SFP28 Active Optical Cable

SFP28 Active Optical Cables provide high-speed, cost-effective, and reliable 25G connectivity for short-range data center and high-performance computing applications.

Key Features

High-Speed Data Transmission: SFP28 AOCs support data rates up to 25 Gbps for Ethernet and up to 28.05 Gbps for Fibre Channel applications, enabling fast and efficient data transfer within racks and across adjacent racks . Cable Lengths and Fiber Type: These cables are available in lengths ranging from 1 meter to 10 meters, using multimode fiber (MMF) with a nominal wavelength of 850 nm. They support link distances up to 70 meters on OM3 fiber and 100 meters on OM4 fiber . Form Factor and Compatibility: SFP28 AOCs use the SFP28 form factor, which is physically compatible with SFP and SFP+ ports. This allows for backward compatibility with existing 10G infrastructure while upgrading to 25G speeds . Standards Compliance: They are compliant with IEEE 802.3by and IEEE 802.3cc, as well as SFP28 MSA, SFF-8431, and SFF-8432 standards. This ensures interoperability with other IEEE-compliant 25G interfaces and high reliability . Electrical and Optical Interface: The electrical interface uses a 20-contact edge connector, while the optical interface is designed for short-range multimode fiber links. AOCs require BASE-R FEC or RS-FEC on host ports for optimal performance . Digital Diagnostics: Many SFP28 AOCs include digital diagnostic monitoring (DDM), providing real-time monitoring of transmitted/received power, bias current, supply voltage, and temperature. This helps maintain network reliability and simplifies troubleshooting . Environmental and Regulatory Compliance: These cables are RoHS compliant and meet Directive 2011/65/EU, ensuring safe and environmentally responsible operation . Applications: SFP28 AOCs are ideal for data center internal networks, high-performance computing, wireless networks, and metropolitan area networks, providing a cost-effective solution for short-range, high-bandwidth connectivity . In summary, SFP28 Active Optical Cables combine high-speed performance, short-range flexibility, backward compatibility, and diagnostic capabilities, making them a reliable choice for modern 25G network deployments .
