CBO BlueOptics QSFP to 4×SFP+ Breakout Cable 1 m Male to Male (model 740-038153-BL)

The CBO BlueOptics QSFP to 4×SFP+ Breakout Cable 1 m Male to Male is a compact, factory-terminated assembly that splits a single QSFP port into four independent SFP+ ports. With a 1 meter length and direct-attach connectors, this breakout cable is intended for short-reach interconnects in high-density networking environments such as data centers, server racks and switch-to-module connections. The cable supports consolidation of high-speed links into smaller form-factor ports while keeping a straightforward, plug-and-play installation.

Advantages

This breakout cable provides a space-efficient way to expand port density without additional transceivers or fiber patching. The male QSFP and four male SFP+ connectors offer reliable electrical connections for short-reach multimode or copper links. Factory-terminated construction ensures consistent signal integrity and reduces field termination work. The 1 m length limits excess slack for tidy rack installations and minimizes insertion loss compared with longer assemblies.

Suitable for

• Aggregating or splitting 40G QSFP links into four 10G SFP+ links
• High-density top-of-rack or spine-and-leaf switch deployments
• Connecting blade servers, network modules and storage arrays with SFP+ ports
• Short-reach interconnects inside server cabinets and equipment enclosures

Key specifications

• Connector type: QSFP (male) to 4 × SFP+ (male)
• Cable length: 1 meter
• Data rates: supports 40G aggregated to four 10G lanes (electrical breakout)
• Orientation: direct-attach, factory-terminated assembly
• Use case: short-reach multimode or copper electrical interconnect

How to use

Insert the QSFP end into the host QSFP port on the switch or network device, making sure the latch is fully engaged. Route the cable to the target device and insert each SFP+ connector into the corresponding SFP+ port, ensuring correct alignment and secure seating. Verify link and LED indicators on both ends to confirm successful negotiation and link establishment. Avoid sharp bends and maintain manufacturer-recommended bend radius during installation.

Recommendations

For reliable performance, use this breakout cable for connections within the same rack or adjacent racks. Ensure the connected devices support QSFP-to-4×SFP+ electrical breakout and compatible speeds. Keep cable runs short and organized to maintain airflow and to reduce signal degradation; inspect connectors for debris before insertion.
