BlueOptics X66100-1-BL cavo InfiniBand/fibra ottica 1 m QSFP

The BlueOptics X66100-1-BL 1 m QSFP cable is a blue InfiniBand/fibre optic style direct-attach connection designed for short-reach, high-bandwidth links in data centres and rack environments. With QSFP connectors on both ends and a 1 metre length, this cable supports 40 Gbps class transmissions for linking switches, servers and storage hardware where low latency and reliable signal integrity are required. It is intended for installations that follow MSA physical and electrical guidelines for QSFP interconnects and is suitable as a direct-attach twinax solution for adjacent rack connections.

Advantages

This cable provides a compact, low-latency interconnect with predictable performance for high-density networking. As a passive direct-attach option it offers low power consumption and a simple design with a reduced failure rate compared with active optical transceivers. Constructed from industry-standard components and compliant with common QSFP and 40GBase-CR4 electrical characteristics, it delivers consistent throughput for Ethernet, FCoE, Fibre Channel and InfiniBand protocols up to 40 Gbps on a 1 m span.

Suitable for

• Short-reach connections between adjacent racks or within a single rack
• 40G links for top-of-rack switches to servers or storage
• High-performance computing clusters using InfiniBand or Ethernet fabrics
• Data centre environments requiring low-latency, high-density cabling

Key specifications

• Connector type: QSFP to QSFP (quad small form-factor pluggable)
• Length: 1 metre
• Support data rate: up to 40 Gbps
• Cable type: passive direct-attach twinax / short-reach copper assembly
• Wire gauge: 30 AWG
• Transmission protocols supported: Ethernet, FCoE, Fibre Channel, InfiniBand
• Construction: designed to meet MSA electrical and mechanical guidelines for QSFP interconnects

How to use

Install the BlueOptics X66100-1-BL by inserting the QSFP connector into the QSFP port on each device until the latch engages; ensure both ends are properly seated and the latch locks. Route the 1 m cable to avoid sharp bends and excessive strain; maintain minimum bend radius recommended for 30 AWG twinax assemblies. When connecting equipment, confirm that both devices support passive 40GBase-CR4 direct-attach twinax cables and that their QSFP ports are enabled and configured for the intended protocol and speed.

Recommendations

For reliable operation, verify firmware and hardware compatibility with passive QSFP direct-attach cables on your switches, servers or storage systems before deployment. Avoid using the cable beyond short-reach applications; for longer distances choose active optical modules or fibre optic transceivers matched to your platform.
