## Summary description

CBO BlueLAN 100G-QSFP-4SFP-P-0501 is a passive DAC direct attach copper cable with a QSFP28 connector supporting 100G links and breakout to four SFP+ ports. Designed for short-reach connections in racks and data center top-of-rack switches, it provides low-latency, low-power interconnect for server, switch and storage equipment.

## Long description

CBO BlueLAN 100G-QSFP-4SFP-P-0501 is a passive direct attach copper (DAC) cable with a QSFP28-to-4×SFP+ breakout configuration for 100G links. It is intended for short-reach interconnects inside racks and between top-of-rack switches, providing a compact, low-latency physical connection for servers, switches and storage devices. The passive construction requires no external power or active electronics, enabling simple, cost-effective deployment where fiber transceivers are not required.
Advantages
The cable delivers a direct 100G connection with the option to break out into four 25G/10G SFP+ links, reducing the number of required ports and simplifying cabling in dense deployments. Passive copper construction offers low latency and minimal power consumption compared with active optical or electrically amplified solutions. Its QSFP28 to 4×SFP+ compatibility supports mixed-speed environments and allows flexible port population in data center topologies.
Suitable for
Short-reach rack-to-rack or server-to-switch interconnects
Top-of-rack switch connections in data centers
Aggregating multiple SFP+ links into a single 100G QSFP28 port
Low-latency connectivity for storage and compute clusters
Key specifications
Connector type: QSFP28 to 4×SFP+
Supported link speed: 100 Gbps (breakout to four 25 G/10 G lanes)
Cable type: passive copper direct attach
Reach: designed for short-reach, in-rack and top-of-rack connections
Latency: low, passive electrical interconnect
Power: passive, no external power required
How to use
Insert the QSFP28 end into the 100G QSFP port on the switch or network device and insert each SFP+ plug into the corresponding SFP+ ports on servers or other network equipment. Ensure both ends are fully seated and the link partners support breakout mode if aggregating multiple SFP+ links. Verify link status through device LEDs or management interfaces before relying on the connection for production traffic.
Usage recommendations
Use this passive DAC for short, in-rack connections where low latency and low power are priorities. Avoid installing the cable across long distances or in environments with excessive electromagnetic interference. Confirm compatibility with switch firmware and port breakout settings to ensure proper operation.
