1. 25G interface performance is 2.5 times that of 10G interface
2. 25G is 2.5 times the bandwidth of 10G
3.The price of 25G switches is not 2.5 times that of 10G switches
4. The 25G SFP28 optical module is based on SFP+ packaging, which can provide 25Gb/s error-free transmission and is compatible with the existing 10G infrastructure
The inevitability of upgrading from 10G to 25G
In summary, 25G is expected to relay 10G technology to become the infrastructure of future Ethernet. The specific reasons can be summarized as follows.
Data center transformation and upgrading rely on 25G
The development of data centers to 100G and 400G, together with the development of cloud computing, has promoted the upgrading of data center structures. Because 25G is backward compatible with 10G, upgrading from 10G to 25G can not only increase the access layer rate, but also save deployment and operating costs. From this point of view, it is a wise choice to deploy 25G at the access layer.
5G fronthaul infrastructure is inseparable from 25G
The 5G era will usher in a big explosion of data. Large bandwidth and high speed are the indispensable characteristics of fronthaul networks. However, 10G optical modules cannot meet these standards, so 25G/50G is used for transition. In terms of 5G fronthaul 25Gb/s optical modules, wavelength tunable optical modules are in the research stage, BiDi optical modules are in the sample stage, and other types of optical modules are mature. As 25G products become more and more complete, the migration from 10G to 25G will be gradually completed.
The superiority of 25G itself
The broad prospects of 25G cannot be underestimated. At this stage, manufacturers have invested in 25G product research and development, eager to get a share of the pie, so consumers can enjoy the lower product prices brought by competition. For example, although the performance of 25G optical modules is 2.5 times that of 10G optical modules, the price is not bad. Low cost is also one of the reasons why 25G has become the new 10G. Due to the above-mentioned significant advantages, the 25G solution is expected to become the new 10G.
