Nowadays, under the rapid development of big data, artificial intelligence, Internet of Things and other network technologies, 10G network can no longer cope with the future traffic demand. In order to meet the upgrade of 10G network, and based on the low cost and high efficiency factors, 40G QSFP+ to 10G SFP+ DAC branch high-speed cable has become the preferred interconnection scheme for the short-distance 10G upgrade of 40G network.In this article, ETU-LINK Technology (ETU-LINK) will introduce the 40G QSFP+ to 10G SFP+ DAC branch high-speed cable.

We all know that DAC direct attach cables are mainly used for the connection between servers in data center racks and the connection between servers and switches (the height of a standard cabinet does not exceed 3 meters) or the interconnection of equipment in adjacent racks. More servers accessing high-speed switches can help reduce the number of low-speed switches and save space.

The 40G QSFP+ to 10G SFP+ DAC branch high-speed cable complies with the latest SFP+/QSFP MSA (multi-source agreement), which can build a bridge between 10G and 40G switches/host adapters. The maximum transmission rate of the SFP+ module of the 40G branch high-speed cable can be Up to 10.3125Gbps (aggregate 40Gbps). In addition, high-wire cables can reduce power budgets compared to optical fibers.

40G QSFP+ to 10G SFP+ DAC branch high-speed cable can not only realize the interconnection of 10G switch and 40G switch and the interconnection of server and switch (the interconnection of QSFP+ port of switch and SFP+ port of server network card NIC/HBA), but also the connection of switch and The interconnection of converters (transmission relays) achieves the purpose of interconnection with remote network equipment.

In addition to 40G QSFP+ to 10G SFP+ branch cables, 40G DAC high-speed cables also have 40G QSFP+ to QSFP+ DAC, which can be used for short-distance stacking and assembly between devices with QSFP ports. The new generation of 40G/100G data center takes a long time to prepare, so upgrading from the current 10G network is the most cost-effective way.
