Educational Panel & Optical Instruments Optical Source in I/II Windows.
Using the panel  and the theoretical-experimental
handbooks of its equipment will enable to carry out a modular
theoretical-experimental course on optical fi bers and on the
electronic circuits and transmission systems using them.
It consists of a panel mounted on the vertical support and
includes optical instruments and different accessories.
In detail, the panel is provided with a silk-screen printed diagram
showing the functional blocks, the test and signaling points, all
connectors and the necessary sockets for the different circuit
topologies and for an easy and immediate understanding of the
operation of all its components.
Moreover professional optical instruments are used and also
troubleshooting operations can be carried out.
