1550nm CATV ERBIUM-DOPED FIBER
AMPLIFIER


Our module light pumped laser and Erbium-Doped Fiber is used by the original binding compontfrom USA.
We have reliable optical light power output stabilizing circuit and laser electrical refrigerator temperature to control the circuit, guaranteed the complete machine optimum performance and the laser long life steady work..
The microprocessor software have laser condition monitor, digital display fault warning, network management and various function. Once the laser’s operational parameter deviate software establishes permission scope, it will close laser’s power automatically. The red light coruscate, prompt alarm and digitizing tablet will point out fault cause.
This machine adopts 5V power adapter, With five levels of voltage protection. Use safer and more convenient.

3.1 link test conditions
Special Note: equipment technical parameters given in this manual is a reference to GY/T 184-2002 the Jeep analog fiber amplifier test methods under the technical requirements and methods of measurement, measured and, under the following test conditions.
Test conditions: and standard fibre and standard light receiver composition test chain road, and in provides of chain road loss conditions Xia, in 550MHZ frequency range within configuration 59 a PAL-D simulation TV channel signal, in 550MHZ-862MHZ frequency range within transfer digital modulation signal, digital modulation signal of level (8MHZ bandwidth within) than simulation signal of carrier level low 10Db, light receiver entered power for -1dBm Shi, measurement carrier combination three order poor took than (C/CTB), and Carrier combo the second beat of the street (C/CSO) and carrier to noise ratio (C/N).

5.1 front panel description
1) power indicator: when the lamp is lit when the internal switching power supply.
2) input optical power led: input optical power greater than -15dBm the lamp is lit.
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.
