Product Details
✓【Broad Compatibility with Mellanox SFP28 Devices】Our QSA adapter is fully compatible with all Mellanox SFP28 optics and various cable lengths, including popular models like MMA2P00-AS, MMA2L20-AR, SFP28 Passive Copper Cables, and SFP28 Active Optical Cables. It’s important to note that I2C port information is retrieved from the SFP28 port module, not the QSA Module itself.
✓【Seamless Speed Migration & Cost Savings】QSA Adapter Module enables 25 Gigabit Ethernet (GbE) connectivity on platforms that only support QSFP28. It provides a smooth, cost-efficient transition to 100 Gigabit Ethernet by allowing the use of lower-speed components, eliminating the need for expensive hardware upgrades all at once.
✓【Flexible & Hassle-Free Usage】With this QSA adapter, you can freely use any SFP28 module or cable to connect to a lower-speed port on the opposite end of your network. It features low insertion loss and crosstalk for stable signal transmission, and its plug-and-play design requires no complicated setup or configuration—simply connect and go.
✓【QSA vs. QSFP28 Breakout Cable: Key Differences】Not all 100G cards and switches support splitting into 4 x 25 Gb mode. For example, Mellanox QSFP28 cards do not support QSFP28-to-SFP28 breakout, but they are fully compatible with QSA adapters. Moreover, QSA adapters support longer transmission distances than QSFP28 Breakout Cables, making them more versatile for diverse network setups.
✓【Package Inclusion】You will receive 1 x high-cost-effective QSFP28 to SFP28 QSA adapter, engineered to deliver reliable performance while keeping your budget in check.
