Safety and Operating Instructions

The light emitted by this device is invisible and harmful to human eyes. Avoid direct eye exposure to the fiber connector while the device is in operation. Proper laser safety goggles must be worn when operating with the connector open.

Absolute maximum ratings should only be applied to the device for short periods. Prolonged exposure to maximum ratings or exposure to multiple maximum ratings simultaneously may damage the device or impair its reliability. Operation beyond the absolute maximum ratings may result in device failure or safety hazards. A power supply suitable for the assembly must be used to ensure the maximum forward current is not exceeded.

Devices mounted on a heat radiator require an appropriate heat sink. The device must be installed on the heat sink using 4 screws (cross-tightened with an initial torque of 0.075 Nm and a final torque of 0.15 Nm) or a clamping mechanism. The flatness deviation of the heat sink surface must be less than 0.05 mm. The use of indium foil or a soft thermally conductive material as a thermal interface between the bottom of the package and the heat sink is recommended. Thermal grease is not suitable for this purpose.

Avoid back-reflection to the device. It may degrade the device performance in terms of spectral and power stability.It may also cause catastrophic facet damage. The use of an optical isolator to suppress back-reflection is strongly recommended.

Do not pull the fiber. Do not bend the fiber with a radius smaller than 3 cm. The fiber tip shall be protected against contamination or damage at all times during installation. After removing the dust cap from the fiber tip, carefully clean it by wiping in one direction with optical lens cleaning paper or a cotton swab moistened with isopropyl alcohol or ethanol. Operate the device only with clean fiber connectors.

ESD Protection – Electrostatic discharge is a major cause of unexpected product failure. Extreme caution shall be taken to prevent ESD. ESD protection must be maintained during device installation – use wrist straps, grounded work surfaces, and strict anti-static techniques when handling the product.
