## Summary description

The BlueOptics JL282A-BL is a 1 m InfiniBand fibre optic cable featuring a QSFP28 connector and 4xSFP28 connectors. It is designed for high-speed data transmission in data centers and networking environments. With male/male connectors, this cable ensures reliable connectivity and performance for demanding applications.

## Long description

The BlueOptics JL282A-BL InfiniBand fibre optic cable is a 1 m direct attach cable with a QSFP28 connector to 4xSFP28 breakout configuration in a black jacket. Designed for short-reach high-speed links in racks and between adjacent racks, this MSA-compliant cable supports up to 100 Gbps aggregate throughput using four 25 Gbps lanes. The cable uses 26 AWG twinax construction and is intended for use in switches, routers, storage systems and other network devices that accept QSFP28 to 4xSFP28 direct attach connections.
Advantages
This passive QSFP28 to 4xSFP28 cable offers low power consumption and low latency for short-distance interconnects. Manufactured to MSA specifications, it is compatible with major hardware platforms that support the original HPE JL282A type cable and is tested for reliable electrical signalling on 1 m links. The robust twinax construction and quality components provide a long operational lifetime and consistent performance for data centre top-of-rack and adjacent-rack connections.
Suitable for
100GBase-CR4 and 4x25GBASE-CR short-reach rack interconnects
High-density switch-to-switch or switch-to-server links in data centres
InfiniBand and Ethernet environments requiring QSFP28 to 4xSFP28 breakout
Applications where low latency and low power passive DACs are preferred

How to use
Ensure both endpoints support passive QSFP28 to 4×SFP28 direct attach cables and the chosen transmission protocol. Power down or follow hot-plug procedures recommended by the device manufacturers if required, then insert the QSFP28 plug into the QSFP28 port and the SFP28 plugs into the corresponding SFP28 ports. Verify link status and negotiate speed according to the switch or host firmware. For best results, route the cable to avoid sharp bends and mechanical stress.
Usage recommendations
Use this 1 m BlueOptics QSFP28 to 4×SFP28 DAC for short-distance, high-bandwidth rack interconnects where low latency and low power consumption are priorities. Confirm device compatibility with QSFP28 passive DACs and test links in your environment prior to deployment.
