LC/UPC Mechanical Fiber Fast Connector



LC Fiber Optic Fast Connector also call LC Fast Fiber Connector or LC Quick Connector, designed for FTTH is a new generation of fiber connector used in assembly. It can provide Open flow and Pre-cast type of products, whose optical and mechanical specification meets the standard optical fiber connector. It is designed for high quality and high efficiency for installation; the structure of the crimping position is a unique design; and does not need gluing, polishing neither any consumables. Adopting fiber pre-installed structure, and convenient for field installation.



  • Precise mechanical dimensions
  • Low insertion loss, high return loss
  • Comply standard of IEC61754-4
  • Repeatable times is no less than 50 times;
  • Long life span design, more than 30 years.



  • Premise environments
  • Connections at the desk for LAN environments
  • Patch panels
  • Direct equipment termination
  • Fiber to the Subscriber (FTTH) applications
  • Repair/replacement requirements
  • Equipment test leads
