CBO AOC SFP28 25 Gbit/s AOC-SFP-25G-30M-BO 30 m aktívny optický kábel

CBO AOC SFP28 25Gbit/s AOC-SFP-25G-30M-BO 30 m active optical cable is a 30‑metre SFP28 direct‑attach solution designed to support 25 Gbit/s links between devices with SFP28 ports. The cable uses active optical transceivers integrated into the assembly to deliver high‑speed transmission with low latency, electrical isolation and reduced electromagnetic interference compared with equivalent copper assemblies. It is intended for short to mid‑range interconnects in data centre topologies, switch‑to‑switch links, and server uplinks where a reliable 25GbE connection over 30 metres is required.

Advantages

The active optical cable provides a stable 25 Gbit/s data rate with lower power consumption at longer distances than comparable copper cables. Optical transmission ensures electrical isolation between connected devices and reduces susceptibility to electromagnetic interference and crosstalk. Integrated SFP28 form‑factor transceivers simplify installation by plugging directly into SFP28 ports, eliminating separate transceiver modules and external fibre connectors. The 30 m length offers flexibility for rack‑to‑rack and across‑room connections within data centre environments.

Suitable for

• 25GbE switch‑to‑switch uplinks in data centres
• Server to top‑of‑rack switch connections
• Copper‑sensitive environments requiring electrical isolation
• Short to mid‑range fibre connections up to 30 metres

Key specifications

• Data rate: 25 Gbit/s per link
• Form factor: SFP28 active optical assembly
• Length: 30 metres
• Optical medium: active multimode/optical cable (integrated transceivers)
• Latency: low latency transmission suitable for high‑performance networking
• Electrical characteristics: provides galvanic isolation between endpoints
• Operating environment: designed for data centre and enterprise network use

How to use

Install the cable by inserting each SFP28 connector into the corresponding SFP28 port on the network devices until the latch engages. Ensure devices are powered and configured to support 25GbE SFP28 links; most modern switches and servers will automatically negotiate the connection. Route the cable to avoid sharp bends and mechanical stress and secure it to prevent strain on ports. No separate optical transceivers or patch cables are required because the active optical elements are built into the assembly.

Recommendations

For reliable operation, verify firmware and interoperability with the switch or server vendor and avoid tight bend radii or excessive pulling force. Use this AOC for in‑room or in‑rack connections up to 30 m; for longer links consider other optical transceiver and fibre options. Regularly inspect connectors for contamination and handle the SFP28 ends by the housing to prevent damage.
