or high-density laser diode applications, where temperature control is not required for each individual laser diode, the 8500D modules allow the control of up to 16 lasers from a single Model 8008 mainframe.
The mainframe automatically detects which module is installed in each bay and displays the system configuration on a large LCD screen. A sophisticated processor provides enhanced system control and data collection capabilities.

GPIB/IEEE-488 and RS-232 interfaces are included with the Model 8008 for complete remote control and data collection. LabVIEW drivers are supplied with each 8008 mainframe. Automated testing and device evaluation are easily implemented using Newport’s extensive library of LabVIEW commands.
