Cavo ottico attivo CBO SFP28-AOC-20M-DL-BO 20 m SFP28 compatibile D-Link

Active Optical Cable CBO SFP28-AOC-20M-DL-BO is a 20-metre SFP28 form-factor fiber cable engineered for 25Gbps links between servers, switches and storage devices. The cable integrates active optical transceivers in an SFP28 enclosure, enabling direct connection to compatible SFP28 ports and minimizing the need for separate transceivers. Its optical construction reduces electromagnetic interference and signal loss over short to mid-range distances, making it suitable for data centre and campus interconnects that require consistent low-latency performance.

Advantages

The active optical design offers lower weight and better thermal characteristics than equivalent copper assemblies and eliminates crosstalk issues inherent to copper cabling. Native SFP28 form factor ensures plug-and-play compatibility with devices supporting SFP28 modules from the same vendor family, simplifying rack-to-rack and shelf-to-shelf connections while keeping port density high. The optical medium maintains signal integrity across the full 20 m length, delivering stable 25Gbps throughput with reduced EMI concerns.

Suitable for

• Short- to mid-range server-to-switch connections in data centres
• Switch-to-switch links within server racks and across adjacent racks
• High-performance storage network connections requiring 25Gbps bandwidth
• Campus network backbones where reduced electromagnetic interference is required

Key specifications

• Connector type: SFP28 form factor transceivers integrated into the cable ends
• Data rate: 25 Gbps per channel
• Length: 20 metres
• Medium: optical fiber with active transceiver electronics
• Typical use range: short- to mid-range interconnects (up to 20 m)
• Latency: low, suitable for latency-sensitive applications

How to use

Install the cable by inserting each SFP28 end into the corresponding SFP28 port on the networking devices until the latch engages. Ensure both devices are powered and configured to use 25Gbps SFP28 links; the connected equipment should recognise the module as an SFP28 optical link if the ports support compatible transceivers. Route the cable to avoid sharp bends and excessive strain; maintain bend radii recommended for optical fiber to preserve signal quality. No separate transceivers or patch panels are required when using the integrated SFP28 ends.

Recommendations

Verify device compatibility with SFP28 optical modules and confirm firmware or vendor interoperability lists when connecting equipment from different manufacturers. Avoid tight bending and kinking, keep connectors clean, and handle the cable by the transceiver housings rather than the fiber to prevent damage. For critical links, check link status and error counters after installation to confirm stable 25Gbps operation.
