ST Patchcord

The ST connector type patchcords are offered for MM or SM applications with PC polishing method. Various boot color combinations allows to specify duplex straight or crossed interconnection cable and M5 (50/125 µm) or M6 (62.5/125 µm) fiber type.

  • Coupling nut radial track minimizes the rotation needed to mate the connector 
  • One piece body construction simplifies fields assembly
  • Single mode and multimode versions available 
  • Ceramic ferrules are configured for easy hand or machine "Ultra" Polishing 
  • Optional boot colors available 
  • Boot options for 2.0 mm and 900 micron breakout cable 
  • Universal dust cap (fits ST, SC, FC)
