BlueOptics XXVDACBL1M-BL InfiniBand-kuituvalokaapeli 1 m SFP28 uros

The BlueOptics XXVDACBL1M-BL InfiniBand Fibre Optic Cable 1m SFP28 Male is a 1‑meter direct attach cable designed for short-range high-speed connectivity in rack and adjacent-rack installations. It provides SFP28-to-SFP28 male connectors and supports up to 25 Gbit/s data rates for Ethernet, FCoE, Fibre Channel and InfiniBand protocols when used with compatible host ports. The cable follows MSA-compliant SFP28 electrical and mechanical specifications and is intended for professional network equipment such as switches, routers and storage systems that accept passive SFP28 direct attach twinax connections.

Advantages

The cable offers low latency and low power consumption typical of passive direct attach twinax solutions, while simplifying rack cabling with a fixed 1 m length and robust SFP28 male connectors. MSA compliance and the use of industry-standard components support broad interoperability across major hardware platforms. The passive design eliminates active transceivers, reducing failure points and enabling cost-effective deployment for high-density data center links.

Suitable for

• Short-range connections inside racks and between adjacent racks
• High-performance computing clusters and InfiniBand networks
• Switch-to-switch, switch-to-server and server-to-storage links supporting SFP28
• Environments requiring low-latency, low-power direct attach connectivity

Key specifications

• Connector type: SFP28 male to SFP28 male
• Length: 1 meter
• Data rate support: up to 25 Gbit/s per link
• Cable type: passive twinax/direct attach copper implementation for short distances
• Wire gauge: 30 AWG conductor
• Standards: MSA-compliant SFP28 electrical and mechanical interface

How to use

Insert each SFP28 male connector into the corresponding SFP28 port on the devices to be linked, ensuring both devices support passive 25G SFP28 direct attach twinax cables. No additional power or configuration is required at the cable level; connectivity and link parameters are negotiated by the connected devices according to their supported protocols. For initial deployment, verify link status and speed in device management interfaces and confirm compatibility with the host hardware and firmware versions.

Recommendations

For optimal performance, use this 1 m passive SFP28 cable for short interconnects inside racks or between adjacent racks where 25G speeds and low latency are required. Avoid routing the cable through sharp bends and keep it clear of high-electromagnetic-interference sources. Confirm device support for passive DAC operation and, if possible, test a sample in your target hardware before large-scale deployment.
