Cavo InfiniBand CBO MA-CBL-40G-50CM-BL QSFP 0,5 m

CBO InfiniBand cable MA-CBL-40G-50CM-BL QSFP 0.5 m is a 0.5 metre copper interconnect with QSFP connectivity designed for short-reach high-speed links. The cable provides a 40 Gbit/s aggregate data throughput and a compact 0.5 m length suited for rack- and chassis-level connections. It is intended for reliable, low-latency links between switches, servers and storage within data centre racks and network equipment enclosures.

Advantages

The QSFP copper design offers a simple, cost-efficient option for short-distance high-bandwidth interconnects without the need for transceivers. Its 0.5 m length reduces cable clutter and improves airflow in dense rack environments. Built for InfiniBand topologies, the cable delivers low latency and stable transmission characteristics for clustered compute and storage infrastructures.

Suitable for

• Short-reach connections between switches in a rack
• Server-to-switch links within the same chassis or rack
• High-performance compute clusters and storage arrays requiring InfiniBand links
• Environments where low latency and compact cabling are required

Key specifications

• Connector type: QSFP (Quad Small Form-factor Pluggable)
• Data rate: up to 40 Gbit/s aggregate
• Length: 0.5 m (short-reach copper link)
• Cable medium: copper
• Intended use: InfiniBand high-speed interconnects for rack/chassis-level links

How to use

Connect one QSFP end to the host port on a switch, server or HBA and the other QSFP end to the corresponding remote port. Ensure both ports support the same InfiniBand speed and QSFP interface. Route the cable within the rack to avoid sharp bends and to maintain proper airflow, keeping the length appropriate for the planned connection. No external transceivers or power are required for standard QSFP copper links.

Recommendations

For best performance, use the cable for connections inside the same rack or adjacent racks; avoid spanning long distances. Inspect QSFP connectors before insertion to prevent debris or damage. Maintain bend radius limits typical for copper QSFP cables and keep cable runs tidy to preserve cooling and accessibility in dense rack installations.
