wall box. In most cases it is the critical part of the system that aligns the ferrule part of the connectors keeping the
fi bers in perfect alignment.
In the case of the MT-RJ and MPO the alignment is carried out by two small pins fi tted to one of the connectors, the
adapter is purely to support and lock the connectors together in the distribution panel or wall box.
The MPO connector and adapter use a different alignment mechanism to the traditional ceramic ferule connectors.
The alignment is performed through guide pins which are attached to the optical fi ber connector. The MPO adapter
is used to hold the connector in place and offer coarse alignment. The adapter offers a secure connection to hold
the connectors in place to prevent accidental disconnection.
