An optical time domain reflectometer or OTDR for
Light loss in fiber cable is a serious issue because it can hamper or completely stop data transmission. With so many communications networks dependent on fiber optic cabling to transmit data, having a way to quickly diagnose problems means repairs can occur much more rapidly leading to less network downtime.
An OTDR works by injecting a series of optical pulses through the fiber which are reflected back to the injection point and measured for deviations or aberrations in the light wave. Based on the measurement of the deviation the trouble spot can usually be precisely located.
Some critics of OTDR systems point out that they can produce inaccurate measurements if two faults are located close to each other. There is also the potential issue of faulty measurements which can sometimes occur if the optical pulse has to travel a great distance. However with the proper training a technician can compensate for these issues and interpret the readings correctly.
All things considered when used correctly an optical technician will find an optical time domain reflectometer to be an invaluable instrument in the daily course of troubleshooting, repairing and maintaining fiber optic networks.

Hydraulic universal testing machines have very high accuracy requirements.
The hydraulic system is the power drive mechanism of the tensile testing machine.
The specific application of the electronic universal testing machine in the automobile manufacturing process: The electronic universal testing machine needs to be used for automobile parts.
Wave soldering refers to the molten solder (lead-tin alloy), sprayed by electric pump or electromagnetic pump into the solder wave required by the design, can also be formed by injecting nitrogen into the solder pool, so that it is pre-loaded The printed board of the component realizes the soft soldering of the mechanical and electrical connection between the solder end or the pin of the component and the pad of the printed board through the solder wave.
The frequency converter is a power control equipment that uses frequency conversion technology and microelectronics technology to control AC motors by changing the frequency of the motor's working power supply.
Electronic universal testing machine is a necessary equipment to control the quality of products.
The calibration operation of the electronic universal testing machine is still relatively unfamiliar to friends who use it for the first time.
Selective wave soldering defects and their prevention.
Testing machine, broadly speaking, is an instrument that verifies the quality or performance of a product or material according to the design requirements before it is put into use.
The tensile force is not an accurate value after being measured by the testing machine, and subsequent calculations are required to get the desired value.
