CBO InfiniBand active optical cable AOC-S-S-25G-3M-BO — 25G, 3 m

The CBO InfiniBand active optical cable AOC-S-S-25G-3M-BO is a 3-meter, 25G active optical link designed for short-range high-speed interconnects in data center environments. The cable uses electrical-to-optical conversion to reduce electromagnetic interference and preserve signal integrity across rack-to-rack and within-rack connections. Its InfiniBand-compatible active components enable reliable 25G throughput between switches, servers and storage systems where consistent low-latency performance is required.

Advantages

The active optical design minimizes electrical noise and crosstalk while extending reliable transmission distance compared with passive copper alternatives. At 25G data rate and 3 m length, the cable delivers stable high-bandwidth connectivity with reduced heat generation and lower susceptibility to electromagnetic interference. Its plug-and-play form factor simplifies deployment in dense rack environments and helps maintain signal quality for latency-sensitive applications.

Suitable for

• Short-range connections between switches in the same rack or adjacent racks
• Server-to-switch interconnects requiring 25G throughput
• Storage array links and backend fabrics in data centers
• Low-latency InfiniBand links for HPC or virtualization clusters

Key specifications

• Data rate: 25 Gbps
• Length: 3 m
• Cable type: active optical cable (AOC)
• Connector interface: InfiniBand-compatible twin-ax/optical modules (active)
• Use case: short-range, rack-to-rack and within-rack interconnects
• Signal conversion: electrical-to-optical conversion for reduced EMI

How to use

Install the cable by inserting the connectors into the corresponding InfiniBand ports on switches, servers or storage devices until they latch securely. Ensure both ends are connected to compatible ports supporting 25G operation and verify link status on the network devices. Avoid sharp bends and excessive pulling on the cable; maintain recommended bend radius and secure routing within cable management channels to preserve optical performance. No special configuration is usually required beyond verifying port speed and firmware compatibility on connected devices.

Recommendations

For reliable performance, use the cable in short-reach topologies within the same rack or between adjacent racks, keep connectors and ports free from dust, and check that connected hardware supports 25G InfiniBand operation. Avoid exposure to high temperatures and mechanical stress to maintain longevity of the active optical components.
