Fiber optics once just meet the needs of high performance systems, but now it has widely spread in various types of networks. If you are familiar with Copper Network, then you will soon find that fiber is a kind of something completely different. Not only because of its installation process is quite different with copper wiring, and troubleshooting methods also have very big differences. Compared with copper wire, fiber optics is more fragile, so there will be some potential failures exist when use.
The Most Common Troubleshootings In Fiber Optics
Any network professionals who have done network troubleshooting are clear that this is a complex process. So know where to start looking for faults is very important. Here are some of the most common fiber failures and the possible factors cause these faults, the information will help users to predict the network faults with bases.
Fiber break is usually due to external physical extrusion or excessive bending;
Transmission power shortage;
The Optical fiber laying distance is too long may cause a loss of signal;
Connector damage may result a loss of signal;
Fiber Optic joints and connectors faults may cause a loss of signal;
The excessive use of fiber optical joints and connectors may cause a loss of signal;
Fiber patch panel or splice tra connection failure;
Generally speaking, if the connection is completely unreasonable, then it may be fiber breakage. But if the connection is intermittent, may be the following reasons:
Poor junction levels or multiple junction times cause serious optical attenuation;
The dust, scratches, fingerprints, humidity and other factors damage the connector;
The transmission power is too low;
Connector errors in the Fiber Distribution Cabinet.
Collecting the fault performance and the basic information of possible causes. Using any available means, the key of troubleshooting is to get valuable information by asking the right questions.
The following are some of the problems should be first asked.
If anyone had moved the fiber (dismantling or reconnect) or moved the PC recently?
Find out whether recently PC is disconnected or be moved is very important. If the fiber optical cable is disconnected from the PC, then it is likely that the cable simply has not been properly connected, or problems occur when reconnection, or the fiber may damage when disconnect.
Whether the device recently was moved?
Most copper network failures are caused by someone walking too fast to the original sticking wall table, or cleaners accidentally move the table to do vacuum cleaning. Moving the table without unplug the network cable, the cable is likely to be excessive dragged, or is held down by table or folded. If such action would damage to a copper wire, then you can imagine what consequences will be brought to the fiber, as it is made of glass.
The vast majority of users are not clear that Fibre Optic Cables will break in the situation of stepped on or bend too much.
