With the widespread use of 40G Ethernet, in order to further achieve higher bandwidth and throughput requirements, 100G has become the trend of data transmission. The 100G QSFP28 series of products’ attention is creasing in the 2016 years of the United States optical fiber communication exhibition and seminar (OFC), while the subsequent 100G QSFP28 standard announcement also means that 10G / 40G to 100G network migration has added a new s solution. This article will provide several common 100G QSFP28 high-speed cable solutions and several popular products for your choice.

Solution 1: 100G QSFP28 to QSFP28 high-speed cable

100G QSFP28 high-speed cable, direct use of a cable to a QSFP28 interface and another QSFP28 interface connection for short-distance QSFP28 devices between the stack and set, has a great cost advantage. 100G QSFP28 to QSFP28 high-speed cable has four transmission channels, because the transmission is 100G signal, so this high-speed cable will be 100G electrical signal is divided into 4-way electrical signal to 4 * 25G electrical signal transmission. Compared to the previous 10 10Gbps speed channel superposition can be used to achieve 100G solution, it has more convenient operation, higher transmission efficiency advantages

Solution 2: 100G QSFP28 to 4 * SFP28 high speed cable

Similar with 100G QSFP28 to QSFP28 high-speed cable, 100G QSFP28 to 4 SFP28 high-speed cable also has four transmission channels, each channel transmission rate up to 25Gbps. The difference is 100G QSFP28 to 4 * SFP28 high-speed cable with four fan-out cable, a QSFP28 interface and four SFP28 interface connected, which makes high-speed cable is no longer limited to their own single type of product between the connection , Greatly improving the flexibility of engineering applications.
