Operating Instructions

Safety and Operating Instructions

The light emitted by this device is invisible and hazardous to human eyes. Avoid direct viewing of the fiber connector while the device is in operation. When operating with the connector uncovered, appropriate laser safety goggles must be worn.

Absolute maximum ratings shall only be applied to the device for a short duration. Long-term exposure to maximum ratings or simultaneous exposure to multiple maximum ratings may cause device damage or reliability degradation. Operation beyond the device’s maximum ratings may result in equipment failure and potential safety hazards. A dedicated matched power supply must be adopted to ensure the maximum forward current is not exceeded.

Devices mounted on heat spreaders require a qualified heat sink. The device shall be fixed to the heat sink with 4 screws (fastened in a cross pattern with an initial torque of 0.075 N·m and a final torque of 0.15 N·m) or clamps. The flatness deviation of the heat sink surface shall be less than 0.05 mm. Indium foil or flexible thermal interface materials are recommended between the device base and the heat sink. Thermal grease is not recommended for this application.

Prevent optical back-reflection, which may degrade the device’s spectral performance and output power stability, and even cause catastrophic facet damage. An optical isolator is strongly recommended to suppress back-reflection.

Do not pull the optical fiber. Avoid bending the fiber with a bending radius less than 3 cm. The fiber end-face shall be fully protected against contamination and mechanical damage during installation. After removing the dust cap, clean the fiber end-face unidirectionally with lens cleaning wipes or cotton swabs moistened with isopropyl alcohol or ethanol. Operate the device only with clean optical fiber connectors.

ESD Protection

Electrostatic discharge is a primary cause of unexpected product failure. Strict ESD precautions must be implemented at all times. Maintain continuous ESD protection during installation, including the use of anti-static wristbands, grounded work surfaces, and standardized anti-static operating procedures.
