InfiniBand/kuitu-kaapeli BlueOptics 844483-B21-BO 7 m SFP28 uros/uros

The BlueOptics 844483-B21-BO is a 7 m InfiniBand/fibre optic active optical cable (AOC) with SFP28 male-to-male connectors designed for high-speed data transmission in data center and networking environments. It supports 25GBASE-SR4 multimode operation with integrated transmitter and receiver modules on each end, enabling simultaneous send/receive optical communications over a 7 meter multimode fiber link. The cable follows MSA standards and is compatible with major hardware platforms that accept SFP28 25G AOCs.

Advantages

This BlueOptics AOC provides low-latency, EMI-immune optical connectivity with pre-terminated SFP28 interfaces for plug-and-play installation. Built to MSA specifications, the cable features active optical transceivers that include digital diagnostic monitoring (DDM/DOM) for real-time metrics such as supply voltage, laser bias current, output and received optical power, and temperature. Component selection from established manufacturers and factory testing for platform compatibility contribute to a long operational lifetime and stable data links.

Suitable for

• High-speed Ethernet links up to 25 Gbit/s in data centers
• Fibre Channel over Ethernet or storage networking between switches and storage arrays
• Short-reach connections between switches, routers and servers using SFP28 ports
• Environments requiring EMI-resilient optical interconnects and low latency

Key specifications

• Length: 7 meters
• Connector type: SFP28 male to SFP28 male
• Transmission standard: 25GBASE-SR4 (multimode)
• Media: multimode fiber with integrated active optical transceivers
• Data rate: up to 25 Gbit/s per cable
• Digital diagnostics: DDM/DOM (real-time monitoring of optical and electrical parameters)
• MSA-compliant SFP28 interface

How to use

Insert the SFP28 connectors into compatible SFP28 ports on network devices such as switches, routers or servers until they click into place. Ensure both ends are connected to devices that support 25GBASE-SR4 AOC modules and, if necessary, verify that the host hardware accepts third-party AOCs. Use the host interface or management software to read DDM/DOM values for monitoring link status. Route the cable to avoid sharp bends and mechanical stress; no additional patching or fiber termination is required.

Recommendations

Confirm device compatibility and DDM/DOM support before deployment. Avoid tight bends and excessive pulling force, keep connectors covered when not in use, and perform routine checks of diagnostic parameters to ensure optical link health and optimal performance.
