QSFP28 passive copper twinax cable (100G DAC 1to4 )assembly features eight differential copper pairs, providing four data transmission channels at speeds up to 28Gbps per channel, and meets 100G Ethernet,25G Ethernet, and InfiniBand Enhanced Data Rate(EDR) requirements. Available in a broad range of wire gages-from 26AWG through 30AWG-this 100G copper cable assembly features low insertion loss and low cross talk.
Designed for applications in the data center, networking, and telecommunications markets that require a high-speed, reliable cable assembly, this next-generation product shares the same mating interface with the QSFP+ form factor, making it backward compatible with existing QSFP ports.QSFP28 can be used with current 10G and 14G applications with a substantial signal integrity margin.

100G DAC is a DAC whose actual transmission rate can reach 100G. 100G DAC is a high-speed DAC. 100G DAC is generally used in 100G short-distance transmission network, plugged into a 100G optical port, and connected to another 100G optical port in the same rack or an adjacent rack. The price is much cheaper than the price of two 100G multimode optical transceiver s and a multimode jumper.
QSFP28 100G to 4*25G SFP28 Copper Twinax Cable is a 100G 1to4 DAC. 100G 1to4 DAC is a 100G QSFP28 transceiver connector connected to four 25G SFP28 transceiver connectors through copper cables. The method of use is to insert the 100G QSFP28 end into the 100G optical port, and the other four 25G SFP28 transceiver connectors are respectively inserted into the four 25G optical ports. 100G 1to4 DAC is generally a customized product with little demand.
