Laser Safety and ESD Protection
1,The laser safety level of MT04 series optical Tx modules is ClassⅢB (5mW~500mW). When using the Tx laser, the user has to avoid to exposure to the beam.
2, The MT04 series optical Tx modules have electrostatics sensitivity devices, so the user has to do a good job of ESD protection when using the modules.
Heat Dissipation Requirements：
In order to ensure proper performance, heat sinking and heat removal must be provided by the user to limit maximum temperature of the transmitter and receiver module. The bottom of the module is the preferred heat dissipation surface.
Mechanical (unit: mm)
Optical Transmitter
Note: When using the module, the bottom of the module needs to be fully cooled.
