Laser Safety and ESD Protection
1,The laser safety level of the optical Tx modules is ClassⅢB (5mW~500mW). When using the Tx laser,
the user has to avoid to exposure to the beam.
2, The optical Tx and Rx 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 module.
Mechanical (unit: mm)
Note: When using the module, the bottom of the module needs to be fully cooled.
Note ：Do not squeeze the M2.5 screws of the module to the optical component, otherwise it may cause the optical component to break.
