Fiber in the past was just to meet the needs of high-performance systems, but now it has appeared in various types of networks.
If you are very familiar with copper wire, then you will soon find a kind of fiber is something completely different. Not only because of the installation process and copper very different, and troubleshooting tools are also very different. Relative to the copper wire, the fiber is more fragile, so there will be some potential use of the fault.
The most common fiber failure.
Done troubleshooting any network professionals are aware this is a complex process. So know where to start looking for faults is very important. Here are some of the most common fiber failure, and possible factors produce these faults,glue stick this information will help users of network faults are educated guesses.
Fiber fracture is usually caused by physical compression or excessive bending force;
Transmission power is inadequate;
May result in the laying of long distance optical fiber signal loss;
Connector may cause damage to loss of signal;
Fiber optic connectors and connectors (connectors) failure may result in loss of signal;
Excessive use of fiber optic connectors and connectors may result in loss of signal;
Optical Fiber Distribution plate (patchpanel) or welding plate (splicetra) connection failure.
Generally speaking, if the connection is completely unreasonable, then it may be the fiber fracture. glue gun But if the connection is intermittent, there may be the following reasons:
Junction or a combination of poor production levels caused by excessive number of fiber attenuation serious;
Due to dust, fingerprints, scratches, humidity and other factors that damage the connector;
Transmission power is too low;
Errors in the wiring between the connectors.
Collection of information.
Whenever I was sent to a new network environment to deal with the problem, I want to do first thing is to collect performance and possible causes of failure of basic information. Using any available means, the key to troubleshooting by asking the right questions to obtain valuable information. The following gives some first question should be raised.
If anyone has recently been moving fiber (removal and re-connection), or moving too PC?
To find out whether PC has recently disconnected or moving very important. If you disconnect the fiber-optic cable from a PC, it is likely that cable simply has not been correctly connected, or reconnect the time is a problem, or when the fiber is disconnected received damage.
