SFP28 Aktívny optický kábel CBO SFP28-AOC-20M 20 m

SFP28-AOC-20M is a 20-meter active optical cable by BlueOptics designed to deliver 25 Gbps connectivity between compatible SFP28 ports. The cable integrates optical transceivers into a single plug-and-play assembly, providing a direct fiber connection without separate modules. It is intended for short-reach, high-density interconnects where low latency, electrical isolation and simplified cabling are required, such as server-to-switch and switch-to-switch links in data centers and high-performance computing racks.

Advantages

The BlueOptics SFP28 active optical cable offers a compact, all-in-one solution that eliminates the need for discrete transceivers and separate fiber patch cords. As an active cable it supports the full 25 Gbps line rate while maintaining low latency and signal integrity over 20 meters. Electrical isolation inherent to optical links reduces ground loop and EMI concerns, and the integrated design simplifies inventory and installation compared with separate pluggable modules and patching. The single-assembly format reduces connector count and helps maintain high port density in switch and server environments.

Suitable for

• Server-to-switch uplinks in data centers
• Switch-to-switch connections in aggregation and spine-leaf architectures
• High-performance computing clusters and storage networks
• Short-reach interconnects where 25 Gbps bandwidth and low latency are required

Key specifications

• Electrical isolation: Optical link provides galvanic isolation between devices
• Use environment: Designed for data center and enterprise networking racks

How to use

Install by inserting each SFP28 connector into the corresponding SFP28 cage on the devices to be linked. Ensure both ends are fully seated and that devices are powered and configured to use the 25 Gbps port. The cable is plug-and-play in most environments, with active electronics negotiating link parameters automatically. Avoid excessive bending and ensure proper cable routing in rack channels or cable management trays to maintain optical performance. Follow device vendor instructions if the switch or server requires specific port settings or firmware support for active optical assemblies.

Recommendations

For reliable performance, route the cable within recommended bend radii and avoid tight kinks. Verify compatibility with the host device vendor if the network equipment has vendor-specific compatibility lists. Use the 20 m length for short- to medium-reach connections within data center pods or between adjacent racks to maintain low latency and high throughput.
