J599 MT ruggedized fiber Connector



This J599/MT series of products is based on J599 series circular fiber optic connectors, using standard MT high-density fiber optic ferrules. The connectors are quickly connected with three-head threads and use five Key positioning, supporting blind insertion, anti-corrosion, and anti-vibration functions. The J599 MT connector is made of 316L stainless steel with high contact density and anti-electromagnetic shielding function. The fiber optic components are removable, which is convenient for on-site installation. The connector has low loss and high reliability; it has the characteristics of waterproof, dustproof, and corrosion resistance.



  • Comply with J599A (MIL-DTL-38999)III standard
  • Outer shells made from a variety of materials can meet a wide range of harsh environmental and electromagnetic shielding requirements.
  • Header Docking uses five-key positioning, achieving blind insertion and preventing mis-insertion.
  • Adopts a three-headed thread for quick connection and has an anti-loosening structure
  • Adopting standard 12-core or 24-core MT fiber optic contacts, it can achieve 12~96(12*N) way optical fiber precision docking
  • MT contacts can be optional with PC or APC



  • WiMAX and LTE Base Stations
  • Remote Radio Heads (RRH)
  • Industrial outdoor applications
  • Power Systems
  • Mining
  • Airborne communication
  • Marine telecommunication
