Application Scenarios

Top-of-Rack to Structured Cabling Integration

Connects QSFP28/QSFP+ ports on TOR switches directly to LC-based structured cabling infrastructure, eliminating the need for separate cassettes or adapter panels in space-constrained environments while maintaining full 100G/40G performance.

High-Density Patch Panel Breakout

Interfaces between MPO-based high-density patch panels and individual server or storage device LC ports, enabling 12:1 or 24:1 density ratios at the backbone while providing familiar LC interfaces at the equipment layer.

Parallel Optics Distribution

Distributes parallel 100G SR4 or 40G SR4 signals from spine switches to multiple 25G or 10G access layer devices, supporting leaf-spine architectures and oversubscription ratios common in hyperscale deployments.

SWDM 100G Single-Fiber Applications

Leverages OM5's wideband capability to support emerging SWDM4 100GBASE-SR BiDi applications, where a single LC duplex can carry 100G using four wavelengths per fiber (850/880/910/940nm), dramatically reducing fiber count requirements.

Migration and Hybrid Networks

Enables gradual migration from 10G/25G LC-based infrastructure to 40G/100G MPO-based backbone, allowing coexistence of both connector types during transition periods without wholesale infrastructure replacement.

Factory Testing & Quality Assurance

3D Interferometric Endface Inspection

Every connector endface (MPO and LC) is inspected using automated 3D interferometry to verify geometry, scratch/defect analysis, and cleanliness per IEC 61300-3-35 standards, ensuring core alignment and minimal signal loss.

Insertion Loss & Return Loss Testing

100% of assemblies are tested at operational wavelengths (850nm for OM5) using calibrated reference-grade test equipment, with results documented and available in individual test reports.

Polarity & Continuity Verification

Automated fiber mapping systems verify correct polarity configuration and end-to-end continuity for all fiber positions, eliminating field connectivity issues.

Mechanical Durability Testing

Sample cables from each production batch undergo 500-cycle mating durability tests and tensile/bend stress testing to validate mechanical robustness.

Environmental Screening

Representative samples undergo temperature cycling (-40°C to +85°C) and humidity exposure (95% RH) to ensure long-term reliability across diverse operating environments
