MTRJ Duplex fiber optic Connector
MT-RJ stands for Mechanical Transfer Registered Jack. An MTRJ
connector is a type of Duplex fiber optic Connector that has an
endpoint similar to the RJ-45 connector endpoint found in Ethernet
connections. MT-RJ t is very popular for small form factor devices
due to its small size. Housing two fibers and mating together with
locating pins on the plug, MTRJ connectors with the pins inserted
are called "male" connectors, the MTRJ connectors without the pins
are called "female" connectors.
MTRJ connectors are designed to snap into the Ethernet port of a
computer, modem, or wireless router and provide that computer or
network with extremely fast data transfer rates. MTRJ connectors
are usually designed for multi-mode optical fibers but can be used
for single mode optical fibers as well. MTRJ connectors are
approximately 2.45 mm x 4.4 mm in size and are standardized by the
International Electrotechnical Commission.
Industrial Standard:
MTRJ: TIA/EIA, FOCIS12, GR-326. IEC and JIS C5973.

How MTRJ Connectors Work
MTRJ connectors work in the same way that any fiber optic cable
does, with modes of light travelling parallel with the fiber and
their photons vibrating perpendicularly to the fiber. At its end,
each MTRJ connector has an RJ-45-like endpoint that is slightly
larger than a telephone jack and can fit into the Ethernet port on
any computer, modem, or wireless router.
MTRJ alignment pins are used when mating two MTRJ connectors. One
of the connectors should have two pins inserted in the two visible
holes in the face of the connector. As this connector is inserted
into a MTRJ adapter, these pins will mate with the two holes in the
opposing connector. MTRJ connectors with the pins inserted are
called "male" connectors, the MTRJ connectors without the pins are
called "female" connectors. Two pins should be ordered for each
adapter used.

connector has light projected through the fibers so you may see the
ends of the fibers in relation to the position of the two alignment
pins.
Applications
MTRJ connectors are used to provide fiber optic speeds to personal
computers, servers, commercial workstations, wireless routers,
modems, and other devices that have not already been equipped for
use with fiber optic cables. MTRJ connectors are, therefore, a type
of hybrid connector between a fiber optic cable and an Ethernet
cable.
Advantages
MTRJ connectors are advantageous because they allow users to take
advantage of fiber optic data transfer speeds without purchasing
any special equipment or installing specially designed fiber optic
systems. MTRJ connectors are fairly inexpensive and can be
connected to any Ethernet-enabled hardware in the same way that an
Ethernet cable can be.
