CBO AOC SFP28 BlueOptics BO272703Q10M 10 m active optical cable for 25GbE SFP28 ports

The CBO AOC SFP28 BlueOptics BO272703Q10M is a 10 m active optical cable designed for direct connections between 25GbE SFP28 ports. This pre-terminated, hot-pluggable cable integrates transceiver functionality in a compact assembly to deliver low-latency, high-bandwidth links for switches, servers and network interface cards without the need for separate transceivers. The cable reduces electromagnetic interference and is intended for short-reach data centre interconnects such as top-of-rack and adjacent-rack connections.

Advantages

This active optical cable offers a compact, lightweight solution that simplifies installation and inventory by removing the need for separate transceivers and patch cords. It provides consistent 25GbE throughput with low latency and reduced electromagnetic interference compared with copper alternatives. The hot-pluggable design enables quick replacement or reconfiguration without powering down equipment, while the optical medium supports longer reach and improved signal integrity over equivalent copper assemblies.

Suitable for

• Top-of-rack switch to server connections in data centres
• Switch-to-switch 25GbE links within cabinets and adjacent racks
• High-performance network interface card (NIC) direct connections
• Short-reach aggregation and leaf-spine fabric links where 25GbE is required

Key specifications

• Form factor: SFP28 active optical cable assembly
• Data rate: 25 Gbit/s per lane (25GbE link)
• Length: 10 metres
• Cable type: active optical with integrated transceiver functions
• Connector compatibility: SFP28 ports
• Latency: low optical latency suitable for server and switch interconnects
• Electromagnetic behaviour: optical medium reduces EMI compared with copper cables

How to use

Insert each SFP28 connector end into the corresponding SFP28 port on switches, servers or NICs until the latch engages. The assembly is hot-pluggable; devices typically recognise the link automatically and negotiate 25GbE operation. Ensure cable routing avoids excessive bending and strain on the connectors and follow standard data centre cable-management practices. Verify link status and speed through device management interfaces after connecting.

Recommendations

Use the cable for short-reach 25GbE interconnects inside cabinets or between adjacent racks. Maintain minimum bend radius as specified by the manufacturer, avoid exposure to sharp edges or crushing, and keep fiber ends and connector housings clean during insertion. For mixed-vendor environments, verify SFP28 compatibility and link negotiation in advance to ensure full interoperability.
