Supporting all major SFP+ modules and cables (except Cisco), it ensures minimal signal loss and easy plug-and-play installation. Ideal for professionals seeking smooth migration to 40G Ethernet while maximizing existing hardware investments. ## Description Specifications: The 10Gtek QSFP to SFP Adapter (QSA) Module offers 10 Gigabit Ethernet connectivity for QSFP-only platforms.It allows smooth and cost-effective migration to 40 Gigabit Ethernet by providing an option to use lower-speed SFP modules in empty QSFP ports or when the other end of the network is running at lower speeds. The QSA Module interoperates with all major optical modules and direct attached copper cable vendors. Its design assures minimum loss on the conversion path between the QSFP cage and the SFP receptacle. The high-speed data channel of the SFP receptacle is connected to lane 1 of the QSFP connector. The three remaining channels on the QSFP connector are not connected. With this adapter, you have the flexibility to use any SFP module or cable to connect to a lower-speed port on the other end of the network. This flexibility allows a cost-effective transition to 40 Gigabit Ethernet by maximizing the use of high-density 40 Gigabit Ethernet QSFP platforms. This adapter supports all SFP optics and cable reaches. Compatible Switch Models and SFP Modules. Features: Trouble-free installation and network bring-up Compliant to industry standards: SFF-8665 Compliant to industry standards: SFF-8432 Precision process control for minimization of pair-to-pair skew 1 independent duplex channels operating at 10Gbps data rates All-metal housing for superior EMI performance100ohm differential impedance system Operating case temperature: -20 to 85℃ Low insertion lossLow crosstalk Secure latching mechanism RoHS compliant Compatible with RoHS Single 3.3V power supply Applications: Low EMI radiation Switches, servers and routers Telecommunication and wireless infrastructure Test and measurement equipment Networked storage systems Data Center networks Storage area networks ## Features - 【Wide Compatibility】This adapter supports all SFP+ optics and cable (except Cisco) reaches, such as 10G-SR, 10G-LR, 10G-ER, 10G-ZR, 10G SFP+ Copper Cable and 10G SFP+ Active Optical Cable. I2C read port information comes from SFP port module, not QSA Module. - 【Smooth Speed Migration】10Gtek QSA adapter Module offers 10 Gigabit Ethernet connectivity for QSFP-only platforms. It allows smooth and cost-effective migration to 40 Gigabit Ethernet by providing an option to use lower-speed. - 【Convenient and Flexible Use】With QSA adapter, you can flexibly use any SFP+ module or cable to connect to a lower-speed port on the other end of the network with low insertion loss and crosstalk. Plug and play, without any setup. - 【QSA vs QSFP Breakout Cable】Not all the 40G cards and switches can be split into 4x 10Gb mode, for example, the Mellanox QSFP cards do not support the QSFP to SFP+ breakout, but they support QSA. And QSA can be used for longer transmission distances than QSFP Breakout Cable. - 【What You Get】1x cost-effective QSFP+ to SFP+ QSA adapter. 10Gtek is a manufacturer of DAC/Transceiver/AOC/NIC/Media Converter, customized service also is available. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07QH5DNLT | | Best Sellers Rank | #59,462 in Computers ( See Top 100 in Computers ) #90 in Network Transceivers | | Item model number | WADQS-10(1pc) | | Manufacturer | 10Gtek | | Package Dimensions | 16.41 x 7.19 x 2.11 cm; 59 g | ## Images ![QSA Adapter - 40G QSFP+ to 10G SFP+ Converter Module for Mellanox MAM1Q00A-QSA-SP, Dell 407-BBRO, Juniper, Arista, Extreme and More. - Image 1](https://m.media-amazon.com/images/I/51GAVnOXnkL.jpg) ## Available Options This product comes in different **Color, Size, Number Of Items** options. ## Frequently Bought Together - 10Gtek QSA Adapter - 40G QSFP+ to 10G SFP+ Converter Module for Mellanox MAM1Q00A-QSA-SP, Dell 407-BBRO, Nokia 474938A, Juniper, Arista, H3C, Extreme and More - 10Gtek 10GBase-T SFP+ to RJ-45 Transceiver, 10Gbe SFP+ Copper Ethernet CAT.6a Module, up to 30-Meter, for Cisco SFP-10G-T-S, Meraki, Ubiquiti UniFi UF-RJ45-10G, Fortinet, Netgear AXM765, Pack of 8 - ipolex 40G QSFP+ to 10G SFP+ QSA Adapter Converter Module for Mellanox MAM1Q00A-QSA, Dell 407-BBRO, Juniper, Arista, Extreme, Nokia 474938A, H3C and More, Support All SFP+ Modules and Cables Reach --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/387491863-qsa-adapter-40g-qsfp-to-10g-sfp-converter-module-mellanox](https://www.desertcart.us/products/387491863-qsa-adapter-40g-qsfp-to-10g-sfp-converter-module-mellanox) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-16*
