With the trend of higher transmission rate, higher density and lower power consumption, 200G Ethernet has become the favorite in the market, and 200G optical module, 200G AOC and 200G DAC are the most important parts. Now there are a variety of 200g data center optical interconnection solutions on the market, including 200G optical module, 200G AOC, 200G DAC. The following etu-link of Yitian optical communication will introduce a short distance interconnection scheme of 200G data center.

Introduction of 200G QSFP56 high speed cable

1、200G QSFP56 DAC

The 200G QSFP56 DAC high-speed cable adopts 200G QSFP56 module components at both ends, with the longest cable length of 5m, supporting I2C double wire serial interface, easy to control, low power, low crosstalk and other characteristics. QSFP56 cable components are optimized to reduce crosstalk and plug loss, provide excellent signal integrity and fully meet the next generation Ethernet and Infiniband standards.

2、200G QSFP56 to 2x100G QSFP28 DAC

One end of the 200G QSFP56 to 2x100G QSFP28 DAC high-speed cable is connected with one 200G QSFP56 module and the other end is connected with two 100G QSFP28 modules. The longest cable length is 3M. It is mainly used to connect optical fiber network devices and provide high-speed long-distance connection capability.

3、200G QSFP56 to 4x50G SFP56 DAC

One end of the 200G QSFP56 to 4x50G SFP56 DAC high-speed cable is connected with one 200G QSFP56 module and the other end is connected with four 50G SFP56 modules. The maximum length of the cable is 3M. It is mainly used to connect the 50GB / s server to the TOR switch.

Advantages of 200G QSFP56 high speed cable of ETU-LINK

In the short distance (1-5m) equipment interconnection of 200G data center, using 200G QSFP56 DAC high-speed cable has more price advantages than 200G AOC.

Finally, in the short-distance transmission scheme of 200G Ethernet data center, based on the factors such as wiring cost and power consumption, etc., ETU-LINK recommends that we choose 200G DAC high-speed cable. At present, 200G QSFP56 DAC high-speed cable is mainly used for the interconnection of computer data center and cloud server.
