Cable breakout de fibra óptica CBO QSFP-4X10G-C5M-BL 5 m 40 Gbit/s QSFP+ a 4×10G SFP+ macho-macho

Cable CBO QSFP-4X10G-C5M-BL is a 5 m fibre optic breakout assembly designed to split a single 40 Gbit/s QSFP+ link into four independent 10 Gbit/s SFP+ channels. The assembly features a QSFP+ male connector on one end and four SFP+ male connectors on the other, providing a compact, single-cable solution for short-reach connections in data centres and networking racks. The cable supports aggregate throughput of 40 Gbit/s and is suitable for use where a QSFP+ to 4×10G breakout is required for switch-to-switch links, server uplinks or consolidation of optical ports.

Advantages

This breakout cable reduces the need for additional fibre patching and external splitters by integrating the QSFP+ to 4×SFP+ conversion in one assembly, simplifying rack cabling and reducing installation time. The fixed-length construction and factory-terminated connectors ensure consistent optical performance and lower insertion loss compared with field-terminated assemblies. Its 5 metre length offers flexibility for common rack and cabinet layouts while maintaining short-reach signal integrity.

Suitable for

• Data centre top-of-rack and spine connections
• Switch-to-switch aggregation and uplinks
• Server or storage host uplinks requiring 4×10G channels from a single 40G port
• Environments needing compact QSFP+ to SFP+ breakout cabling

Key specifications

• Aggregate throughput: 40 Gbit/s (4 × 10 Gbit/s)
• Cable length: 5 m
• Connector types: QSFP+ male on one end, four SFP+ male on the other end
• Cable function: Breakout / fan-out fibre assembly
• Intended reach: Short-reach intra-rack or inter-rack connections

How to use

Connect the QSFP+ male connector to the 40G QSFP+ port on the switch or transceiver module, and insert the individual SFP+ male connectors into the target 10G SFP+ ports on switches, servers or other network equipment. Ensure that the connected devices support QSFP+ breakout to 4×10G and configure port mapping or lane assignment in the device firmware if required. Handle the cable by the connectors and jacket, avoid sharp bends and maintain recommended bend radius to preserve optical performance.

Recommendations

Use this breakout cable in structured cabling within racks and short inter-rack runs where a fixed-length, factory-terminated QSFP+ to 4×SFP+ solution is preferred. Verify compatibility with equipment vendor breakout support and keep connectors clean to ensure reliable 10G links.
