Product information

Description

The BlueOptics X2121A-3M-N-BL InfiniBand fibre optic cable QSFP 3m Male/Male is a 3-metre high-speed connection solution designed for short-reach links in racks and adjacent rack rows. It provides QSFP-to-QSFP connectivity for 40G-class applications and is suitable for data centre interconnects and high-throughput networking equipment that support QSFP direct attach solutions. The cable is intended for reliable, low-latency data transmission and is built to comply with Multi-Source Agreement (MSA) mechanical and electrical interface requirements.

Advantages

The cable offers a compact, passive twinax/direct-attach design that enables low power consumption and low latency for short-distance links. It is manufactured using industry-standard components to ensure compatibility across major networking platforms and is tested for consistent operation. The construction aims for extended service life and high availability while providing a cost-effective alternative to active optical modules for short-reach 40G connections.

Suitable for

  • Server-to-switch or switch-to-switch connections within racks
  • Short-distance high-bandwidth links in data centres
  • InfiniBand, Ethernet (40GBase-CR4) and Fibre Channel applications up to 40 Gbps over 3 metres
  • Storage system interconnects and high-performance computing clusters

Key specifications

  • Connector type: QSFP to QSFP, male-to-male
  • Length: 3 metres
  • Maximum data rate supported: up to 40 Gbps (per cable, suitable for 40GBase-CR4 and InfiniBand use)
  • Cable type: passive direct attach / twinax copper (suitable for short-distance electrical signalling)
  • Gauge: 30 AWG conductors
  • MSA-compliant mechanical and electrical interface
  • Designed for low latency and low power consumption

How to use

Ensure both endpoints (switches, routers or servers) support passive QSFP direct attach or the stated 40GBase-CR4/InfiniBand interfaces. With equipment powered down or in accordance with your site’s hot-plug procedures, insert each QSFP connector into the corresponding QSFP port until it latches. Verify link status via the host or switch management interface and monitor the link for correct speed and error statistics. For best results, route the cable to avoid sharp bends and mechanical strain on connectors.

Usage recommendations

Use this 3 m passive QSFP direct attach cable for short-reach connections inside racks or between adjacent racks, and confirm compatibility with your hardware vendor’s supported passive DAC list. Avoid excessive bending radii, secure cables to prevent strain on ports, and follow ESD precautions when handling connectors.
