With the revolutionary progress of large-scale information system, cloud computing technology with its low-cost, convenient, high scalability features, provides a practical technical guarantee for the development of big data, Internet and artificial intelligence. Facing the requirements of high speed, high density, low cost and low power consumption in optical interconnection products of short distance data center, AOC active optical cable provides an excellent solution.

In recent years, AOC has been upgrading to a higher rate, and new products have been launched in 100G, 200G and even 400G AOC. Among them, 200G AOC is a popular product in recent years. Next, ETU-LINK will introduce this product to you.

200G QSFP28-DD AOC active optical cable introduction

1. The 200G QSFP28-AOC active optical cable adopts a hot-swappable QSFP-DD package with a wavelength of 850nm. The maximum transmission rate of the optical transceivers at both ends is 206.25Gb/s. It has 8 channels and the maximum transmission rate of each channel It is 25.7812Gb/s, and the cable length is optional from 1-100m. 200G QSFP28-DD AOC active optical cable is mainly used for short-distance data center 200G (2x100GBASE-SR4) Ethernet links.

2. 200G QSFP28-DD to 2x 100G QSFP28 AOC adopts 8-channel full duplex active optical cable, one end is connected with one 200G QSFP28-DD module, the other end is connected with two 100G QSFP28 modules, the maximum transmission rate is 206.25Gb/s, and the cable length is 1-100m optional. 200G QSFP28-DD to 100G QSFP28 AOC is mainly used for data center 200G to 2-way 100G (100GBASE-SR4) ethernet branch link.

3. The conversion from 200G QSFP28-DD to 4x 50G QSFP28 AOC adopts 8-channel full duplex active optical cable. One end is connected with one 200G QSFP28-DD module, and the other end is connected with four 50G QSFP28 modules. The maximum transmission rate is 206.25gb/s, and the cable length is 1-100m. The 200G QSFP28-DD to 50G QSFP28 AOC is widely used in data center 200G to 4-way 50G Ethernet branch link.

Advantages of 200G QSFP28-DD AOC active optical cable

1. Compared with 200G DAC cable

(1) In terms of weight and volume, the weight of 200G QSFP28-DD AOC active optical cable is only one fourth of that of direct copper cable, and its volume is about half of that of copper cable;

(2) In terms of transmission distance, the transmission distance of 200G QSFP28-DD AOC active optical cable is longer than that of copper cable (up to 100m);

(3) In terms of transmission bit error rate, the bit error rate of 200G QSFP28-DD AOC active optical cable transmission performance is lower.

2. Compared with 200G optical module

Due to the existence of non exposed optical interface, there is no problem of cleaning and pollution of optical interface. The stability and reliability of the system are greatly improved, which can greatly reduce the maintenance cost of the computer room.

The obvious advantages of 200G QSFP28-DD AOC active optical cable make it the focus of data center integrators and equipment manufacturers. In the R & D and production of active optical cable and other products, ETU-LINK has always been striving for improvement, using high-precision coupling and assembly process, with higher stability and lower power consumption, which will better assist the development of high-density and large-capacity data center and cloud computing network.
