Product information

Description

The BlueOptics JH235A-BL QSFP InfiniBand 3m Black is a 3-meter high-speed direct attach cable featuring QSFP connectors on both ends for male-to-male connection. Designed for short-range data center links and high-performance computing setups, this passive twinax-style cable supports up to 40 Gbps data rates on compatible hardware and provides a compact, low-latency electrical connection in a durable black jacket.

Advantages

This cable offers a reliable, low-latency electrical link with QSFP-to-QSFP connectivity and a 3 m length suitable for rack and adjacent-rack connections. Its passive construction results in low power consumption and a simple, robust design that reduces potential points of failure. The cable’s black outer jacket provides a professional appearance and easy cable management in server rooms and networking racks.

Suitable for

  • Interconnecting switches, routers, and storage systems within racks or between adjacent racks
  • InfiniBand and Ethernet applications requiring up to 40 Gbps over short distances
  • High-performance computing clusters and data center top-of-rack links
  • Environments that prefer passive direct attach solutions for reduced power use and latency

Key specifications

  • Cable length: 3 m
  • Connector type: QSFP to QSFP (male/male)
  • Application: InfiniBand, Ethernet and related high-speed protocols up to 40 Gbps (on compatible equipment)
  • Construction: Passive direct attach twinax-style cable
  • Product colour: Black
  • Typical weight: 0.25 kg

How to use

Ensure both endpoints support passive QSFP direct attach cables and the required transmission protocol (e.g., 40GBase-CR4, InfiniBand) before installation. Power down or follow hot-plug procedures recommended by your hardware vendor, align the QSFP connectors with the ports and insert until the latch engages. Route the cable to avoid sharp bends and mechanical stress; maintain the 3 m length within rack layouts for optimal performance. If swapping cables, remove by releasing the connector latch and pulling straight out.

Usage recommendations

Verify compatibility with your hardware vendor’s documentation and, if available, test a sample in your environment. Avoid excessive bending radii and protect connectors from dust when not in use. For installations requiring active optics or longer reach, consider appropriate transceiver and fiber solutions instead of passive direct attach cables.
