The superiorities of usa green laser pointer are as follows

Alignment adapter ceramic tube with compressed air cleaning, compressed air tank nozzle, the compressed air blown into the ceramic tube cleaning; skim alcohol sliver cleaning, alcohol sliver careful penetration of the ceramic tube cleaning. Attention to the penetration direction of the sliver of alcohol should always be consistent, otherwise it may not be able to reach the desired cleaning effect. The process of using the optical transmitter, optical transmitter is abnormal, you should carefully analyze the reasons, do not be easily identified as the optical transmitter is damaged due; for problems that may arise in the work process of the optical transmitter, the paper be summarized as follows: equipment power, the front panel display and the lights are off. Switching power supply does not start properly, and equipment within the DC power supply is not normal.  green laser pointer    adopts the ID code encrypted transmission technology.
Check that the power supply is normal (AC160V ~ 250V), such as the supply voltage is normal, it may be a switching power supply module failure. Equipment connected to the power supply, front panel display shows the output optical power and laser status lights are normal, but measured the output optical power is low. Test jumpers poor quality. Optical active connector or adapter that may be contaminated. Adapter inside the ceramic tube may have been broken. The replacement of a good quality test jumpers. Cleaning contaminated live fiber optic connector or adapter. Specific methods of operation see "Optical fiber connector cleaning and maintenance." Replace the damaged adapter. After the opening of the network, the image of the light junction of the highlights of the obvious reticulate or large particles. The superiorities of    usa green laser pointer     are as follows.
Optical contact at the received optical power is too high, so that the optical receiver module output level is too high, and RF signal the intermodulation indicators of deterioration. Input optical transmitter RF signal is too high, beyond the device itself AGC control range, intermodulation index variation. The input RF signal of the optical transmitter intermodulation index itself is poor. Check the light contact at the received optical power, and make appropriate adjustments. Check the RF signal input level of the optical transmitter, and adjust to the input range of equipment requirements. (RF signal input level should be 72 ~ 88dBμV). Check the input RF signal of the optical transmitter intermodulation indicators and make appropriate adjustments. Network after the opening, the optical image of the contact at the apparent noise. Here will introduce the multi-function of   green laser pointer  .
The received optical power of the optical contact is not enough to cause the carrier to noise decreased. Input optical transmitter RF signal level is too low, enough so that the laser modulation. The system links the signal carrier to noise than the target is too low. By the method of cleaning optical fiber connector or adapter to restore the received optical power of the optical contact. Specific methods of operation see "Optical fiber connector cleaning and maintenance." Check the input RF signal level of the optical transmitter, and adjust to the equipment requirements of the input range (72 ~ 88dBμV). Spectrum analysis instrument inspection system link carrier to noise ratio, and adjusted if appropriate, to ensure the link signal carrier to noise ratio (C / N) is greater than 51dB.   green laser pointer  has the integrated functions.
