CBO QSFP σε 4x SFP+ καλώδιο breakout 1 m BlueOptics (CBO 740-038152-BL)

The CBO QSFP to 4x SFP+ Breakout Cable 1 m BlueOptics is a direct-attach copper cable that converts a single QSFP port into four SFP+ ports. This 1 metre cable features a QSFP male connector on one end and four SFP+ male connectors on the other, enabling aggregation or breakout of a 40Gbps QSFP link into up to four 10Gbps SFP+ links where supported by the host hardware. The cable is designed for short-reach interconnects in racks, server rooms and network closets and provides a compact, cost-effective alternative to optical transceivers and patching when SFP+ connectivity is required from a QSFP port.

Advantages

The cable delivers simple, plug-and-play conversion between QSFP and SFP+ interfaces without the need for external power or media converters. Its direct-attach copper construction reduces latency and power consumption compared with active optical solutions for short distances. The single-cable breakout format saves port space and cabling complexity when connecting multiple 10GbE devices to a 40GbE QSFP port. The BlueOptics design ensures consistent electrical characteristics and reliable mating with compliant QSFP and SFP+ ports.

Suitable for

• Splitting a 40Gbps QSFP port into four 10Gbps SFP+ links for server-to-switch connections
• Short-reach uplinks between switches and aggregation devices in data centers
• Direct-attach connections between storage arrays and host adapters supporting SFP+
• Compact cabling runs inside racks and network cabinets where optical transceivers are not required

Key specifications

• Cable type: direct-attach copper breakout
• Connector ends: 1 x QSFP male to 4 x SFP+ male
• Length: 1 metre
• Supported per-lane rate: up to 10 Gbps per SFP+ lane (aggregate 40 Gbps where supported)
• Typical use: short-reach, within-rack and adjacent-rack connections
• Colour: blue

How to use

Insert the QSFP connector into a compatible QSFP port on your switch, router or network adapter, and plug the SFP+ connectors into the target SFP+ ports on servers, switches or storage devices. Ensure both ends are fully seated and latched according to the host device instructions. Check host hardware documentation to confirm that QSFP breakout to SFP+ is supported and that the port is configured for the intended aggregated or discrete 10GbE operation. No additional drivers are required for the cable itself, but you may need to configure link settings on the connected devices.

Recommendations

Use this breakout cable for short intra-rack connections and avoid bending the cable beyond manufacturer-specified bend radii. Verify compatibility of the switch or adapter with QSFP-to-SFP+ passive breakouts and confirm supported link speeds before deployment. For runs longer than one metre or for environments requiring optical isolation, choose appropriate active optical or fiber solutions.
