Installation

1. Unpack

· Check the package for obvious damage.

· Take out the device from the package.

· Check the appearance of the equipment for damage caused by transportation.

· If any damage occurs, please informed the shipping company and local agency in written form.

· Keep the package and the insertion for future upgrades or repairs.

Note: When the device returns to the factory, any damage caused by not using the original packaging will be considered as the responsibility of user.

2. Assembly and Power Connections

1. Place the device in a 19-inch wide rack or equipment cabinet with 1.75-inch (approximately 4.5 cm) spacing between the upper and lower equipment.

2. According to the design requirements, our company’s maximum power 1550nmEDFA can work in the temperature range of 0 °C ~ 50 °C. An ambient temperature of 25 °C and humidity which is no more than 95% (non-condensing conditions) is recommended. If necessary, the equipment should maintain proper temperature and humidity within these limits. It is recommended that this equipment be operated in a low dust environment.

3. The device can be powered by AC or regulated DC. When the AC and DC power supplies are used, the AC power is the main power source.

The power requirements are as follows:

AC input 94-245 VAC, 50-60 Hz

DC input 36-60 VDC, floating

Power consumption up to 50 W

4. The DC input power to the device must be the SELV source specified in CAN/CSA C22.2, No. 950-95.

5. This device should have good grounding and the grounding resistance should be < 4Ω.

Note: Use a large size (#20 AWG, or larger) wire to connect the chassis ground stud to the grounded equipment rack before connecting the circuit. When using DC input power, the chassis must be grounded.

3.  Optical Port Connection

1. Clean all optical connectors before connecting the transmitter.

Cleaning steps:

Fiber Patch Cord Connecter

-  Remove the fiber connector dust cap and wipe the connector. Use a microscope (100X or 200X) to check the end of the connector for scratches or debris.

-  If there are no scratches or debris, the connector is clean and ready for use. If scratches or debris are found, repeat the fiber patch cord connector cleaning procedure.

Fiber optic connector on the rear panel of the transmitter

-  The connector can be cleaned with compressed air cleaning connecter due to the protection of plastic sleeve. Compressed air should meet the following requirements:

-  Use inert gas to achieve complete dust removal.

-  High precision filtration to achieve < 0.2 microns.

-  Recommended for use in optical systems.

-  Using compressed air that meets the above requirements. Uncover the dust cover of the plastic sleeve so that the nozzle of the compressed air container is approximately 6 feet away from the connector. Spray several times against the plastic sleeve so that the connector should be clean and ready for use.

Cautious: Handle the fiber carefully. When removing the fiber connector gasket,

do not operate the fiber beyond the tensile and bending radii defined in the specification.

-  If there is no compressed air, the transmitter's fiber optic connector can be cleaned with a 2.5mm cotton swab, or the connector gasket can be removed to directly clean the fiber optic connector inside.

-  To remove the connector gasket, unscrew the screws on the left and right sides of the gasket. Do not screw the bolt with plastic sleeve on the gasket.

-  Slowly remove the connector pads from the rear panel of the transmitter and then remove each fiber connector from the plastic sleeve.

-  Clean each connector by the method of cleaning the fiber patch cord connector.

2. Verify that the laser button switch on the front panel of the transmitter is in the off position.

3. Use two fiber patch cord, one connected to the output of the transmitter and the high-power fiber amplifier, and the other connected to the output of the High Power Optical Amplifier and an optical power meter.

.4 Use an optical power meter to ensure that the transmitter’s output optical power is within the rated range.

5 Turn on the transmitter's laser button switch and then turn on the High Power Optical Amplifier electronic switch.

Troubleshooting

High power optical software monitors system operation, provides short notes on warnings, and have the ability to correct most device state deviations. For example: system parameter drift, device error, laser aging, and temperature change. The PUMP laser will continue to operate when it issues a warning; the warning can be eliminated by continuous self-test of the equipment or restoration of the relevant system parameters to the normal range. Some serious alarms can be eliminated by turning the power off and on again. If the relevant parameters return to the normal range, the alarm will automatically disappear.

Most of the warnings are triggered when the error correction capability approaches or exceeds its capability range. In most cases, users cannot correct these statuses. State correction requires specialized equipment and facilities, and these statuses can only be corrected when returning to the original factory.

1. Warning Status

When the PUMP laser is in the warning state, the status LED will turn red and a brief description of the status will be displayed. Warnings generally do not stop the device, only show that the relevant parameters are slightly out of range. If the warning state is stopped, it means that the relevant parameters return to the allowed range and the display and LED will return to their normal state without user intervention. It should be emphasized that the problem indicated by the warning should not be ignored, and there may be lurking serious system failures.

2. Alarm Status

When the PUMP laser alarms, it usually stops working. The alarm may occur while a related parameter is outside its safe working range, or a situation has caused damage to the laser. Some alarms can generally be eliminated after several power switch operations. For alarms that users cannot exclude themselves, please contact our company immediately.

3. Failure prevention

Users can prevent many potential problems by paying attention to the following information:

1. Place the PUMP laser in an operating range where the ambient temperature is between 0 °C and 50 °C and other conditions meet the requirements. It is recommended to place the Optical Amplifier in a low dust environment.

2. Ensure that the rear panel fan and front panel socket holes are clear, and the rear panel fan is running.

3. Check that the voltage of power supply is within the specified standard and that all connections are correct.

4. Keep the fiber connector clean and reliable, and prevent light leakage from causing a decline in the output optical power.

Warning

1、The laser light source on this class 3B laser product emits invisible laser radiation.

2、Direct viewing the optical signal input interface within a short distance may pose an eye hazard.

3、Please do not clean the optical signal input interface during lighting.

4、Reliable grounding and should be protected by static ESD during operation.

5、Connect the optical fibers of all ports before power on.

6、 The optical connector cannot be plugged or unplugged while the machine is working.

7、The machine cannot move or shake while working.
