Structure & Polarity Configuration
Cable Construction
This product features a breakout cable structure: the trunk section is a 3.0mm round cable containing 12 tightly buffered multimode fibers. At the breakout point, it fans out into 6 individual 2.0mm duplex legs, each terminated with an LC duplex connector.
The trunk jacket uses flame-retardant LSZH material compliant with IEC 60332-1; breakout legs employ 900µm tight-buffered construction for flexibility and durability.
The MPO end features precision ceramic ferrule and stainless steel push-pull housing rated for 500+ mating cycles. Each LC leg is clearly numbered (1-6) for easy field identification and troubleshooting.
Polarity Configuration
This model provides Type B polarity by default, conforming to TIA-568 standards and optimized for 40G/100G QSFQ modules and parallel optics applications:
MPO Pin 1 corresponds to LC Port 1 Tx (transmit)
MPO Pin 2 corresponds to LC Port 1 Rx (receive)
Pattern continues to form 6 complete duplex pairs
Typical Applications: 40G SR4 to 4×10G SR breakout, 100G SR10 to multiple 10G connections
Type A and Type C polarities are available upon request. We provide complete polarity test charts and configuration guides to ensure seamless integration with existing network architectures.
Application Scenarios
Data Center Spine-Leaf Architecture
Spine layer uses 40G/100G QSFP aggregation switches, connecting through MPO-LC breakout cables to Leaf layer 10G SFP+ access switches for flexible network expansion and cost optimization
High-Density Server Rack Interconnects
Top-of-Rack (ToR) switch 40G uplink ports connect via MPO to patch panels, then through breakout cables to server 10G NICs; one MPO cable replaces 6 traditional LC-LC patch cords
Storage Area Network (SAN) Deployments
Connects fiber channel switches to storage array controllers, supporting multipath redundancy design to ensure high availability and low-latency access for mission-critical data
Enterprise Campus Backbone Upgrades
Deploy MPO trunks between buildings or floor distribution rooms, flexibly connecting to access equipment on different floors through MPO-LC breakout cables, simplifying cable management
Cloud Computing & Virtualization
Connects virtualization hosts to aggregation layer network equipment, meeting surging east-west traffic demands, supporting dynamic VM migration and rapid containerized application deployment
Factory Testing Process
Endface Geometry Inspection
3D interferometric inspection of connector endfaces checking 12 parameters including radius of curvature, apex offset, and fiber height to ensure compliance with IEC standard Zone A/B/C requirements
Optical Performance Verification
Calibrated light source and power meter testing of insertion loss and return loss at 850nm and 1300nm dual wavelengths, with automated data logging and PDF report generation
Mechanical Durability Testing
500-cycle mating tests on sample units to verify connector spring mechanism and latch reliability
