bedrijfsnieuws over Role of Hybrid Trunk Cables in Data Center Backbone Infrastructure

Backbone Connectivity Needs in Modern Data Centers

Data centers require high bandwidth, low latency, and high density backbone connections between racks, rows, and buildings. Using multi-fiber trunk cables with MPO connectors helps meet those needs by consolidating many fibers into fewer physical runs.

Simplification and Reduced Cable Volume

Instead of using many duplex fibers individually, a single trunk hybrid cable with FC or MPO connectors aggregates capacity. This reduces the number of cable trays required, improves airflow, and eases cable management.

High Speed Optics and Parallel Fiber Links

Protocols like 40G SR4, 100G SR4, and beyond use multiple parallel fiber lanes. Hybrid trunk cables with MPO ends facilitate these parallel links. From servers or switches with MPO ports, fiber lanes are properly allocated for transmit and receive channels.

Testing Integration in Data Center Environments

Test gear often has FC connectors. Hybrid trunk cables with FC on one end allow direct testing of backbone links without converters or adapters. This enhances testing accuracy, speeds up validation, and helps validate performance of backbone before deployment.

Scaling for Future Expansion

Data center growth is ongoing. As traffic demands increase, bandwidth requirements grow. Installing hybrid trunk cables with core counts that can support future transceivers avoids frequent rewiring. Hybrid designs offer flexibility to evolve gradually.

Environmental Considerations in Backbone Deployment

Cables in backbone infrastructure may be exposed to higher temperature, vibration or movement during maintenance. Hybrid trunk cables must be rugged, with good materials, secure jacket, and strain relief at connectors. Proper routing, air flow, and rack planning help maintain performance.
