InfiniBand/kuitu-kaapeli BlueOptics 720-084604-BL 1 m SFP28 uros/uros

The BlueOptics 720-084604-BL is a 1 m InfiniBand/fibre optic/DAC cable with SFP28 male connectors on both ends. Designed for short-range, high-speed interconnects, this cable supports 25G data rates and is intended for use in racks and between adjacent racks where SFP28 ports are available. The passive direct attach twinax construction provides a compact, low-latency link for switches, routers, storage systems and other network devices that accept SFP28 to SFP28 direct attach connections.

Advantages

This 1 m SFP28 male-to-male cable offers reliable 25G connectivity with low power consumption and minimal latency typical of passive twinax direct attach solutions. It is MSA-compliant and built to be compatible with hardware platforms that support the corresponding original cabling standard. The compact, shielded twinax design simplifies rack cabling and reduces signal loss over short distances while providing a cost-effective alternative to active optical assemblies for closest-placed equipment.

Suitable for

• Short-range connections between rack-mounted switches and servers with SFP28 ports
• Interconnects between adjacent racks or within the same rack
• 25G Ethernet, FCoE, Fibre Channel or InfiniBand links when used with compatible hardware

Key specifications

• Connector type: SFP28 male to SFP28 male
• Length: 1 meter
• Rated data rate: up to 25 Gbit/s
• Cable type: passive twinax / direct attach
• Shielding: shielded twinax design for short-range high-speed links

How to use

Before installation, confirm that both devices support passive SFP28 direct attach cables and the 25G transmission protocol required for your application. Insert each SFP28 connector firmly into the SFP28 port until the latch engages. Route the 1 m cable to avoid sharp bends and mechanical strain on connectors. For redundant or multipath architectures, ensure proper link configuration in the switch or host interface firmware according to the vendor's instructions.

Recommendations

Use this cable for short-distance rack-level connections where low latency and low power consumption are priorities. Avoid extending beyond intended short-range use; maintain bend radii recommended for twinax cables and verify compatibility with device vendor support documentation when used in multi-vendor environments.
