MT-RJ is an acronym for Mechanical Transfer Registered Jack. It is also sometimes referred to as a recommended connector for media termination. MT-RJ is a cable connector device based on the principle of fiber optic technology. These connectors are very small in size, making them a perfect and very popular choice for small form factor devices. MT-RJ connectors, which come from the family of MT connectors that can have up to 12 fibers, house two fibers that are combined with the help of the locating pins present in the plug. The main beauty of an MT-RJ connector is that it properly connects fiber cores mechanically so that all of the medium is sufficient to pass light through. There are various uses for these connectors based on various requirements. In terms of appearance, they usually look like a miniature 8P8C connector, but performance wise they differ substantially from each other.

With current advancements in the networking industry, the proprietary mechanical transfer connector has become a commonly used small form factor device due to its size, design and, of course, ease of use. The MT-RJ connector was initially introduced to the market to outshine the RJ45 connector and therefore has all the advantages of the RJ45 leaving behind its disadvantages. Like the RJ45 connector, the MT-RJ connector has 2 fibers that are integrated into a single design. The alignment is done with the help of the pins found on the connector. MT-RJ connectors are widely used in network applications. Their small design makes them very easy to connect and disconnect. Compared to its predecessor single fiber SC connector, the MT-RJ connector is half the size and offers higher density for cable management hardware, as well as offering a lower cost of termination. MT-RJ connectors are significantly lower in price compared to SC connectors, making them the preferred choice for network applications.

So depending on the end goal, like multimode or singlemode, you can choose what type of connector you need to connect different equipment. As stated above, the main difference is between the true dimensions of the cable and the mechanical coupling required to connect two or more ends. Today, in the age of miniature applications, size does matter, both smaller and to accommodate more and more connectors and cables, and here MT-RJ can be a good choice, as it can hold up to 12 fibers comfortably . There is hardly any network technician who does not need this wonderful connector with enough possibilities and applications. Compared to other applications, they are more preferred for applications where low termination costs and high density are required, regardless of whether it is electronics or even cable management hardware designs. So next time you need better performance and lower cost of installation and operation, feel free to use MT-RJ connectors.
