The Cisco 25GBASE SFP28 portfolio provides a variety of high-density, low-power 25 Gigabit Ethernet connectivity options designed for data center and high-performance computing networks. These modules use the SFP28 form factor and comply with IEEE 802.3by and IEEE 802.3cc standards.
Key features and product types include:
- Copper Cables (25GBASE-CR1): Passive copper cables available in lengths from 1 meter to 5 meters (e.g., SFP-H25G-CU1M for 1 meter).
- Active Optical Cables (25GBASE-AOC): Active optical cables ranging from 1 meter to 10 meters (e.g., SFP-25G-AOC1M for 1 meter).
- Short Reach Modules (25GBASE-SR): SFP28 modules for multimode fiber (MMF).
- Long Reach Modules (10/25GBASE-LR): SFP28 modules for single-mode fiber (SMF), including industrial temperature variants.
- Bidirectional Modules: Such as 10/25GBASE-BR10 and 25GBASE-BR40 SFP28 bidirectional modules for SMF with industrial temperature support.
The portfolio supports interoperability with other IEEE-compliant 25G interfaces and is certified and tested on Cisco SFP28 ports for performance and reliability.
Examples of product IDs include:
- SFP-H25G-CU1M: 25GBASE-CR1 Copper Cable 1-meter
- SFP-25G-AOC1M: 25GBASE Active Optical Cable 1-meter
- SFP-25G-SR-S: 25GBASE-SR SFP28 Module for MMF
- SFP-10/25G-LR-S: 10/25GBASE-LR SFP28 Module for SMF
- SFP-25G-ER-I: 25GBASE-ER SFP28 Industrial Temperature Module for SMF
These modules and cables are used in various Cisco products such as UCS Fabric Interconnects, UCS Fabric Extenders, and Catalyst switches, supporting 25 Gigabit Ethernet connectivity with options for copper and optical media.
