LED Indicators Descriptions
Optical Tx
| Name | Descriptions |
|---|---|
| POWER | Power Supply Light; when the power is turned on, the green LED is light up and always on, and the LED does not light up when the power is turned off. |
| Light | Laser emitting Indicator: when the laser diode is emitting laser, the LED is light up in green and always on; when the laser diode is not enabled, the LED does not light up. |
| ALARM | Laser Abnormality Alarm Light: when the laser diode is abnormal, the red LED is light up and always on; when the laser is normal the LED does not light up. |
Laser Safety and ESD Protection
1,The laser safety level 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 and receiver module. The bottom of the module is the preferred heat dissipation surface.
Mechanical (unit: mm)
Note：The bottom of the Tx and Rx module is the preferred heat dissipation surface.
