Import 200g Qsfp56 To Qsfp56 Dac Series — Buy in wholesale FOB from Supplier in China

The 200G QSFP56 TO QSFP56 DAC Series from Etu-link Technology Co., Ltd. is a passive direct attach copper cable assembly designed for 200-gigabit Ethernet and InfiniBand HDR connections. It operates on a 4x50G or 4x56G PAM-4 signal structure, though the listing also notes compatibility with 4x25G/4x28G configurations. The assembly is compliant with SFF-8636, IEEE802.3bj, and IEEE802.3cd standards, supporting I2C control and hot-plugging. Its design targets reduced crosstalk and plug loss for reliable signal integrity.

Passive DAC cables like this series use copper conductors rather than optical transceivers, making them a lower-power, lower-cost solution for short-distance, high-bandwidth links within a rack or between adjacent racks. The QSFP56 form factor is the current generation for 200G data rates. Typical industry specifications for these cables include support for 10G/40G/100G/200G Ethernet and InfiniBand speeds from SDR to HDR. The product description does not specify the exact cable lengths available or the gauge of the copper wiring, which are key details to confirm with the supplier.

These cables are sourced for deployment in data centers, cloud server environments, and high-performance computing clusters where switch-to-switch or switch-to-server connections require 200G bandwidth. Network engineers and infrastructure buyers use them to interconnect routers, switches, and concentrators. For procurement, the listing does not provide a minimum order quantity, unit price, or lead time, so these trade terms must be negotiated directly with Etu-link Technology. The supplier's address in Shenzhen, Guangdong, places them within China's primary electronics manufacturing hub.
