What are the best tips for testing the optical fiber cable?
The best tips for testing optical cables include knowing test techniques and principles. Testing requires some specialized equipment and thorough knowledge of its operation. It is also necessary to know good knowledge of networks, their construction, maintenance and possible problems. All devices should be tested before testing the optical fiber cable and safety glasses are recommended. In most cases, the installation and delivery of results is successful for the customer to consider the completed network task. The motto "Be prepared" is a necessary guide to testing the cable of optical fibers, because it is considered unprofessional, that it is necessary to call the manufacturer when it is work.
Before starting, collect the tools and perform reference bridge cables in both directions to ensure that they are all in good work. If the power meter can generate data messages, program them in advance for specific messages necessary for The Job. Collect the sizeRin the cables for all types of optical cables that will be tested and will prepare a table of all cables and connectors to be used for tasks before you go to the test operations in the field. The first point of view is to test all power connectors before we look at them, because some telecommunications and cable networks have a very high performance.
Check that the continuity is to be sure that the way of fibers from end to end through any connectors is sound and no fibers are broken. Use an optical fiber hitchhiking tool with a light -emitting diode (LED). Attach it to the cable and look down along the kernel length to see if there are any breaks in the light. If the light path is discovered, follow it back to the previous connector to see if there has been a real break that may require a section of section, noBo whether the fiber has broken or bent. Higher power tracery use lasers to find errors in connectors; In addition, a fiber optical microscope should be used to check the connectors. Medium magnification is best for viewing connectors at several angles to see if they are smooth and without scratches or whether there are any chips or fiber protruding from Ferrule.
The optical loss of power is the "relative" difference between the power that is connected in the component with the optical fiber cable and the power transmitted through it. This difference can be measured in connectors, connectors and cables. After installation, use a power meter or optical domain reflectometer (OTDR) to check the power level and receiver of each connector, cut and the whole system. Manuals of manufacturers will provide optimum measurement conversion factors and a list of maximum permissible losses. When testing, make sure the clutch has been made with a fusion montage at a bare minimum and has been handed over to the connection of the cellsÉholy, if not.
If high losses are found in the cable, turn it and test in the opposite direction; With this method it is possible to detect a bad connector in the network. The best tips for testing optical cables stresses the need to have good network documentation as a whole. It is necessary to know where all the cables go, how they were originally tested for the loss and length of each cable to have the basis for testing comparison. Insulate if there is a cable or device problem using a power meter to test the power output and receiver input and check the continuity in all optical cables using a laser indicator. If it is a cable problem, OTDR is a tool that can be used to find a fault and lift by renewal. Ethernet fibers require careful cleaning and inspection to function properly or cause cross contamination to neighboring connectors; Incorrect cleaning agents can destroy the Ethernet connector so use the microscope of optics fiber for conTrolling the end of the connector first.
