ST SM SX Adapter

A fiber optic adapter or coupler is a special passive component designed to mate or connect two ends of a fiber optic cable with high precision. Fiber optic adapters mate two ends of different fibers optic connectors, achieving the conversion between different connectors FC, SC, ST,LC, MTRJ, MPO, E2000 and so on. They are widely used for Optical Distribution Frame (ODF),fiber optic communication device and equipment, with excellent performance, good stability. We can also call them Fiber optic Flange or Coupler. 

Fiber optic adapters are typically connecting cables with similiar connectors (SC to SC, LC to LC, etc.). Some adapters, called " hybrid", accept different types of connectors (ST to SC, LC to SC, etc.). When the connectors have differing ferrule sizes (1.25mm to 2.5mm), as found in LC to SC adapters, the adapters are significantly more expensive because of a more complicated design/manufacturing process.
