Maintenance service

Why does the instrument need maintenance?


Regular cleaning and maintenance can extend the service life of the machine

Ensure that the machine is in use with low loss and high accuracy

No maintenance

The machine is not cleaned and maintained for a long time, and the loss is large during use and detection, and the accuracy is low

Affect the use of the machine, increase power consumption and shorten the service life of the machine

The fiber fusion splicer cleans the presser foot and V-groove to prevent one side of the fiber from tilting when the splice is aligned, and the splicing loss is high

When the OTDR is not in use for several weeks, remove the battery. And please recharge it when use it next time, which can effectively extend its life; when the optical connector is not in use, please cover with a protective cover to avoid affecting the test results

The optical power meter is calibrated regularly, and use with a light source can reduce loss and improve detection accuracy

If fusion splicer is not maintained and cleaned for a long time, resulting in poor splicing quality, high loss

If the OTDR is not maintained and cleaned for a long time, it is easy to damage the optical connector, which will affect the test result, cause large errors, and cause damage to the machine and shorten its service life.

Long-term unclean calibration of the optical power meter will easily cause damage to the laser ceramic core, affect the test results, and shorten the service life of the machine
