## Summary description

SFP28 Direct Attach Cable by BlueOptics, model S1S28P302.0-01P-BL, is a 2-meter copper twinax assembly compliant with 25GBASE-CR for short-reach 25 Gb/s connections. Designed for SFP28 ports, it provides a fixed, low-latency link for switches, servers and network equipment in data centers and rack-to-rack interconnects.

## Long description

BlueOptics SFP28 Direct Attach Cable 25GBASE-CR, 2 m, is a factory-terminated copper twinax assembly engineered for short-reach 25 Gb/s links. Designed for SFP28 ports, this fixed cable provides a low-latency, power-efficient physical connection between switches, servers and other network devices in data centers and rack-to-rack environments. The blue jacket identifies the cable visually while the compact SFP28 connector form factor supports high-density port implementations.
Advantages
This direct attach cable offers low latency and low power consumption compared with optical transceivers and separate fibre assemblies. Its fixed twinax construction reduces the number of field-terminated connections and simplifies deployment for point-to-point links. The 2 m length balances reach for adjacent racks or equipment within the same rack row while preserving signal integrity for 25GBASE-CR operation. The SFP28 form factor ensures compatibility with equipment that accepts SFP28 copper assemblies.
Suitable for
 Short-reach 25 Gb/s connections between switches and top-of-rack servers
 Rack-to-rack interconnects within the same data hall or cabinet
 High-density port deployments where SFP28 interfaces are available
 Low-latency applications such as virtualization hosts and storage networks
Key specifications
 Data rate: 25 Gbit/s (25GBASE-CR compatible)
 Connector type: SFP28 fixed twinax assembly
 Length: 2 meters
 Cable type: Copper twinax
 Jacket colour: Blue
 Reach: Short-reach/rack-level interconnect
 Latency: Low (direct attach passive copper)
How to use
Install by inserting each SFP28 connector into the corresponding SFP28 port on the two devices to be linked, ensuring the modules click into place. Confirm port configuration and link speed on both devices; most equipment will auto-negotiate 25 Gb/s when compatible transceiver cables are detected. Route the cable to avoid sharp bends and mechanical stress, and secure it with cable management to prevent strain on the connectors. No additional transceiver modules or fibre patch cords are required for a direct attach connection.
Usage recommendations
Use this 2 m SFP28 direct attach cable for short, high-density interconnects inside racks or between adjacent racks. Verify SFP28 port compatibility with copper twinax assemblies in equipment documentation and ensure proper airflow and cable management to maintain signal integrity and serviceability.
