## Description

10Gtek QSA Adapter - 40G QSFP+ to 10G SFP+ Converter Module for Mellanox MAM1Q00A-QSA-SP, Dell 407-BBRO, Juniper, Arista, Extreme and More.

## 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.
