The Newport 8510 – LDD Module is a laser diode driver engineered for precise current control and modulation of laser diodes up to 1000 mA. Designed as a plug-in module for Newport’s 8008 and 8016 modular mainframes, it delivers the high channel density required for DWDM and 2-D VCSEL array applications. The module accommodates both floating and common anode laser diode package styles, making it adaptable across diverse optical systems.

– Key Features
Internal function generator enables modulation testing with programmable frequency, Imax, and Imin parameters. Selectable waveforms—triangle, sine, and square (50% duty cycle)—operate from 200 Hz to 300 kHz, supporting both low-frequency single-tone characterization and high data rate validation. Remote operation via IEEE-488 (GPIB) and RS-232C interfaces enables automated test sequences and real-time data collection.
– Typical Applications
Ideal for telecommunications systems requiring dense wavelength division multiplexing and VCSEL array testing. Supports communication applications where precise modulation and current monitoring are critical.
– Compatibility & Integration
Installs directly into Newport Model 8008 or Model 8016 modular controller mainframes. The 8510D variant is specified for 8016 or 9016 mainframes. Configurable outputs support both floating and common anode laser diode architectures.
