How to Identify the Fiber Optic Link Problems ?
Fiber optic networks are designed for continuous operation. Often, fiber optic networks work to their optimum efficiency. However, fiber optic link problems are sometimes faced in the networks. These fiber optic link problems are difficult to identify due to the complexity of the fiber optics networks. However, to ensure the optimum performance of fiber optic networks, it is essential to identify and resolve the problem of fiber optic links. This post discusses, the method to identify the fiber optic link problems and a few tips to resolve the same.
Methods to Identify the Fiber Optic Link Problems
There are two methods of detecting the problems in a fiber optic link, namely, the application of a time-domain reflectometer and a fiber optics visual fault locator. Out of which, a visual fault locator is frequently utilized by the fiber optics industry experts. Let us discuss what a visual fault locator is and how to use it for fiber link fault detection.
An Overview of Fiber Optic Visual Fault Locator
A visual fault locator is a laser-powered pen-like device that is designed for locating the errors in a fiber link. It can be used to analyze the fiber network at locations like spliced points, connector linkage, and throughout the length of the fiber cable. It can be used in a continuous laser detection mode or flash mode, based on the type of analysis being performed.
The following steps are taken during the identification of fiber optic link problems with the visual fault locator.
The visual fault detector can only be used in on-field fiber optics solutions. Therefore, the first step is to test the transaction point by directing the laser pointer at the connecting location. The transaction point is where the connector is spliced to the cable. Identify the presence of external optical power, if any. If there is no external influence, test the splice connection. Check if the cable is incorrectly spliced, if not, check for the next location.
Glide the visual fault locator through the length of the fiber cable. However, experienced fiber-optic network testers can use a logical approach to locate a potential area of the fault. Otherwise, the cable must be tested thoroughly. Across the length, one must check for fiber cuts, loss of signal strength, etc.
If the loss of signal strength is identified at one location, the fiber must be tested for another 20 to 30 miles. If the signal break traces cannot be indicated with the fault locator, the use of a time-domain reflectometer may be required in extreme cases.
NOTE: One or more faults may be diagnosed in fiber optic networks, the fiber optic solutions must be customized based on the errors.
Tips to Resolve the Fiber Optic Link Problems
Fiber optic links commonly suffer problems like fiber cut, diminishing signal strength, and attenuation at spliced locations. To resolve such errors, the following tips may be helpful.
Use appropriate and high-quality fiber optic connectors, media converters, fiber optic switches, etc.
Opt for quality fiber splicing services in order to reduce attenuation losses.
In the case of fiber cuts, re-cladding or replacement of fiber cable may be required.
Source only high-quality fiber optics transmitters and receivers to sustain the signal strength for a longer duration. The transmitters must be tested for the quality of laser or LED signal emitters.
As suggested in the tips, high-quality fiber optics products must be utilized in fiber-optic networks. That is why you must buy from trusted suppliers like VERSITRON. The company supplies high-quality fiber optic cables, connectors, network switches, fiber optic media converters
, and so on.
