The market prospects of 25G and 2.5G Ethernet are generally promising
Recently, Dell'Oro released the latest survey report for IT fields such as telecommunications, networks and data centers, pointing out that cloud data center Ethernet switches will accelerate the evolution to 25Gbps in the next five years, while enterprise (campus) campus Ethernet switches will also accelerate their evolution to 2.5Gbps
25G and 2.5G Ethernet are promising
"In the next few years, Ethernet switches in all fields will face changes and evolve towards faster speeds and more functions."
Alan Weckel, Vice President of Dell'Oro Group, said: "Cloud computing will drive at least three rounds of product upgrades in data centers. Initially, 10G will be upgraded to 40G, and now and in the next few years it will be upgraded to 25G, followed by a smooth evolution to 100G.
"
Alan Weckel also said that currently enterprise (campus) campuses are bidding farewell to the gigabit access (1Gbps) era and evolving towards 2.5/5Gbps, mainly to solve the upward pressure brought by the increase in 11acAP bandwidth. Currently, there are Many enterprise customers have decided to upgrade to 2.5G Ethernet
According to the report, in the next five years, the revenue sources and growth of the layer 2 and 3 Ethernet markets will come from 25Gbps and 100Gbps products, while 10Gbps and 40Gbps will decline significantly.

So much has been introduced, so what is 25G Ethernet or 2.5G Ethernet?
25G Ethernet is the same as the 1G/10G Ethernet we are familiar with. It is an Ethernet speed standard, but it breaks the traditional 10-fold evolution pace of Ethernet.
< p>Because the current 10G Ethernet speed standard can no longer meet the high bandwidth requirements, and 100G is too large, expensive and wasteful, the 25G (and 50G) Ethernet standards came into being.It is worth mentioning that 25Gbps and 50Gbps per channel technology are still the future 100Gbps (4*25Gbps) and 400Gbps (8*50Gbps) Ethernet standards Therefore, the industry generally hopes to use this transmission rate to replace the existing 10Gbps rate
Of course, in addition to 25G and 50G Ethernet, 2.5GE and 5GE Ethernet Standards have also attracted much attention.
As mentioned above, with the popularity of 11acAP, the previous 1G Ethernet can no longer meet the bandwidth demand from WLAN, and the 10G standard is not suitable for cabling. It is practical, so the industry has begun to pay attention to 2.5GE and 5GE Ethernet and actively promote their development.
