Semiconductor laser diode Reliability aging test system


LHX-302-COC Laser Reliability and aging test system

The LHX-302 is an air-cooled, electrically heated, rack-mounted aging system that supports high-density, high-reliability laser for life testing, burn-in testing, and performance testing.

Product Feature

The LHX-302 laser reliability and aging test system provides:

  • Can test up to 1280 lasers at the same time
  • Up to 2A laser drive current per channel
  • Flexible and reliable hot swapping operation, simple capacity expansion
  • Can replace aging drawers for aging lasers that are in different packages
  • APC, ACC and LIV test modes
  • Aging drawer supports measurement for external and/or internal photodiodes
  • Integrated Reliability Sys Control Software
  • Real-time monitoring channel status and test data
  • Can export saved test data
  • Intuitive graphical interface for checking system and test status
  • Can still process saved data during power outages and power cuts
  • The control measurement module automatically saves at least 5 hours of aging data (calculated in 5 minutes/time) in the accident of network failure
