## Summary description

The BlueOptics JH698A-BL is a 3 m InfiniBand/fibre optic cable featuring QSFP connectors on both ends. It is designed for high-speed data transmission in data centers and networking environments. The male/male configuration ensures easy connectivity between devices, making it ideal for connecting switches, routers, and servers.

## Long description

The BlueOptics JH698A-BL is a 3 m InfiniBand/fibre optic direct attach cable with QSFP male connectors at both ends. It is designed for short-reach, high-speed interconnects in racks and between adjacent racks, supporting 40GBase-CR4 data rates over a twinax copper medium. The cable follows MSA-compliant QSFP form factor specifications and is suitable for connecting switches, routers, servers and storage systems that accept QSFP-to-QSFP direct attach links.
Advantages
This QSFP-to-QSFP cable provides a low-latency, low-power passive connection for 40 Gbit/s links across a 3 meter distance. Constructed from high-quality twinax copper and compliant components, it supports Ethernet, Fibre Channel, FCoE and InfiniBand protocols where a passive direct attach cable is permitted. The passive design eliminates active transceivers, reducing power consumption and simplifying installation while offering long service life when used within specified environments.
Suitable for
High-speed switch-to-switch links within racks or between adjacent racks
Server-to-switch and storage-to-switch interconnects supporting 40G
Data center applications requiring low latency and low power consumption
Environments that support passive QSFP direct attach twinax cables
Key specifications
Length: 3 meters
Connector type: QSFP male to QSFP male
Data rate support: up to 40 Gbit/s (40GBase-CR4 compliant)
Cable type: passive twinax copper (30 AWG)
MSA-compliant QSFP form factor
Typical applications: Ethernet, Fibre Channel, FCoE, InfiniBand
Low power passive operation (no active electronics in the cable)
How to use
Verify that both devices support passive QSFP-to-QSFP direct attach twinax cables and that the system firmware permits passive DACs. Align and insert the QSFP connectors into the corresponding QSFP ports on each device until the latch secures. Do not force the connector; ensure a firm, straight insertion. For removal, release the latch and pull the connector straight out. Route the cable to avoid sharp bends and mechanical stress; respect the manufacturer’s minimum bend radius and avoid contact with hot surfaces or moving hardware.
Usage recommendations
Use this 3 m passive QSFP twinax cable for short-distance high-throughput links inside racks or between neighboring racks, and confirm compatibility with your switch or server vendor before deployment to ensure support for passive DAC operation.
