## Summary description

BlueOptics SFP-25G-DAC-50CM-BL is a 0.5 m direct attach copper (DAC) twinax cable with SFP28 connectors designed for 25 Gigabit Ethernet links. The passive SFP28 cable provides a short-reach, low-latency connection between network devices such as switches, servers and NICs. Suitable for rack-to-rack and intra-rack connections where a fixed short-length copper link is required.

## Long description

BlueOptics SFP-25G-DAC-50CM-BL is a 0.5 m direct attach copper (DAC) twinax cable with SFP28 connectors engineered for 25 Gigabit Ethernet links. The passive SFP28 cable delivers a short-reach, low-latency copper connection between compatible network devices, enabling direct device-to-device links without additional transceivers. Its fixed 0.5 m length and SFP28 form factor make it suitable for dense rack environments and high-speed server or switch interconnects.
Advantages
The passive design ensures low power consumption and minimal latency compared with optical transceivers. Built with SFP28-compatible connectors and a 25 Gbps data rate, the cable provides a reliable, single-cable solution for short-distance connections. Its compact twinax construction reduces cable bulk in high-density racks while maintaining signal integrity for 25 Gigabit Ethernet applications.
Suitable for
 Rack-to-rack short interconnects in data centers
 Intra-rack connections between switches, servers and NICs
 High-density switch uplinks and server aggregation
 Low-latency links for storage and compute clusters
Key specifications
 Connector type: SFP28 (two ends)
 Cable type: Twinax direct attach copper (DAC)
 Length: 0.5 m
 Supported data rate: 25 Gbps
 Link reach: short-reach, intra-rack and rack-to-rack
 Power: passive (no external power required)
 Latency: low, suitable for latency-sensitive applications
How to use
Insert each SFP28 connector into the corresponding SFP28 port on the network devices until the latch engages. Ensure both devices support 25 Gigabit Ethernet over passive twinax DAC and that link settings (speed and duplex) are configured as required. No additional configuration is typically needed beyond verifying link negotiation and device compatibility. Handle the cable by the connector bodies when installing or removing to avoid stress on the cable assembly.
Usage recommendations
Use this 0.5 m SFP28 DAC for short, fixed connections where a stable, low-latency copper link is preferred over optical transceivers. Verify device compatibility with SFP28 passive DACs and avoid exceeding the specified bend radius to maintain performance.
