Product information

Description

The BlueOptics SFP28-DAC-3M-LC-BL is a 3‑metre SFP28 direct attach copper (DAC) cable with SFP28 male connectors on both ends, designed for short‑reach, high‑speed interconnects in racks and adjacent rack aisles. It implements a passive twinax copper design suitable for 25GBase‑CR electrical links and is intended for use with equipment that supports SFP28 passive DAC cables. The cable is specified for short‑distance electrical transmission and is available in a black jacket with a blue connector designation.

Advantages

This SFP28 DAC cable provides a low‑latency, low‑power solution for direct device connections, eliminating the need for separate transceivers at each end. Its passive twinax construction reduces failure points compared with active modules and offers a straightforward plug‑and‑play connection where the host hardware supports passive DACs. The 3 m length is suitable for top‑of‑rack and adjacent‑rack links while maintaining signal integrity for 25 Gbps applications.

Suitable for

  • Top‑of‑rack and adjacent‑rack switch interconnects in data centers
  • 25 Gbps server-to-switch and switch-to-switch links
  • High‑performance computing clusters and storage system connections
  • Environments requiring low power consumption and low latency short‑reach links

Key specifications

  • Type: SFP28 direct attach cable (DAC), passive twinax copper
  • Connector: SFP28 male to SFP28 male
  • Nominal data rate: up to 25 Gbps per lane (25GBase‑CR applications)
  • Length: 3 metres
  • Wire gauge: 30 AWG twinax conductor
  • Casing colour: black with blue connector designation
  • Typical use: short‑reach electrical interconnects in racks
  • Compliance: designed to meet SFP28 MSA electrical and mechanical interfaces
  • Weight (approx.): 0.08 kg

How to use

Confirm that both devices support passive SFP28 DAC cables and the 25GBase‑CR electrical interface. With devices powered down or in accordance with the vendor’s hot‑swap guidance, insert each SFP28 connector into the corresponding SFP28 port until the latch clicks. Route the cable to avoid sharp bends and mechanical strain; maintain the minimum bend radius recommended by the equipment manufacturer. After installation, verify link status in the host equipment and confirm negotiated link speed is 25 Gbps where applicable.

Usage recommendations

Use this 3 m passive SFP28 DAC cable for short‑distance rack and adjacent‑rack connections where low latency and low power consumption are priorities. Avoid exceeding the recommended bend radius, keep the cable clear of heat sources, and ensure both endpoints explicitly support passive SFP28 twinax DACs to guarantee compatibility and reliable operation.
