## Long description

The BlueOptics SFP28-DAC-3M-BC 3m Male Connector is a 3‑meter SFP28 Direct Attach Copper (DAC) cable intended for short‑reach, high‑speed connections between network equipment. Designed for SFP28 ports, this cable supports 25Gbps data rates and provides a fixed, low-latency electrical link suitable for server-to-switch and switch-to-switch connections in data center environments. The blue jacket makes cable routing and identification easier in dense racks.
Advantages
This DAC cable offers low power consumption, predictable latency and reliable physical connectivity without the need for transceivers. As a passive/copper direct attach solution it reduces system complexity and lowers total cost for short-distance links. The standardized SFP28 male connectors ensure compatibility with equipment using SFP28 ports and simplify installation and replacement.
Suitable for
25GbE server-to-switch connections in data centers
Switch-to-switch uplinks within the same rack or adjacent racks
High-performance computing and InfiniBand environments requiring low latency
Temporary or permanent cabling where short, reliable copper links are preferred over optical transceivers
Key specifications
Cable type: SFP28 Direct Attach Copper (DAC)
Length: 3 metres
Connector type: SFP28 male on both ends
Data rate: designed for 25 Gbps operation
Casing colour: blue
Typical use: short‑reach, rack‑level connections
How to use
Confirm that both devices have compatible SFP28 ports and that the required data rate is supported. Power down or follow hot‑swap guidance from your equipment manufacturer, insert each SFP28 connector into the corresponding port until it clicks, and secure cable routing to avoid sharp bends. Verify link status via the network equipment indicators or management interface. For best signal integrity, avoid excessive cable tension and maintain recommended bend radius.
Usage recommendations
Use the cable for rack‑level connections up to 3 metres; for longer distances consider optical transceivers and fibre optic cabling. Keep the connectors free of dust and handle the cable by the connector housings when plugging or unplugging to minimise strain on ports and maintain reliable performance.
