CBO AOC SFP28 BlueOptics BO272703Q3M 3M Passive 25Gbps SFP28 Active Optical Cable 3 m

The CBO AOC SFP28 BlueOptics BO272703Q3M 3M Passive is a 3-metre active optical cable designed for 25Gbps short-reach links between compatible network devices. Intended for direct-attach connections, this SFP28 AOC provides a single-cable solution for connecting servers, switches and storage systems with straightforward installation and predictable performance. The cable integrates SFP28 transceiver interfaces at both ends and is optimized for low-latency, high-bandwidth traffic in modern data centre and enterprise networking environments.

Advantages

This active optical cable delivers 25Gbps full-duplex bandwidth over a 3 m reach while eliminating the need for separate transceivers and patch fibre, which simplifies rack cabling and reduces component count. The integrated design ensures low insertion loss and consistent signal integrity across the link. Being a passive AOC model for short distances, it supports reliable, power-efficient operation and minimises latency for demanding applications such as server interconnects and switch stacking.

Suitable for

• Server-to-switch and switch-to-switch connections inside racks or between adjacent racks
• Top-of-rack and end-of-row high-speed links in data centres
• High-performance storage area network (SAN) connectivity
• Low-latency applications such as virtualization hosts and clustered compute nodes

Key specifications

• Data rate: 25 Gbps full-duplex
• Connector type: SFP28 form factor at both ends
• Cable type: Active optical cable (AOC)
• Length: 3 metres
• Reach: Short-reach, designed for intra-rack and adjacent-rack links
• Latency: Low-latency design suitable for high-throughput environments
• Compatibility: Designed for use with devices that accept SFP28 AOC modules

How to use

Install the AOC by inserting each SFP28 connector into the compatible SFP28 port on the devices to be connected. Ensure that both devices support 25Gbps SFP28 AOC connections and that ports are powered and enabled. No separate transceivers or external fibre patching are required. Once seated, the link should be negotiated automatically; verify link status and speed through the devices' management interfaces and apply any required configuration such as port speed or VLAN settings.

Recommendations

For reliable operation, avoid tight bends and excessive tensile stress on the cable, maintain recommended bend radius, and route the cable to prevent sharp kinks. Use this 3 m AOC for short-reach connections within racks or between adjacent racks and verify firmware and compatibility notes of networking equipment when deploying in mixed-vendor environments.
