Aktívny optický kábel CBO SFP28-AOC-2M Viavi 2 m SFP28 25 Gb/s

CBO Viavi SFP28-AOC-2M is a 2 m Active Optical Cable designed for SFP28 ports supporting 25Gb/s links. The cable provides a direct optical connection between compatible network devices, reducing electromagnetic interference and simplifying short-reach interconnects in data centers, switches and servers. It is intended for compact plug-and-play deployment and consumes less power than many copper alternatives, making it suitable for high-density top-of-rack and server-to-switch connections where space and signal integrity matter.

Advantages

The Active Optical Cable delivers 25Gb/s per lane transmission over a 2 m duplex optical link with low insertion loss and immunity to EMI, enabling stable high-speed links in congested rack environments. As a factory-terminated optical assembly it eliminates the need for separate transceivers and fiber patch cords for short-reach connections, simplifying inventory and installation. The cable’s small form factor and low power characteristics help reduce thermal load and cabling congestion in data center racks.

Suitable for

• Top-of-rack switch to server uplinks
• High-speed server interconnects in data centers
• Short-reach connections between SFP28-enabled switches and network cards
• Environments with electromagnetic interference where optical links are preferred

Key specifications

• Connector type: SFP28 duplex on both ends
• Data rate: 25 Gb/s per channel (25Gb/s link)
• Length: 2 meters
• Medium: Active optical cable (factory-terminated)
• Power profile: low-power design compared with equivalent copper direct-attach cables
• Compatibility: designed for SFP28 ports supporting 25Gb/s links

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 according to vendor guidelines and that firmware or driver compatibility for SFP28 modules is met. Once connected, verify link status on both devices and monitor link integrity via device management tools. No additional transceivers or separate fiber patching is required for the stated short-reach use.

Recommendations

For reliable operation, avoid sharp bends and excessive tensile stress on the optical cable; maintain the minimum bend radius specified by the manufacturer. Use in SFP28 ports confirmed to support 25Gb/s links and check device compatibility notes before deployment. Keep connectors clean and dust-free when not in use and perform visual inspection or cleaning procedures recommended by equipment vendors.
