SFP28 DAC Cable BlueOptics SFP28-DAC-5M-AT 5m Male/Male

The BlueOptics SFP28-DAC-5M-AT is a 5 meter direct attach copper (DAC) cable with SFP28 male connectors on both ends. Designed for short-reach high-speed connections, this cable provides a straightforward physical layer link between compatible SFP28 ports on switches, routers, servers and storage equipment. It is intended for environments where low latency and reliable 25Gbps connectivity are required and where a fixed-length copper interconnect is the preferred solution.

Advantages

The cable delivers a cost-effective, low-power alternative to active optical modules for short connections, offering simple plug-and-play installation without the need for additional transceivers. Its copper construction ensures low latency and consistent signal integrity over the specified 5 m length. The SFP28 male-to-male form factor ensures direct compatibility with SFP28 slots on networking equipment that support passive DACs.

Suitable for

• Connecting switches and top-of-rack servers within the same rack or across adjacent racks
• Linking storage arrays and host adapters in data center environments
• Short-reach 25Gbps uplinks and switch-to-switch interconnects
• Laboratory and test bench setups requiring repeatable, low-latency connections

Key specifications

• Connector type: SFP28 male to SFP28 male
• Cable length: 5 meters
• Supported data rate: 25 Gbps per lane (SFP28 specification)
• Cable media: direct attach copper (passive DAC)
• Typical use: short-reach interconnects in data centers and server rooms
• Colour: black
• Weight: 0.08 kg

How to use

Install the BlueOptics SFP28 DAC by inserting each SFP28 male connector into the corresponding SFP28 port until the latch engages. Ensure both devices support passive DAC cables and are powered down or configured to accept hot-plug connections according to the equipment manufacturer’s guidelines. After insertion, verify link status and network configuration on the connected devices. For removal, depress the connector latch and pull straight out to avoid damaging the port.

Recommendations

Use this 5 m DAC cable for intra-rack and short inter-rack connections where 25Gbps performance is needed and optical transceivers are not required. Avoid sharp bends and excessive tension on the cable, maintain recommended bend radius, and keep the connectors free of dust when not in use to preserve signal integrity and prolong service life.
