The present invention relates to an optical switch board extension system for monitoring an optical line and, particularly, to a new concept technology which makes a system, for monitoring whether there is an abnormality in an optical line, increase a monitoring distance, at the same time conveniently extending a connection part of an optical cable as demanded by a user, thereby drastically enhancing a monitoring effect. A monitoring filter applied to a conventionally disclosed optical line monitoring system causes problems of reducing the monitoring distance because of an excessive loss caused by excessive accesses as three optical connectors access as a whole, and occupying an excessive area as well as having many spatial restrictions in installing a large number of monitoring filter boards. The present invention, to solve the problems, provides a technology for embedding the monitoring filter in an individual switch card and fusing optical core fiber of each monitoring filter, installed ...
