Green laser pointer has the microphone sound amplification functions

In the region of ambient temperature change is too big or the room environment is poor (the ideal working environment is 25 ° C), necessary for the device is equipped with a dedicated air-conditioning equipment to improve the working environment of the device. Turn the machine off, adjust the front panel Status button to view the equipment operating parameters confirm that the device has entered the normal working condition. The optical signal output optical power meter is connected to the optical transmitter with a standard fiber test jumper, measuring equipment output optical power, and confirm the value of the output optical power and front panel display, and has reached the standard value; in the measurement The optical power should recognize the power meter at the 1310nm wavelength measurement file, to confirm the standard test jumper fiber test jumper for the match.   green laser pointer   owns the remote control function.
Activities of joint surface pollution-free. (In the work of the optical transmitter, located within the fiber optic adapter panel not visible laser beam output, the optical signal should be avoided to align the body, but not with the naked eye to look directly at the light output, so as not to cause permanent body, the human eye injury). Signal Level Meter or spectrum analyzer to measure the RF input signal level to confirm the input RF signal to meet the input requirements of the optical transmitter (the manufacturers product requirements, please refer to the manual), the RF signal is connected to the RF input of the optical transmitter . According to the actual situation of the equipment, set a good control of AGC and MGC state.   green laser pointer   has the microphone sound amplification functions.
Again measuring the optical output power, verify that the optical output power, removed the standard fiber test jumper and power meter, access network equipment, thus, the equipment is installed. Optical fiber connector is installed, the force should be appropriate, or may cause the adapter ceramic tube fragmentation, fragmentation ceramic tube output optical power will be greatly decreased, and fiber optic connectors turn a little, the output optical power will be more apparent the changes. Maintenance of the optical transmitter. In many cases, we will decline in the optical receiver output optical power level to reduce false-ray equipment failure, the actual optical fiber connector is dust or dirt contamination caused by only the optical fiber connector for proper cleaning and maintenance, to troubleshooting.    usa green laser pointer   works under the international standard of 2.4 G ISM wave band.
The following outlines the optical fiber connector cleaning and maintenance methods of operation. Turn off the power of the optical transmitter, carefully unscrew the adapter optical fiber connector is strictly prohibited with the optical fiber connector to align the human body or the human eye, so as not to cause harm to humans. The texture of a good rub carefully cleaning the lens paper or medical cotton wool dipped in absolute alcohol; with cotton wool dipped in absolute alcohol cleaning, after cleaning, you need to wait for 2 minutes, so that the active connection to the head surface to dry. Will be cleaning the fiber optic connector access power meter, measure the output optical power, and to confirm that the optical fiber connector has been cleaned. The audio modulation of   green laser pointer   is digital.
