MT-RJ Connector (‘MT’ ferrule, ‘R’egister ‘J’ack latch)

The MTRJ connector holds a pair of fibers in a monolithic ferrule made of a plastic composite.  The ferrule is held inside a plastic body that clips into a coupler with an intuitive push and click motion, much like the copper RJ-45 jack.  The fibers are aligned by the pair of metal guide pins in the end of the ferrule of a male connector, which join into guide pinholes on the female connector inside the coupler.  The MT-RJ connector is an example of a duplex small form factor connector.  Having the pair of fibers held by a monolithic ferrule makes it easy to maintain the polarity of connections, and renders the MT-RJ ideal for applications such as horizontal fiber runs in facility cabling.
