ST Simplex or Duplex Patchcords

We provide ST patchcords with Ultra-polished (UPC), or other polish requirement. We guarantee every patchcord is well polished, meets / exceeds the industry standard.


Features :

  • Compliant with ANSI, Bellcore, TIA/EIA, IEC Standards
  • Metal housing with zirconia ferrule
  • Low Insertion Loss and High Return Loss
  • Pull-proof Design
  • 2.5mm high precision Japanese-made Ceramic Ferrules
  • Simplex or Duplex Configuration
  • Singlemode (9/125um) or Multimode (50/125um, 62.5/125um)

Quality Assurance:

Insertion loss and Return loss Insertion loss is the lost associated with a mated connector pair. Return loss is defined as the ratio of light reflected at the mated connector pair over the incident light. Both the Insertion loss and Return loss are given in logarithmic scale. All patchcords are 100% tested for insertion loss and return loss.
Geometric Requirements An advanced non-contact interferometric technique (DORC) is employed to measure the geometric parameters of the polished enface. The key parameters include radius of curvature, fiber height, apex offset, fiber and ferrule roughness. Geometric requirements are important to maintain the physical contact between mated connectors.
