Abstract

In Optical Loss Test Sets (OLTSs) or in bidirectional Optical Time Domain Reflectometers (OTDRs), data exchange between test instruments is made through the fiber under test. In the current configuration, data therefore cannot be exchanged while the test is being performed. A significant amount of time is wasted for data exchange and the operators cannot disconnect the test instruments to connect it to another fiber until data exchange is completed. Moreover, communication through the optical fiber under test is not available if the link under test is defective or if a test instrument is not connected to the right fiber. We propose to exchange data through an external link (via a Wi-Fi connection through routers connected to a dark fiber). A communication link is provided between two test instruments located at respective ends of an optical fiber link to be tested. It allows the two instruments to be in constant communication with one another throughout the service. It allows exchange of data between two test instruments via one or more dark fibers. A communication link between the two instruments is provided using a dark fiber. This allows the two instruments to be in constant communication with one another throughout the service. Data can therefore be exchanged while the test is being performed and after the instruments are disconnected from the fiber under test to be connected to another fiber to be tested. The fiber under test may still be used for continuity checks and synchronization. A consolidated report can be generated on one of the test instrument (master) while the test is conducted. Test status and results may also be displayed on both instruments for synchronization of test operations. The two test instruments can work together and can exchange data on the fiber under test to synchronize the measurements and exchange data for the bidirectional global measure of the link. The provided communication link between the test instruments may also be used exchange status indicators to indicate pass/fail results, a test is ongoing, a test is completed, etc. The ability of portable test instruments to exchange data over a network other that the link under test already exists. The combination of synchronizing through a fiber within the optical fiber cable under test and exchanging test data continuously during testing or while the test instruments are being disconnected to the fiber under test and connected to another is new.

Test data exchange between test instruments using a dark fiber communication router

Abstract

In Optical Loss Test Sets (OLTSs) or in bidirectional Optical Time Domain Reflectometers (OTDRs), data exchange between test instruments is made through the fiber under test. In the current configuration, data therefore cannot be exchanged while the test is being performed. A significant amount of time is wasted for data exchange and the operators cannot disconnect the test instruments to connect it to another fiber until data exchange is completed.

Moreover, communication through the optical fiber under test is not available if the link under test is defective or if a test instrument is not connected to the right fiber.

We propose to exchange data through an external link (via a Wi-Fi connection through routers connected to a dark fiber). A communication link is provided between two test instruments located at respective ends of an optical fiber link to be tested. It allows the two instruments to be in constant communication with one another throughout the service. It allows exchange of data between two test instruments via one or more dark fibers. A communication link between the two instruments is provided using a dark fiber. This allows the two instruments to be in constant communication with one another throughout the service.

Data can therefore be exchanged while the test is being performed and after the instruments are disconnected from the fiber under test to be connected to another fiber to be tested. The fiber under test may still be used for continuity checks and synchronization. A consolidated report can be generated on one of the test instrument (master) while the test is conducted. Test status and results may also be displayed on both instruments for synchronization of test operations. The two test instruments can work together and can exchange data on the fiber under test to synchronize the measurements and exchange data for the bidirectional global measure of the link.

The provided communication link between the test instruments may also be used exchange status indicators to indicate pass/fail results, a test is ongoing, a test is completed, etc.

The ability of portable test instruments to exchange data over a network other that the link under test already exists. The combination of synchronizing through a fiber within the optical fiber cable under test and exchanging test data continuously during testing or while the test instruments are being disconnected to the fiber under test and connected to another is new.

Description

Dark fiber - Wi-Fi network

A network is being setup between test instruments based on a dedicated network created through a dark fiber and Wi-Fi routers. This dedicated network is used for the test instruments to communicate and exchange test data. This allows the two instruments to be in constant communication with one another throughout the service. The two instruments may then behave as a single one.
