## Summary description

The BlueOptics JH234A-BL is a high-quality InfiniBand/fibre optic cable featuring QSFP connectors. Designed for reliable data transmission, it ensures optimal performance in data centers and networking environments. The Male/Male configuration allows for easy connectivity between devices, making it an ideal choice for high-speed applications.

## Long description

The BlueOptics JH234A-BL is a 1‑metre QSFP to QSFP direct attach cable designed for short-reach, high-speed links in data centers and rack environments. Implemented as a passive 40GBase‑CR4 twinax copper assembly with 30 AWG conductors and QSFP male connectors on both ends, the cable supports 40 Gbps electrical signalling for Ethernet, Fibre Channel and InfiniBand on short distances. Manufactured to MSA guidelines, it is intended as a compatible solution for systems that support the referenced 40GBase‑CR4 QSFP direct attach form factor.
Advantages
The cable provides a compact and low-latency physical connection for adjacent rack and intra-rack links while consuming negligible power because it is a passive twinax DAC. MSA-compliant mechanical and electrical characteristics ensure interoperability with major switches, routers and storage platforms that accept QSFP DACs. Use of quality cable materials and components supports predictable performance and long operational life in high-density network installations.
Suitable for
Short-reach 40G links between switches and aggregation devices
Server-to-switch and switch-to-switch connections within and between adjacent racks
High-performance computing and InfiniBand fabric interconnects operating at 40G
Fibre Channel and Ethernet links requiring QSFP/40G DAC connectivity
Key specifications
Connector type: QSFP male to QSFP male
Data rate supported: up to 40 Gbps
Length: 1 metre (approx.)
Cable type: passive twinax copper (DAC), 30 AWG conductors
Standards: QSFP MSA compatible, designed for 40GBase‑CR4 applications
Power consumption: passive (negligible additional power)
How to use
Install the QSFP BlueOptics JH234A-BL by inserting each QSFP male connector into the QSFP port of the devices to be linked, ensuring firm seating and latch engagement. Confirm that both devices support passive QSFP DACs and the 40GBase‑CR4 electrical interface before connecting. Once connected, verify link status and negotiated speed on the network equipment. For best results, route the cable without sharp bends and avoid mechanical stress at the connector ends.
Usage recommendations
Use this passive QSFP DAC for short, direct connections within racks or between adjacent racks where a 1‑m 40G link is required. Avoid using passive twinax DACs for longer spans or applications that explicitly require active optics. Maintain cable bend radius and secure cables to prevent accidental strain on QSFP connectors.
