Build a Stable and Robust Optical Fiber Network

High quality tightly buffered cables protect the fiber core and increase the strength and durability of the fiber.

Low insertion loss

high plug‑cycle durability; stable performance (<0.2 dB variation); seamless fiber alignment for reliable interchangeability.

Color-Coded Cable Sheathing for Easy Identification

The sheath color of fiber optical patch cord is usually defined by the fiber type and may vary depending on the mode and performance level.

Standardized Production

Multiple processes, strict screening, quality assurance.

To ensure that the center of the optical fiber grinding offset, the surface of the optical fiber without defects, the size of the end curvature radius and other technologies meet the standard

Insertion/return loss detection
Insertion loss ≤0.3dB, return loss ≥30dB

End detection
End geometry test to ensure that the end curvature radius vertex offset, fiber height meets the standard
