## Summary description

The BlueOptics 720-084605-BL is a 3 m InfiniBand/fibre optic cable with SFP28 connectors. It features male-to-male connectivity, ensuring high-speed data transfer for networking applications. Ideal for data centers and high-performance computing environments.

## Long description

The BlueOptics InfiniBand/fibre optic cable 3 m SFP28 Black 720-084605-BL is a 3 metre direct attach solution with SFP28 connectors designed for short-range, high-speed links in server racks and adjacent rack cabinets. This cable supports 25G data rates and male-to-male SFP28 connectivity, enabling reliable electrical signal transmission for Ethernet, FCoE, Fibre Channel and InfiniBand applications where SFP28 ports are available. The cable is a passive twinax-style assembly with 30 AWG conductors and complies with common MSA physical and electrical guidelines to match standard SFP28 host ports.
Advantages
This 3 m SFP28 cable offers straightforward rack-to-rack or intra-rack connectivity with low latency and low power characteristics typical of passive direct attach cabling. It is built to industry mechanical and electrical standards and uses conductor and connector designs suitable for short-distance 25G links. The compact, fixed-length form factor simplifies installation, reduces the need for separate transceivers, and keeps total link cost and power consumption lower than active optical transceiver solutions.
Suitable for
Connecting SFP28 ports between switches and top-of-rack devices within the same or adjacent rack
Short-distance server-to-switch links in data centres and colocation facilities
High-performance computing clusters and storage systems requiring 25G interconnects
Environments using Ethernet, FCoE, Fibre Channel or InfiniBand at up to 25 Gbit/s over short runs
Key specifications
Length: 3 metres
Connector type: SFP28 male to SFP28 male
Data rate: up to 25 Gbit/s per link (supported protocols depend on host hardware)
Cable type: passive twinax-style direct attach assembly
Conductor gauge: 30 AWG
Colour: black
How to use
Install the cable by inserting each SFP28 plug into compatible SFP28 ports on the devices to be linked, ensuring the latching mechanism engages. Confirm that the connected hardware supports passive SFP28 direct attach copper assemblies and that the interfaces are configured for the desired protocol and speed. No additional power source is required for the cable itself; link parameters such as speed and autonegotiation are managed by the connected equipment. For best performance, avoid tight bends and keep the cable routed within recommended bend radius limits.
Usage recommendations
Use this cable for short, fixed-length connections where low latency and low power are priorities. Verify compatibility with your switch, router or storage platform vendor documentation before deployment and test the link after installation to confirm expected throughput and link stability.
