As you can see the figures above, 25G/100G Data Center is already coming and will finally overpass others in next 3 years.
Why turn to 25G/100G instead of 40G/100G?
That’s because, comparing to 40G/100G, 25G/100G is more high-performed and cost-effective.
Even though 40G is faster then 25G, but current 40G is achieved through 4x10G, whereas 25G is single lane 1x25G. Now for 25G technology, 100G can be achieved by 4×25 rather than 10×10. So 25G can create higher bandwidth and more scalability .
You may doubt how about upgrading from 10G cause 10G is most used now. Then, we have to know something about 25G optical transceiver—SFP28.
SFP28, as the enhanced version of SFP+, is designed for 25G signal transmission. SFP28 utilizes the same form factor as SFP+, but the electrical interface is upgraded to handle 25Gbps per lane. Since its transmission rate can reach up to 28Gbps, it is so called as SFP28.
As SFP28 adopts the same form factor as SFP+, SFP28 can connect with SFP+ ports and SFP+ can also connect with SFP28 ports. SFP28 is compatible with existing data center fiber cabling.
Thus, 25G/100G can reduce the cost of re-architecture data centers and creates higher bandwidth during migration, 25G/100G is the trend!
