Shipping Instruction
The modules are shipped in tape & reeling packaging or Gel-boxes.
Note: No responsibility is assumed for the use of these products. The products canemit Class IV radiation and must be operated with extreme care. Avoid directly viewing the laser beam or exposure to specular reflections. Proper eyewear must be worn at all times when operating. VCSEL Chip in the modules are electrostatic-sensitive device and proper ESD protection is required forhandling.
