BSTRACT
In this article, we analyze the testing processes of optical communication systems and their fibre test
aspects. There is considered the meaning and functions of the software applications. Optical
communication systems have their equipment, fibres, and software applications. They have to work, in
coordination. Therefore testing of equipment and other parts is completed by software applications.

The growing importance of transmission systems
using optical as a physical carrier is resulting in
an increase in economic resources that
telecommunication providers are dedicating to
the corrective and preventive maintenance of
those systems and carriers. The essential
objective of such maintenance is to achieve the
highest quality and best economic output from
the said systems and carriers. Automatic and
centralized monitoring systems, unlike manual
operators, provide rational and exhaustive
control of the plant or designated elements
thereof. Existing automatic monitoring systems,
dedicated to optical fibre monitoring, are based
on the development of specific elements and the
availability of optical switches with a large
number of channels that, in conjunction with the
gradual reduction in the price of auxiliary passive
elements, make for flexible systems at very
competitive prices, with a high degree of
modularity. In addition, the possibility of the
system working in the fourth transmission
window extends monitoring not only to fibres
working in the second window but also to those
working in the third and even in both [6,8,10].
The optical fibre monitoring system used by
TelefUnica de Espana (for example) meets its
demands and specifications. This makes for a
system that is totally focused on monitoring and
management of the optical fibre plant, with
maximum output and efficiency in all its
functions. The system manages the reception of
alarms in the fibres when these are generated by
breaks or degradations. The system also conducts
a series of measurements aimed at identifying the
state of the fibres at any time. The system is
composed of all the optical fibre plant terminals
(OFPT) strategically distributed over the plant to
be
monitored.
These
terminals
collect
information on the state of the fibres and, by
comparing the actual state with a determined
threshold, generate an alarm situation when the
state optical fibre monitoring system (OFMS) &

information collected by the plant terminals
assigned to a specified monitoring area is sent to
the control centre responsible for the
maintenance and conservation of the area in
question. Referred to requires it. The information

System performance. Analyzed from the
operational point of view, the optical fibres
monitoring system described in this appendix has
the following functions:
•
Monitoring of vacant fibres as well as
fibres in service by means of reflecting o
metric techniques in the second, third and
fourth transmission windows.
•
Detection and location (using the
corresponding mathematical algorithm) of
degradations and breaks in the fibres.
•
Automatic execution of measurements in
the event of alarms in the line
transmission equipment (LTE).
•
Execution of measurements on request
from a higher hierarchy (remote control
centre, operation site).
•
Recording of singular points (splices,
manhole, etc.) that allow the events of the
trace to be associated with their
geographical location.
•
Assignment of vacant fibres to various
transmission systems with the purpose of
executing measurements in these fibres
when any alarm occurs in the LTE and in
regenerators that are not connected to the
fibres.
•
Recording of historical and reference
measurements enabling a provisional
evolution analysis.
