Optical networks and their components must be checked before, during, and after an installation.
The equipment's tasks are to:
-Validate transmissions between the transmission center and the customer's terminal to expected characteristics.
-Identify network problems, damage, or degradation.
-Perform physical tests and check for attenuation in installed components such as splices, connectors, breaks, bends, signal loss, among others.
Some of the tests performed on a network.
Optical power measurement: measurement is taken at the measurement point. For single-mode networks at 1310, 1490, 1550, and 1625 nm, and for multimode networks at 850 and 1300 nm.
Bidirectional optical loss measurement: measurement of optical loss in both directions of the network. This becomes a necessary test as line performance differs depending on the transmission direction.
Optical loss measurement: determined from the relationship between received power minus emitted power.
Link characterization: detection of events such as installed network elements or anomalies, and estimation of the total network length.
Losses, splices, splitters: measurement of losses for detected events in the network.
Traffic detection: detection of signal presence and direction in the fiber without disconnecting the line.
Fault localization: visual identification and localization of fiber bends or imperfections, as well as detection of deficiencies in connectors, especially those made in the field.
Video inspection: visual inspection of the physical condition and cleanliness of connectors.
In the following table, you can identify which measurement equipment allows you to perform the aforementioned tests.
