## Summary description

Direct Attach Copper (DAC) SFP28 cable CBO JNP-25G-DAC-1M is a 1-metre short-reach twinax cable compatible with SFP28 ports for 25 Gigabit Ethernet connections. Designed for direct device-to-device links in racks and switches, it provides a fixed, low-latency physical connection without transceivers. Suited for data center interconnects, server uplinks and switch stacking where a reliable, plug-and-play 25Gbps link is required.

## Long description

Direct Attach Copper (DAC) SFP28 cable CBO JNP-25G-DAC-1M, 1 m length is a 1-metre twinax cable designed for SFP28 ports to support 25 Gigabit Ethernet connections. The cable provides a fixed copper link for short-reach device-to-device connections in racks, server aisles and network switches without the need for separate optical transceivers. Its purpose is to deliver a low-latency, high-bandwidth physical connection suitable for data center interconnects, server uplinks and switch stacking where a reliable 25Gbps link is required.
Advantages
The DAC SFP28 cable offers low insertion loss and minimal latency due to its direct copper twinax construction, providing stable electrical performance for short distances. As a pre-terminated, plug-and-play cable compatible with SFP28 ports, it eliminates the cost and power consumption associated with separate optical transceivers and simplifies installation. Its one-metre length reduces excess cabling in dense rack environments and helps maintain neat cable management while ensuring consistent 25Gbps throughput.
Suitable for
 Data center top-of-rack and server-to-switch connections
 Switch stacking and short rack-to-rack links
 High-speed uplinks between servers and network switches
 Environments requiring low-latency, short-reach copper connections
Key specifications
 Connector type: SFP28-compatible direct attach twinax
 Supported data rate: 25 Gigabit Ethernet
 Length: 1 metre
 Cable medium: copper twinaxial
 Typical use range: short-reach (intra-rack or adjacent racks)
 Power consumption: passive (no active transceiver electronics)
How to use
Insert each SFP28 connector end into the corresponding SFP28 port on the devices to be linked, ensuring secure latch engagement. No configuration is required at the physical layer beyond verifying port compatibility and link settings on connected devices. For initial deployment, confirm 25Gbps link negotiation and check for link LEDs or management interface indicators to verify connectivity. To remove the cable, release the connector latches and pull straight out to avoid stressing the port.
Usage recommendations
Use the 1 m DAC cable for short, direct connections inside racks or between adjacent rack units to minimize cable slack and maintain optimal airflow. Verify SFP28 port compatibility in device documentation and avoid excessive bending or pulling; observe manufacturer bend radius guidelines for twinax cable. For environments requiring longer reach or fiber isolation, consider optical transceivers and fiber cabling instead.
