MTRJ stands for Mechanical Transfer Registered Jack. MTRJ connector is a small form factor (SFF) duplex connector with both fibers in a single polymer ferrule. MTRJ Connector uses pins for alignment and has male and female versions.


  • Compact Small Form Factor (SFF) allows two fibers to inhabit the space of one fiber
  • Increases port density required on a computer and networking-related hardware, panels, wall plates, and closets by 50%
  • Low insertion loss
  • Meets TIA-568A standards
  • RJ-45 latching mechanism, press-to-release design for ease-of-use


  • CATV
  • LAN & WAN
  • Telecommunication networks
  • PON (Passive Optical Network)
  • FTTX, FTTH (Fiber to the Home)
