BlueOptics 40GB-C05-QSFP-EN-BL InfiniBand-kuitu-kaapeli 5 m uros/uros

The BlueOptics 40GB-C05-QSFP-EN-BL InfiniBand fibre optic cable is a 5 m, QSFP-to-QSFP connection designed for high-bandwidth, low-latency links in data centres and high-performance computing environments. Built to support up to 40 Gbit/s over a short-distance interconnect, this cable provides a reliable physical layer for Ethernet, FCoE and InfiniBand applications when used with compatible QSFP ports. The male-to-male QSFP connectors and the 5 metre length make it suitable for rack-to-rack or intra-rack connections where consistent throughput and signal integrity are required.

Advantages

This fibre optic cable offers a compact QSFP-to-QSFP interface with support for 40 Gbit/s data rates and low latency transmission. The 5 m length balances reach and signal quality for typical data centre topologies, while the InfiniBand-compatible design ensures interoperability with systems that support QSFP-based high-speed links. The cable is manufactured to industry mechanical and optical standards to provide stable performance and predictable behaviour in professional networking environments.

Suitable for

• High-performance computing clusters and server interconnects
• Data centre switch-to-switch or switch-to-server links within racks
• Storage networking where low latency and high throughput are required
• InfiniBand and 40G Ethernet interconnects in short-reach deployments

Key specifications

• Cable type: InfiniBand-compatible fibre optic cable with QSFP connectors
• Length: 5 metres
• Connector type: QSFP male on both ends
• Maximum supported data rate: up to 40 Gbit/s (application dependent)
• Designed for short-reach, rack-level and adjacent-rack connections
• Low-latency physical interconnect suitable for Ethernet, FCoE and InfiniBand protocols

How to use

Install the cable by inserting each QSFP male connector into the corresponding QSFP port on networking equipment that supports QSFP-based 40 G links. Ensure devices are powered down or that hot-plug procedures recommended by the equipment manufacturer are followed if connecting live. Verify link status and negotiated speed in the host or switch management interface after connection. Use appropriate bend radius handling to avoid mechanical stress and keep optical interfaces clean to maintain signal quality.

Recommendations

For consistent performance, use the cable only with hardware that officially supports QSFP 40G links and observe manufacturer guidance for hot-plugging, port configuration and firmware compatibility. Store and handle the cable to avoid sharp bends and contamination of the connector endfaces; inspect and clean endfaces when needed to reduce insertion loss.
