BlueOptics XS+DA0003-BL InfiniBand/optický kabel 3 m SFP28 samec/samec

The BlueOptics XS+DA0003-BL InfiniBand/fibre optic cable 3 m SFP28 Male/Male is a 3‑meter direct attach cable designed for short‑reach, high‑speed connections between SFP28 ports. Built as a passive 25G twinax copper DAC with SFP28 male connectors on both ends, it supports up to 25 Gbit/s data rates for InfiniBand and Ethernet class applications and is intended for rack‑to‑rack and adjacent‑rack interconnects in data centers and server rooms.

Advantages

The cable provides a compact, low‑latency link with low power consumption typical of passive twinax designs. Constructed to MSA compliance and using high‑quality components, it is suitable for environments where reliable short‑distance 25G connectivity is required. Its fixed 3 m length simplifies installation in rack setups and reduces the need for external transceivers, lowering overall connectivity cost and complexity.

Suitable for

• Connecting SFP28 ports on switches and routers within or between adjacent racks
• Short‑reach InfiniBand and 25G Ethernet links in data centers
• Storage system interconnects and server uplinks requiring 25G direct attach

Key specifications

• Connector type: SFP28 male to SFP28 male
• Length: 3 metres
• Cable type: Passive twinax copper (DAC)
• Supported data rate: up to 25 Gbit/s
• Compliance: MSA compatible; 30 AWG conductor gauge

How to use

Insert one SFP28 connector into the SFP28 port of the first device and the other connector into the corresponding SFP28 port of the second device. Ensure both devices support passive 25G DACs and that ports are configured for the intended protocol (Ethernet, InfiniBand, FCoE, or Fibre Channel where applicable). Route the cable through the rack to avoid sharp bends; maintain the specified minimum bend radius and avoid mechanical strain on the connectors. No external power or transceivers are required for the passive cable to operate.

Recommendations

Verify hardware compatibility with passive 25G DACs before deployment. For best performance, use the cable for connections up to 3 m and within rack or adjacent rack distances. Avoid exposing the cable to excessive heat or mechanical stress, and perform periodic visual checks of connectors to ensure clean contact surfaces.
