## Summary description

CBO InfiniBand cable MA-CBL-40G-50CM-BL is a 0.5 m QSFP copper interconnect designed for short-reach high-speed connections. The cable supports 40 Gbit/s data throughput (as indicated by model name), features QSFP connectivity and a 0.5 m length for rack- and chassis-level links. It is suitable for linking switches, servers and storage in data centers where a short, reliable InfiniBand connection is required.

## Long description

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.
Usage 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.
