Its 25GbE SFP28 interfaces are backward compatible with 10GbE SFP+/1GbE SFP interfaces, and the 100GbE QSFP28 interface can be uplinked to 100GbE+ core switches, or connected to 100GbE+ servers/NAS directly. AOC-CX766003N-SQ0. The table below is a Cisco 40G QSFP+ compatibility matrix list, which is collected through Cisco optics-to-device compatibility matrix tool. I wanted to confirm with someone who has experience with 'QSFP28/SFP28' type cables in Mellanox & Brocade equipment (switches & cards), before I spend some real money (DAC type). QSFP28 Backward Compatibility QSFP28 Wiki. QSFP28 has the same factor and size as QSFP. The puzzles of transceiver compatibility often focus on optics-to-device or optics-to-optics interoperability. To connect a 10G device to a device with QSFP28 ports, use a QSFP-to-SFP+. This solution is useful when connecting: On the 100GbE side there a switch. Cisco QSFP-100G-AOC30M Compatible 100G QSFP28 Active Optical Cable. S. 2 modules. This basically means that systems (host devices) which are designed with QSFP-DD port are backward compatible with QSFP56 and QSFP28 form factor transceivers. 2. Both of them can be used in 100G networks, but the SFP28 is applied in the form of QSFP28 to the SFP28 breakout solution. Both of them can be used in 100G networks, but the SFP28 is applied in the form of QSFP28 to SFP28 breakout cables. One of the most significant features of QSFP-DD is backward compatibility. Get a quote via sales@qsfptek. Systems designed with QSFP-DD ports are backwards compatible to support existing QSFP+, QSFP28, and QSFP56 modules. I've been repeating that 25gbe is backwards compatible with 10gbe for years now. com and simply connect the two. 1 IOS-XR. The Differences: SFP+ vs. Note that the QSFP/QSFP+/QSFP28/QSFP56 are designed to be electrically backward compatible with SFP/SFP+/SFP28 or SFP56 respectively. QSFP+ is for 40G. 0, v2. it backward compatible with existing SFP+ I/O ports. 900B 1000B 1200B 2000B. When implementing a SmartFabric, two DAC - Q28DD-200G-xM OR AOC -Q28DD-200G-xMBackward compatibility. Speed that supports both. 3ba-2010 standard. Backwards Compatibility. We are trying to do QSFP28 to SFP28 breakout cables to connect, right now, Netapp equipment that as of now have QSFP ports on the switch end and SFP+ on the node end. SR4. Lastly, there are several types of QSFP28 connector:. 400G QSFP-DD is also more flexible with regard to backward compatibility. It also simplifies the development of interoperability specifications and systems due to the fact that it is backward compatible and gives an easier upgrade path from an existing 10G TOR server. 100GbE. 3 40G QSFP+. I have only an SFP router presently. Backward compatibility: allowing the QSFP-DD to support existing QSFP modules (such as QSFP+, QSFP28, QSFP56, etc. Given that OSFP has a bigger size, it cannot directly compatible with QSFP. state-of-the-art data plane programmability, backward compatible 25GbE server port connections, 100GbE uplinks, storage optimized architecture, and a broad range of functionality to meet the growing. 100G-QSFP28-80 Transceiver is fully compliant to QSFP28 Multi Source Agreement (MSA) and IEEE 802.
