InfiniBand/fibre optic cable BlueOptics X66130-3-BL 3 m SFP28

The BlueOptics X66130-3-BL is a 3 m InfiniBand/fibre optic cable with SFP28 connectors on both ends. Designed for high-speed data transmission, this cable supports 25G connectivity over a short 3 meter link and is suitable for use in data centers, racks and adjacent rack connections where low latency and reliable throughput are required. The cable is compatible with equipment that supports SFP28 interfaces and is intended for environments that require consistent, short-reach high-bandwidth links.

Advantages

The cable offers a compact, fixed-length solution that simplifies rack-to-rack and in-rack connections while avoiding the need for transceivers. Its SFP28-to-SFP28 configuration enables direct attachment for supported ports, providing low latency and reduced power consumption compared with active optical solutions. Built to industry MSA guidelines, the product is made from high-quality components chosen for reliable signal integrity and long operational lifetime in professional network installations.

Suitable for

• Short-reach 25G links between switches and servers
• In-rack and adjacent rack connectivity in data centers
• High-throughput, low-latency storage and compute interconnects
• Environments using SFP28 ports for Ethernet, FCoE or InfiniBand-compatible traffic

Key specifications

• Connector type: SFP28 on both ends
• Length: 3 meters
• Data rate support: up to 25 Gb/s on short distances
• Cable type: direct attach (passive) suitable for short-reach applications
• Designed for rack and adjacent-rack interconnects with low latency

How to use

Install the cable by inserting each SFP28 connector into the corresponding SFP28 port on the networking devices, ensuring secure seating and proper orientation. Use in links up to the specified 3 meter length between compatible ports; the devices at each end must support passive direct-attach SFP28 connections. After physical installation, verify link status and speed through the network equipment management interface and perform data-path tests to confirm expected throughput and latency.

Recommendations

For reliable operation, route the cable to avoid sharp bends and mechanical stress, and keep it away from sources of strong electromagnetic interference. Confirm that connected hardware officially supports passive SFP28 direct-attach cables and update device firmware where necessary to ensure compatibility. Consider keeping spare cables of the same type on hand for rapid replacement in high-availability environments.
