## Long description

The BlueOptics 4Z57A85043-BL QSFP28 4x SFP28 InfiniBand 2m Black cable is a 2-metre male-to-male high-speed interconnect designed for use in data centers and high-performance computing environments. It combines a QSFP28 plug on one end with four SFP28 plugs on the other to support multi-lane InfiniBand and 25GbE connections over a single assembly. The cable is constructed for reliable signal integrity and long-term operation while presenting a black outer jacket for a discreet installation.
Advantages
This cable provides a compact way to break out a QSFP28 port into four SFP28 ports without active conversion, enabling high-bandwidth aggregation and flexible port utilization. Its 2 m length balances reach and manageability in rack and cabinet deployments. The male-to-male configuration ensures direct connectivity between compatible QSFP28 and SFP28 transceivers or ports, and the cable's build supports stable data transmission and reduced connection-related downtime.
Suitable for
 Data center uplinks and server interconnects
 High-performance computing clusters with InfiniBand networking
 Switch-to-switch or switch-to-server breakout connections
 Environments requiring 25GbE or 100GbE lane aggregation
Key specifications
 Cable length: 2 m
 Connector types: QSFP28 to 4 × SFP28
 Intended use: InfiniBand and compatible high-speed networking
 Colour: Black
 Weight: 0.25 kg
How to use
Install the QSFP28 end into a compatible QSFP28 port and insert each SFP28 connector into the corresponding SFP28 ports or transceivers. Ensure that connected devices are powered down or in a safe state if hot-plugging is not supported, and confirm link status via the host equipment. Route the cable to avoid tight bends and mechanical strain at the connector ends to maintain signal integrity.
Usage recommendations
Verify compatibility between the host hardware and the QSFP28-to-SFP28 breakout configuration before deployment. Maintain bend radius and secure cable management in racks to prevent attenuation or damage. Use the cable within typical data center temperature and humidity ranges and periodically inspect connectors for dust or debris.
