Fiber Cable Connectors in the Data Center: The MT-RJ (Mechanical Transfer Registered Jack)

The MT-RJ (Mechanical Transfer Registered Jack) was developed by Amp and Corning, but based on specifications from NTT.

About the MT-RJ

Two fibers are included in one connector that looks a lot like an RJ45. That’s where the last part of the name came from. Alignment pins are used to mate the connectors. MT-RJ’s come in two versions, with mating pins (male) and without (female). Though small, allowing for greater density, the MT-RJ has not taken off like the LC due to poor performance characteristics across the board.
