LT1300 Series Internal Modulation Optical Transmitter Instructions（V1.3）

Special Note: 

 This equipment is a professional and precise equipment. The installation and commissioning must be performed by professional and technical personnel. Read this manual carefully before operation to avoid damage to the equipment due to misoperation, or to cause accidental injury to the operator. 

 When the optical transmitter is working, there will be an invisible laser beam in the optical signal output adapter on the rear panel. The optical signal output port should be prevented from aligning with the human body, and the optical output port should not be directly viewed with the naked eye. Human’s eyes may be caused permanent damage! ! ! 

 Any operation on the output jumper should be done with the pump laser switched off. Do not insert or pull the output port, or the jumper and output power will be influenced. 

 When installing the fiber optic connector, the force should be appropriate, otherwise it may cause the ceramic tube in the adapter to crack. Once the ceramic tube is fragmented, the output optical power will be greatly reduced, and the optical fiber connector will rotate slightly, and the output optical power will change significantly. 

 Before the equipment is powered on, it should be confirmed that the grounding terminals of the chassis and the power socket have been reliably grounded (the grounding resistance should be < 4Ω) to prevent the static electricity from damaging the laser device and prevent the chassis from being electrified and causing damage to the human body. 

 In order to ensure long-term stable operation of the equipment, users are advised to configure dedicated AC power supply for the equipment in areas where the grid voltage is unstable or where the voltage waveform is poor. Conditional users can also configure uninterruptible power supply (UPS) systems. In areas where the ambient temperature changes too much or the room environment is poor (the ideal operating ambient temperature of the equipment is 25°C), it is recommended that the user configure a dedicated air conditioning system for the equipment to improve the working environment of the equipment.
