LHX-302-COC/COS 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
