## Summary description

The BlueOptics JL278A-BO is a 20 m InfiniBand fibre optic cable featuring QSFP28 connectors. It is designed for high-speed data transmission and reliable connectivity in data centers and networking environments. The male-to-male configuration ensures compatibility with various devices, making it an ideal choice for efficient data transfer.

## Long description

The BlueOptics JL278A-BO InfiniBand fibre optic cable 20 m QSFP28 Aqua is a 20‑metre active optical cable (AOC) with QSFP28 to QSFP28 connectors designed for 100G high‑speed links in data centre and networking environments. The cable implements 100GBASE‑SR4 multimode transmission with integrated transmitter and receiver modules on each end, supports Digital Diagnostics Monitoring (DDM/DOM) and follows MSA (QSFP28 AOC) mechanical and electrical specifications to ensure interoperability with compatible network hardware.
Advantages
This 20 m QSFP28 AOC provides high bandwidth and low latency for short‑reach 100G links while being immune to electromagnetic interference inherent to copper alternatives. Manufactured according to MSA guidelines and populated with high‑quality optical and electronic components, the cable is tested for compatibility with major vendor platforms and offers digital diagnostic capabilities for remote monitoring of voltage, temperature, transmit/receive power and laser bias current. The pre‑assembled AOC eliminates patching and connector cleaning steps, simplifying installation and reducing potential signal loss.
Suitable for
 100G interconnects between switches and leaf/spine fabrics in data centres
 High‑performance computing (HPC) and InfiniBand environments requiring QSFP28 endpoints
 Connections between routers, storage arrays and top‑of‑rack switches over multimode fibre
 Short‑reach optical links where predictable latency and immunity to EMI are required
Key specifications
 Length: 20 metres
 Connector type: QSFP28 to QSFP28 (male-to-male)
 Data rate: up to 100 Gbit/s (100GBASE‑SR4)
 Optical media: multimode fibre (AOC with integrated transceivers)
 Monitoring: Digital Diagnostics Monitoring / Digital Optical Monitoring (MSA SFF‑8472 compliant)
 Compliance: QSFP28 AOC MSA mechanical/electrical profile; CE and RoHS conformance stated by manufacturer
How to use
Connect each QSFP28 plug to the corresponding QSFP28 port on networking devices, ensuring the port supports 100GBASE‑SR4 AOCs and DDM if monitoring is required. No additional patch cords or transceivers are needed because the active modules are integrated into the cable ends. Handle the cable by the connector housings, avoid tight bends below the recommended bend radius, and route the cable to prevent mechanical strain on the connectors during operation.
Usage recommendations
Verify device compatibility and software/firmware support for third‑party AOCs in the target hardware. Use multimode fibre‑rated racks and cable management to maintain bend radii and airflow. If DDM values are required for monitoring, confirm the host system exposes the diagnostics information before deployment.
