MINI EDFA Optical Amplifier 1550nm 4ports Output Power 16dBm Building Optical Fiber Equipment Used CATV FTTB Network

1. Descriptions

MINI EDFA 1550nm building optical amplifiers are mainly used in CATV FTTB network. With only 23mm thick aluminium alloy shell, it can be mounted in high-rise residence or in office buildings’ weak electrical box.

This machine adopts 5V power adapter, With five levels of voltage protection. Use safer and more convenient.

2. Features

Special instructions:The performance parameters of this manual according to the measuring method of GY/T 184-2002 < CATV system analog opticalfiberamplifier technical requirements and measuring method>, and tested in the following conditions.

Test condition: With standard optical fiber and standard optical receivercomposed the test link. Set 59 PAL-D analog TV channel signal at 550MHz frequency range under the specified link loss.

Transmit digital modulation signal at range of 550 MHz ~ 862MHz, the digital modulation signal level (in 8 MHz bandwidth) is 10dB lower than analog signal carrier level.

When the input optical power of optical receiver is -1dBm, measure the C/CTB, C/CSO and C/N.

VI. after-sales service

1. I promise: products are free warranty for 13 months (to paste the factory serial number on the side of the device is identified by the factory starting time of day), and lifelong maintenance. Due to user misuse or irresistible natural factors caused by equipment failure, we will only be responsible for the maintenance, material costs and charge the appropriate fee.

2.  If the device fails, you should immediately contact your local dealer, or call our customer service center.

3. Fault device requires action by professional technicians on-site, so as to avoid equipment damage.

4. Special Note: for devices that was to open the maintenance by the user, our company will not be free warranty, only to the warranty and reasonable maintenance costs and material costs will be charged.

Cleaning and maintenance method for fiber optic connector

And a lot of times, we will drop light power outlet misjudgments for optical equipment failure, the actual fiber optic connector may be caused by dust or dirt, pollution, just proper cleaning and maintenance of fiber optic connector, you can troubleshoot. Below introduce operation method of cleaning and maintenance of fiber optic connector.

1. power off the device, carefully unscrew the fibre on activities from the adapter connector

2. with texture good lens tissue or carefully with a degreasing alcohol cotton light connector cleaning; such as degreasing alcohol cotton cleaning, cleaning is complete, also 1-2 minutes, let dry alcohol flavor of the active connector surface

 3. cleaning out fiber optic connection socket, access optical power meter,measuring output optical power, to confirm that the fiber optic connector has been cleaned.

4. clean the fiber optic connector back to the adapter, should pay attention to appropriate, in order to avoid too much force lets the adapter internal ceramic pipe rupture.

5. fiber optic connector after cleaning, the output light power is not normal, you should remove the adapter, unscrew another connector to clean it inside the machine; such as cleaning after the optical power remains low, at which point adapter might be contaminated, cleaning with the adapter. (Note: use caution when you remove the adapter operation in order to avoid damages fibers inside the machine. ）

6. dedicated compressed air available for adapter cleaning or degreasing cleaning alcohol cotton section. With compressed air cleaning, compressed air nozzles of gas tank at the adapter of ceramic pipes, ceramic tubes blowing compressed air into clean; with fat alcohol cotton cleaning, carefully into the alcohol cotton ceramic pipe cleaning. Attention alcohol cotton into the direction of articles should always be consistent, otherwise may not be able to reach the ideal cleaning effect.

Pay special attention to

A. in the cleaning operation of fiber optic connector should be avoided with optical connection diagram on the human body or human eyes, so as to avoid causing wing damage on the human body or human eyes permanently burn!!!

B.  installing fiber optic connector, force should be appropriate, failure to do so may cause the adapter in the ceramic fragments. Ceramic Tubes once the fragmentation, the output light power will drop significantly, turning it slightly and fiber-optic connector, the output light power will be significantly changed.

C.  any operation on the fiber, without turning on the pump laser, or high power output causes the output fibre connector is burned out, thus giving rise to the output power is reduced.

Such as equipment changes lead to a section in this manual do not match, are subject to change without notice.
