Need More Than 10G?

What happens when 10G is no longer sufficient to meet your bandwidth requirements? Luckily there are many upgrade options available depending on what you anticipate as your future requirements.

Going to 40G or 100G

For many people the logical upgrade from 10G is to go to 40G or even 100G. With the majority of network equipment now equipped with QSFP+ ports for 40G or QSFP28 ports for 100G this is certainly a viable option and allows for much more room for growth in the future with capacity increased as much as 10x potentially.

The most likely challenge with this upgrade path though is the cost. While the cost of the QSFP+ and QSFP28 optical transceivers has been dropping steadily over the last few years, the bigger consideration is related to the cost of replacing other network gear (switches, routers, etc.) which may be considerable.

The 25G Alternative

A more cost effective upgrade path might be to go from 10G to 25G. Most network gear on the market today (switches, routers, etc.) offer versions which support both 10G and 25G in a cost effective way.

In addition, the availability of 10G/25G dual rate transceivers makes the transition from 10G to 25G even more cost effective and easier to plan for and manage as the same transceiver can be used with either a 10G SFP+ port or a 25G SFP28 port.

Which Option?

The short answer is that it depends. If you are looking for a solution that will provide significant bandwidth increase to meet your network requirements for the long term and are willing to make an investment, then the upgrade path towards 40G or even 100G is the way to go. If however you're looking for short term bandwidth relief and want to do it cost effectively, then 25G is more suitable.
