Cavo ottico passivo AOC SFP28 CBO SFP28-AOC-50M 50 m

The AOC SFP28 Passive Optical Cable CBO SFP28-AOC-50M 50 m is a factory-terminated active optical cable designed for direct connection of SFP28 ports supporting 25GbE and compatible high-speed links. With a fixed 50 m length, this passive AOC simplifies interconnection between switches, servers and transceivers in rack and data centre environments by providing a low-loss optical path that avoids field termination and reduces installation complexity.

Advantages

This pre-terminated optical solution delivers consistent signal integrity over 50 metres, reduces the need for separate transceivers and patch cords, and minimizes insertion loss compared with many copper alternatives. The cable’s passive AOC design ensures low latency and stable throughput for 25GbE connections, while its factory assemblies and standard SFP28 interfaces enable plug-and-play installation with compatible network equipment.

Suitable for

• Short- to mid-range 25GbE links between top-of-rack and aggregation switches
• Direct server-to-switch connections in data centre racks
• High-density network deployments where consistent optical performance is required
• Environments that benefit from pre-terminated cabling to reduce rack installation time

Key specifications

• Connection type: SFP28 to SFP28 optical AOC
• Supported data rate: 25 Gbps (compatible with 25GbE links)
• Length: 50 metres fixed
• Cable type: Passive active optical cable (factory-terminated duplex)
• Typical use: Single-mode or multimode compatibility as required by SFP28 transceivers (confirm transceiver type for distance and modal requirements)
• Latency: low, suitable for high-throughput server and switch interconnects

How to use

Install the cable by inserting each SFP28 connector into the corresponding SFP28 port on the network devices, ensuring the connectors are fully seated and any dust caps are removed prior to insertion. Verify link status on both devices and confirm the equipment’s compatibility with a passive AOC and 25GbE operation. Route the cable within the rack to avoid tight bends and mechanical stress; secure as needed with Velcro or cable management to maintain bend radius and airflow.

Recommendations

Check the transceiver compatibility and supported link distances of your switches and servers before deployment. Use the 50 m fixed length for planned rack-to-rack or rack-to-aggregation connections and avoid bending the cable beyond the manufacturer’s minimum bend radius to preserve optical performance.
