To be able to handle ever-increasing data loads, the industry's largest long-distance cloud companies have moved to 100G Ethernet along with other core network data center operators.

However, most operators believe that for server connections, their workloads only need incremental improvements on the 10G network.

1. Data Center

When the server speed starts to migrate from 10G to higher speed, the current 10GE optical fiber and other basic components have already been built. During the upgrade, switching to 40GE will cause a lot of resource investment, and the original investment cannot be protected. , but 25GE is fully compatible with the relevant physical standards of 10GE, which can achieve fast switching and protect the original investment.Therefore, from the perspective of resource investment and cost, 25GE will be the best choice for server upgrades. Optical interconnect products for 25G servers include 25G SFP28 optical modules, 25G DAC high-speed cables, and 25G AOC active optical cables.

1. 5G base station

Whether a 5G base station uses a 25G optical module or a 100G optical module depends on the interface protocol. In the case of the same transmission content, the CPRI protocol is used, and the effect is good, but the rate of the optical module must be large enough, and the eCPRI protocol is used. Poor, but the optical module is cheap and can use low speed.Different operators choose different protocols and data compression ratios. Choosing CPRI has less distortion and better effect, but needs to choose higher rate optical modules.

The introduction of new 5G service features, the innovation and changes of the wireless access network structure and core network architecture have provided opportunities for a new round of rapid development of bearer technology. In terms of data centers, the existing 100G standard network system consists of four links. The bandwidth of each channel is 25Gbps, making it easier for network operators to expand their data centers.
