Single Mode Fiber(HI-1060) Coupling
Excellent Reliability，to be fixed fiber with GlassSolder
980nm pump laser module is the pump source of Erbium-DopedFiber Amplifier (EDFA). It needs higher output power and more strictreliability. In order to improve the product performance, we made someinnovation. Firstly, the higher power 980nm pump laser chip is selected.Secondly, low-temperature glass soldering technology is used in the process offiber lens fixing, chip soldering and other parts soldering. By all above thisinnovation, the stability and reliability is improved.

Donot put Laser transmission end (fiber cross section) to face toward your eye orskin. Active laser may burn your eye or skin.
AbsoluteMaximum Ratings are not allowd to violate, otherwise, the product may befailure.
Inthe mode of CW, do not load an over-limit drive current, and do not directlyturn off the electric power, otherwise, the product performance will bedegraded. The right way to start the drive power is as below. Drop the devicepower voltage to “zero” status before correctly connect the product accordingto the pin-connection guide. Then slowly increase the drive current by monitoringthe product output power.
Beforeinstallation,the product need to be smoothly fixed on the cooling radiator ofthe operation platform. The screw is M2.5. By this way, the bottom dissipationcan be guranteed, and the product can work for longer time.
Donot knock by hard object at the product cover and tail tube. Do not stronglypull or wring the fiber.
Inthe whole process of the product installation and working, system device andequipment need to have good earthing ( less than 2Ω of grounding resistanceis recommended). Staticcontrol wrist straps are required for operators.
