Operating InstructionsSafety and Operating Instructions

The light emitted by this device is invisible and harmful to human eyes. Do not look directly at the fiber connector during operation. Appropriate laser safety goggles must be worn when operating with the connector uncovered.

Absolute maximum ratings may only be applied to the device for a short time. Long-term operation at or simultaneous exposure to multiple maximum ratings may cause device damage and reduce reliability. Operation beyond the maximum ratings may lead to device failure and safety risks. A matched power supply shall be used to ensure that the maximum forward current is not exceeded.

Devices mounted on heat spreaders require a proper heat sink. Secure the device to the heat sink with four screws (cross-tightened 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.

Avoid optical back-reflection, which may degrade spectral performance and power stability, and cause catastrophic facet damage. The use of an optical isolator is strongly recommended to suppress back-reflection.

Do not pull the optical fiber. Do not bend the fiber with a bending radius less than 3 cm. Protect the fiber end-face from contamination and damage during installation. After removing the dust cap, clean the fiber end-face in one direction with lens wipes or cotton swabs moistened with isopropyl alcohol or ethanol. Only operate the device with clean fiber connectors.

ESD Protection – Electrostatic discharge is a major cause of unexpected product failure. Strict ESD protection measures must be taken. Maintain ESD control during installation, including anti-static wristbands, grounded work surfaces and standardized anti-static operation procedures.
