CBO DAC SFP28 BlueLAN SFP-25G-C1M cable Direct Attach 25Gbps, 1 m

CBO DAC SFP28 BlueLAN SFP-25G-C1M 25Gbps Direct Attach Cable 1m is a passive SFP28 copper cable engineered for short-reach, high-bandwidth connections. With SFP28 terminations and a 1-meter length, this Direct Attach Cable supports 25Gbps data throughput and is intended for direct interconnects between switches, routers and network interface cards in rack-to-rack or intra-rack deployments. The cable provides a low-latency, energy-efficient and cost-effective alternative to optical transceivers for dense server and switch environments.

Advantages

The cable delivers 25Gbps line-rate performance with native SFP28 compatibility, eliminating the need for separate optical modules or fiber patching for short distances. Passive construction reduces power consumption compared with active optics and simplifies installation by using familiar SFP28 ports. Its fixed 1 m length minimizes excess cabling in rack setups and helps maintain predictable signal integrity for short interconnects.

Suitable for

• Short-reach connections between top-of-rack and aggregation switches
• Server to switch direct links within a rack
• High-density data center interconnects where cost and power efficiency are priorities
• Network interface card (NIC) to switch connections requiring 25Gbps bandwidth

Key specifications

• Connector type: SFP28 (both ends)
• Data rate: 25 Gbps
• Length: 1 meter
• Media: Twinax copper cable (passive)
• Typical use case: Short-reach, direct attach interconnects
• Compatibility: SFP28 ports on switches, routers and NICs supporting 25Gbps DACs

How to use

Insert each SFP28 connector into the corresponding SFP28 port on the two devices to be connected until the latch engages. Verify link negotiation and 25Gbps operation through the device management interface or port LEDs. No additional transceivers, fiber patch cords or optical modules are required. For hot-plug operations, follow your equipment vendor’s guidance to avoid momentary link interruptions.

Recommendations

Use this 1 m passive DAC for short, fixed-length interconnects inside racks or between adjacent racks. Ensure both endpoints support SFP28 passive copper cables and check firmware or switch compatibility lists if uncertain. Avoid sharp bends or kinks in the twinax cable and maintain standard airflow and cable management practices to preserve performance and reliability.
