## Summary description

The BlueOptics SFP28-DAC-3M-BL is a 3-meter DAC cable designed for high-speed data transmission. It features SFP28 connectors on both ends, making it ideal for connecting switches and servers in data centers. This cable ensures reliable performance and low latency, suitable for InfiniBand and fibre optic applications.

## Long description

The BlueOptics SFP28-DAC-3M-BL 3m SFP28 Connector is a 3‑metre direct attach copper (DAC) cable with SFP28 connectors on both ends, intended for high‑speed, short‑reach interconnects. Designed for use in data center environments, this cable supports 25 Gbps link speeds and provides a low‑latency physical connection between compatible SFP28 ports on switches, routers and servers. The cable’s fixed length and integrated connectors offer a compact, energy‑efficient alternative to optical transceivers for short connections.
Advantages
The cable offers predictable signal integrity and consistent latency due to its direct attach design and matched SFP28 connectors. Its 3 m length balances reach and cable management needs in racks and patch areas. As a passive DAC solution it typically consumes no additional power compared with active optical modules and removes the need for separate transceivers and patch cords for short links. The integrated design simplifies installation and reduces potential points of failure.
Suitable for
 Connecting top‑of‑rack switches to servers within the same rack or adjacent racks
 Short‑reach 25 Gbps links between network devices in data centres
 Low‑latency connections for high‑performance computing clusters and storage arrays
 Temporary or permanent interconnects in rack cabling and network test setups
Key specifications
 Connector type: SFP28 on both ends
 Length: 3 metres
 Supported data rate: 25 Gbps
 Transmission medium: direct attach copper (DAC)
 Typical use case: short‑reach, server‑to‑switch or switch‑to‑switch links
 Latency: low, suitable for latency‑sensitive applications
How to use
Insert each SFP28 connector into an empty SFP28 port on the devices you want to interconnect, ensuring proper alignment and a secure latch. Verify link status on both devices after installation and configure the interfaces according to your network settings. For reliable operation, avoid excessive bending near the connectors and route the cable to prevent mechanical strain. If your environment requires compatibility checks, confirm vendor interoperability with the SFP28 ports before deployment.
Usage recommendations
Use the cable for short‑distance 25 Gbps connections within racks or between adjacent racks; avoid extending beyond the recommended 3 m length and keep connectors clean to maintain signal quality. For longer distances or environments requiring optical isolation, consider using optical transceivers and fibre cabling instead.
