Active Optical Cable BlueOptics SFP28 25GBASE-SR Ethernet/Infiniband, 50 m

Active Optical Cable BlueOptics SFP28 25GBASE-SR Ethernet/Infiniband, 50 m is a factory-terminated SFP28 AOC designed for short-reach 25 Gbit/s links in data centers, network switches and server interconnects. The cable integrates SFP28 transceivers and a multimode fiber connection to provide a 50 meter optical link without separate transceiver modules. It is intended for high-speed Ethernet and InfiniBand environments where low latency, reduced electromagnetic interference and tidy cabling are required.

Advantages

The Active Optical Cable offers a compact, integrated solution combining transceivers and fiber in a single assembly, eliminating separate module installation and reducing inventory complexity. Using multimode fiber and SFP28 connectivity, it supports 25 Gbit/s data rates with low latency suitable for performance-sensitive applications. Optical transmission removes conductive cabling between devices, lowering susceptibility to electromagnetic interference and improving signal integrity over the 50 m reach. Factory termination and tested optics provide predictable performance and simplified deployment.

Suitable for

• 25 Gbit/s Ethernet uplinks between switches and servers
• Short-reach InfiniBand host and switch connections
• High-density data center top-of-rack and spine interconnects
• Low-latency, low-EMI environments where copper cabling is undesirable

Key specifications

• Connector type: SFP28 integrated optical transceivers
• Data rate: 25 Gbit/s
• Reach: 50 metres over multimode fiber
• Optical standard: 25GBASE-SR
• Application: Ethernet and InfiniBand short-reach links
• Form factor: Active Optical Cable (factory-terminated)

How to use

Install the Active Optical Cable by inserting each SFP28 end into the corresponding SFP28 port on switches, servers or adapters until the latch engages. No separate transceiver modules or fiber connectors are required. Verify link status on connected devices and confirm the interface negotiates the expected 25 Gbit/s mode. For best results, route the cable to avoid tight bends and physical strain on the connector housings. Diagnostics and link indicators on host devices can be used to confirm proper operation.

Usage recommendations

Use this AOC for short-reach 25 Gbit/s connections in data center racks and between adjacent equipment racks. Maintain minimum bend radii and avoid sharp kinks; ensure ports and cable ends remain free of dust and contaminants when inserting. For long-term reliability, avoid repeated hot-plug cycles and follow device vendor guidance on supported AOC compatibility.
