LR-LINK 3m Active Optical Cable breakout from 100G QSFP28 to 4x25G SFP28 for data center networking.
High-density data center switches often face cabling congestion when connecting multiple 25G servers to a single 100G uplink port. Traditional copper solutions add weight and bulk, limiting airflow and increasing management complexity in crowded racks.
The LR-LINK QSFP28-4xSFP28-AOC-3m resolves this by converting one 103Gb/s QSFP28 interface into four independent 25.78Gb/s SFP28 lanes. Using OM3 multimode fiber with 850nm VCSEL transmitters, it delivers stable performance over 3 meters while maintaining a smaller diameter than DAC alternatives.
Ideal for merging 100G backbone infrastructure with 25G edge devices, this breakout cable supports seamless integration with existing host adapters and switches. Its hot-pluggable design and RoHS compliance make it a practical choice for scalable, energy-efficient network deployments.
Converts one 100G QSFP28 port into four 25G SFP28 ports for flexible network topology.
Uses 850nm VCSEL lasers and PIN receivers for reliable signal transmission over OM3 fiber.
Smaller diameter and lighter weight compared to traditional Direct Attach Copper (DAC) cables.
Supports hot-swapping of electrical interfaces for easy maintenance and upgrades.
