InfiniBand/kuitu-kaapeli BlueOptics 00D5810-LE-BL 5 m QSFP

The BlueOptics 00D5810-LE-BL is a 5 m InfiniBand/fibre optic cable with QSFP connectors on both ends. Designed for short-range, high-speed interconnects in data centers and rack environments, this cable supports 40G data rates over a 5 meter distance and is compatible with hardware platforms that accept QSFP-to-QSFP direct attach connections. The construction follows MSA-compliant specifications for QSFP connectivity and is intended for reliable electrical twinax transmission when used as a passive direct attach cable.

Advantages

The cable provides a cost-effective, low-latency connection for short-distance links within and between adjacent racks. Its passive twinax design requires no active components in the cable itself, reducing power consumption and simplifying deployment. Built with industry-standard components and tested for compatibility with major hardware platforms, the cable is intended to deliver stable 40G performance for Ethernet, FCoE, Fibre Channel and InfiniBand applications at 5 m length.

Suitable for

• High-speed rack-to-rack connections in data centers
• Interconnects between switches, routers and storage systems supporting QSFP
• Short-range links for 40G Ethernet, FCoE, Fibre Channel and InfiniBand
• Environments where low latency and low power consumption are required

Key specifications

• Cable length: 5 metres
• Connector type: QSFP to QSFP (both ends)
• Nominal data rate: up to 40 Gbit/s over 5 m
• Cable type: passive twinax (copper) suitable for direct attach
• Wire gauge: 30 AWG
• MSA-compliant QSFP interface

How to use

Insert QSFP connectors into compatible QSFP ports on the devices to be linked, ensuring proper alignment and a secure mechanical connection. Use the cable for short-distance electrical interconnects up to 5 m and verify that the connected hardware supports passive DAC twinax cabling for the chosen protocol. After installation, check link status indicators on the devices and confirm negotiated speed and protocol operation through the device management interface.

Recommendations

For reliable operation, avoid tight bends and excessive mechanical stress on the cable; maintain recommended bend radius and route the cable within rack cable management paths. Use this cable only for short-distance links as specified and ensure connected equipment officially supports passive QSFP direct attach twinax solutions. Periodically inspect connectors for contamination and reseat if link issues occur.
