Optical Fiber Light Source Driver

Light up your application

The OFLS series is a universal driving platform for fiber optic diode sources of various types regardless of application. It enables you to control operational current and temperature of different kinds of LD or SLD modules for reaching desired performance. Thanks to high performance and stability this driver finds its application in various environments and fits any customer demands.

  • Compact lightweight box or OEM driving board
  • High stability and superior performance
  • Universal platform supporting various types of diodes

The light source driver can be delivered either in standard compact lightweight box version suitable for handheld operation and easy storage or OEM driving board version designed for further integration into customer’s systems.

Features & Benefits

  • Stackable modules to save space
  • The warm-up time in terms of seconds
  • Optional components for output isolation, depolarization, coupling, filtering, etc.

Programmable buttons

The compact module is equipped by 3 buttons with preset output power for fast switching. The default values are set to 100%, 50% and 10%. These values can be changed with the SW tool.

External cooling

The TOSA package diodes are mounted into external peltier elements to keep operational temperature stable.

Internal/external modulation

Optical power output can be modulated by internal or external source of modulation. The modulation type is 100% amplitude pulse.
