CBO QSFP BlueOptics BO252503K5M / Mellanox MC2210310-005 5m optical cable

The CBO QSFP BlueOptics BO252503K5M / Mellanox MC2210310-005 5m optical cable is a passive QSFP fiber assembly designed for short-range, high-density data center interconnects. Intended for direct fiber links between QSFP-equipped switches, servers and transceivers, this fixed 5-metre cable offers a compact, low-latency connection that simplifies rack cabling and minimizes signal conversion points. The cable supports standard QSFP port interfaces and is suitable for environments where reliable, short-distance optical transmission is needed.

Advantages

This passive QSFP optical cable provides a stable optical path with low insertion loss and predictable performance across short distances. Its fixed-length design reduces the need for patch panels and intermediate connections, lowering potential points of failure and simplifying cable management in dense racks. Compatible with QSFP form-factor ports, the cable enables straightforward installation and consistent interoperability with equipment that accepts QSFP fiber assemblies.

Suitable for

• Switch-to-switch links inside the same rack or adjacent racks
• Switch-to-server connections using QSFP ports
• Short-distance fiber runs in data centers and network closets
• High-density cabling setups that require predictable optical performance

Key specifications

• Connector type: QSFP optical interfaces (QSFP form-factor)
• Length: 5 metres
• Transmission type: Passive optical fiber (single fixed-length assembly)
• Typical application: Short-reach data center interconnects and switch links
• Physical characteristics: Compact cable assembly for high-density racks

How to use

Install the cable by aligning and inserting each QSFP connector into corresponding QSFP ports on switches, servers or transceivers until the connector latches. Ensure both ends are clean and free of dust before connection to avoid signal degradation. Route the 5-metre cable along rack management channels to prevent sharp bends and mechanical strain. Verify link status on connected devices after installation and perform standard diagnostics if necessary.

Recommendations

To maintain optimal performance, keep connector end-faces clean, avoid tight bends that exceed the fiber bend radius, and use proper rack management to reduce stress on connectors. For best results in interoperable deployments, confirm device compatibility with QSFP passive optical assemblies and follow vendor guidance for QSFP port handling.
