Foreword

This manual applies to EDFAB+PON 2U series fiber amplifier. It mainly

describes the performance characteristics, technical parameters, installation and

debugging, common troubleshooting, and other related content of the product. In

order to ensure that the equipment can be successfully installed and safely operated,

please read this manual carefully before installing and debugging the equipment. And

the installation and debugging sh ould be strictly according to the specified steps on

the manual to avoid unnecessary damage to equipment or accident harm to the

operator. Any questions, please contact with us in time.

Special Tips:

■ Er Yb Codoped Fiber Amplifier is h igh end professional equipment, and its

installation and debugging must be operated by special technician. Read this

manual carefully before operating to avoid damage to equipment caused by fault

operation or accident harm to the operator.

■ While the fiber amplifier is working, there is an invisible laser beam from the

optical output adapter on the front panel. Avoiding permanent harm to the body

and eye, the optical output should not aim at the human body and human should

not look directly at the optical output with the naked eye!

■ P lease make sure th at the ground terminal of the case and power outlet has been

reliably grounding before turning on the power (Grounding resistance should be

＜4Ω) to prevent the static damage the pump laser device and harm to human

because of case charged.

■ To ensure the equipment can work stable over a long time, in voltage unsteady or

poor voltage wave region, it´s recommend to the customer that he equips special

AC regulated power supply, or even AC uninterrupted power supply (UPS) system

for conditional users. In the region with large temperature variation environment

(The equipment's ideal work environment temperature is 25°C) or bad room

environment, it´s recommend to the customer that he equips special air-condition

system to improve the work environment.

8. Installation debugging

8.1 Unpack and Check

1. Ensure the package is not defaced. If it has any damage or water mark, please

contact local agency or carrier.

2. After unpacking, check equipments and accessories according to package list. Any

question, please contact local agency or our company.

3. If you think the equipment has been damaged, please don't electrify to avoid

worse damage. Please contact local agency or our company in time.

8.2 Instruments and tools

1. An optical power meter;

2. A digital multimeter;

3. A standard optical fiber test jumper (SC/APC);

4. Some absolute alcohol and medical cotton wool;

8.3 Installation steps

1. Before installing the equipment, please read the <User's manual> carefully and

install the equipment according to the <User's manual>. Note: For the man-made damage and other all consequence caused by error installation that not according to the <User's manual>, we will not be responsible and will not supply free warranty.

2. Take out the device from the box; fix it to the rack and reliably grounding. (The

grounding resistance must be < 4Ω).

3. Use the digital multimeter to check the supply voltage, make sure the supply

voltage comply with the requirements and the switch key is on the “OFF” position. Then connect the power supply.

4. Input the optical signal according to the d isplay message. Turn the switch key to

the “ON” position and observe the front panel LED status. After the pump working status indicator turn into green, the device is working normal. Then press the menu button on the front panel to check the working parameters.

5. Connect the optical power meter to the optical signal output end by the standard

optical fiber test jumper, then measure the optical output power. Affirm the measured optical output power and the displayed power are the same and have reached the nominal value. (Affirm the optical power meter is on 1550nm wavelength test position; the optical fiber test jumper is the matched one and on the connector surface has no pollution.) Remove the standard optical fiber test jumper and optical power meter; connect the device to the network. So far, the device has been completely installed and debugged.

9. Clean and maintenance method of the optical fiber active

connector

In many times, we consider the decline of the optical power as the equipment faults, but actually it may be caused by that the optical fiber connector was polluted by dust or dirt. Inspect the fiber connector, component, or bulkhead with a fiberscope. If the connector is dirty, clean it with a cleaning technique following these steps:

1. Turn off the device power supply and carefully pull off the optical fiber connector

from the adapter.

2. Wash carefully with good quality lens wiping paper and medical absorbent

alcohol cotton. If use the medical absorbent alcohol cotton, still need to wait 1~2 minutes after wash, let the connector surface dry in the air.

3. Cleaned optical connector should be connected to optical power meter to measure

optical output power to affirm whether it has been cleaned up.

4. When connect the cleaned optical connector back to adapter, should notice to

make force appropriate to avoid china tube in the adapter crack.

5. If the optical output power is not normal after cleaning, should pull off the

adapter and clean the other connector. If the optical power still low after cleaning, the adapter may be polluted, clean it. (Note: Be carefully when pull off the adapter to avoid hurting inside fiber.)

6. Use compressed air or degrease alcohol cotton to wash the adapter carefully.

When use compressed air, the muzzle aims at china tube of the adapter, clean the china tube with compressed air. When use degrease alcohol cotton, insert directions need be consistent, otherwise can’t reach a good clean effect.

Special notice: a. In the process o f clean the active optical fiber connector, you should avoid

direct shining at eye, which will cause permanence burn!!!!

b. Use proper energy to install the active optical connector, o r the ceramic tape

in the adaptor will lead to break. Once the ceramic tape is broken, the optical output power will decrease rapidly. And turn the active optical fiber

connector slightly, the optical output power changes obviously.

c. Please operate the optical fiber under the condition of shut off the pump

laser. Or the high output power will lead to burn the joint of the optical output fiber, which will cause the output power decrease.

10. After-sales Service Description

1. If the equipment fault is resulted from the u sers’ improperly operation or

unavoidable environment reasons, we will responsible maintenance but ask suitable material cost.

2. When the equipment breaks down, immediately contact MONDO PLAST.

3. The site maintenance of the fault equipment must be operated by professional

technicians to avoid worse damage. Special notice: If the equipment has been maintained by users, we will not responsible free maintenance. We will ask suitable maintenance cost and material cost.
