Direct Attach kábel CBO SFP28-DAC-5M-LS-BL 5 m samec-na-samca 25 Gbit/s SFP28

BlueOptics Direct Attach Cable CBO SFP28-DAC-5M-LS-BL is a 5 m passive male-to-male SFP28 cable engineered for 25 Gbit/s short-range connections. It connects SFP28 ports on servers, switches and network interface cards (NICs) with low latency and minimal power consumption. The cable is intended for rack-to-rack and in-rack interconnects in data center environments where cost-effective, high-density cabling is required. Plug-and-play operation eliminates the need for transceivers, simplifying installation and reducing overall equipment costs.

Advantages

The cable offers a reliable 25 Gbit/s link with passive SFP28 male connectors, ensuring compatibility with standard SFP28 ports and maintaining signal integrity over the 5 m length. Its passive design minimizes power draw compared with active solutions and reduces heat output in dense deployments. The single-cable solution lowers material and operational costs while simplifying cable management in crowded racks. Durable connector housings and a flexible jacket support repeated handling and routing in tight spaces.

Suitable for

• Short-range server-to-switch and switch-to-switch links in data centers
• NIC-to-switch connections for 25 Gbit/s network interfaces
• High-density rack interconnects and top-of-rack (ToR) cabling
• Environments requiring low latency and minimal power consumption

Key specifications

• Data rate: 25 Gbit/s
• Connector type: SFP28 male to SFP28 male
• Length: 5 metres
• Cable type: Passive direct attach cable
• Suitable for short-range, in-rack and rack-to-rack use
• Low power consumption due to passive design

How to use

Insert each SFP28 male connector into the SFP28 port on the respective device until it latches. Ensure ports on both devices are configured for matching link speed and duplex settings or set to auto-negotiate. No external power or transceivers are required. Verify link status on connected devices and confirm network parameters in the operating system or switch management interface. For removal, unlatch and pull connectors straight out to avoid damaging the ports.

Recommendations

Install the cable in cooled rack environments and avoid tight bends near the connector ends; maintain the manufacturer’s minimum bend radius to preserve signal integrity. Use in supported SFP28 ports and verify vendor compatibility if devices use vendor-lock mechanisms. For organized installations, label both ends and route the cable within cable management panels to reduce strain and improve airflow.
