The OS2 duplex SC to SC single-mode patch cord features a hybrid SC/SCduplex interface, distinguished by the following core characteristics:

1.Secure Push-Pull Latching
The SC connector's positive snap-in mechanism ensures stable, vibration-resistant connections—ideal for applications requiring reliable long-term installation. This makes the patch cord dependable in structured cabling environments.

2. Effortless Field Operation
Its push-pull design allows intuitive insertion and removal while maintaining ferrule alignment integrity. This user-friendly operation establishes it as a preferred choice for technicians in various installation settings.

3. Low Insertion Loss Performance
With precision ceramic ferrules and OS2 fiber, it ensures ≤0.3dB insertion loss and ≥40dB return loss—providing a stable foundation for single-mode connectivity in 10G/40G/100G optical links.

4. Clear Duplex Polarity
Color-coded connectors and distinct channel markings prevent connection errors, ensuring optimal reliability in data center and telecommunications networks.

1.Technical Standards & Compatibility

Compliant with industry fiber optic standards including 1000BASE-LX, 10GBASE-LR, and Gigabit Ethernet specifications.
Supports structured cabling systems, data center interconnects, and telecommunications infrastructure requirements.

2.Typical Application Scenarios

Data Center Structured Cabling: Direct connections between SC-port switches, patch panels, and core networking equipment in main distribution areas.
Telecommunications Infrastructure: Deployed in central offices, transmission rooms, and fiber distribution frames where push-pull SC interfaces ensure reliable connectivity.
Enterprise Network Backbones: Serves as standardized cabling for building backbone and horizontal distribution where SC connectors provide consistent performance across network segments.

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.

Fine grinding
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
