The tag of war between copper and fiber has been going on for years. If you believe that optical fiber is the replacement of copper, it is not true. Rather fiber and copper are more rivals to each other. And also, the latest advances in the technology of copper, fiber, and copper are almost the same. The difference of speed between the two is negligible. Decision makers of data centers and IT experts though prefer copper, but organizations with end-user still battle with which type serves the best. The same war is also going on SFP transceivers industries. Both fiber and copper SFP transceivers are available in a lot of places, such as on https://www.1000gig.com/, and when you are done with making your decision, you can go and purchase the one you would prefer by clicking on the link.
Difference between SFPs of Copper and Optical
Temperature for operating
There is no difference between SFPs of copper and fiber for the required temperature for operating. By default, both support temperature of 320F to 1580F, i.e., 00C to 700C. In general, the SFPs of copper runs much hotter compared to SFPs of fiber. The reason for a higher temperature in copper SFPs is that it consumes 1.05W of power, whereas, fiber SFPs consume 0.8W of power. If you run then on the same environment, the SFPs of fiber will run at 1040F, i.e., 400C, whereas SFPs of fiber will run at 1260F, i.e., 520C.
SFPs of copper is good for maximum cable distance of 100m; it can be used to interconnect switches and servers in shorter-length and horizontal backbone applications. SFPs of fiber has maximum cable distance of 120m so that it can be used for longer distances.
Fiber SFPs has better security compared to copper SFP. The reason is that fiber is a nonconductor of electricity and so it is resistant to lighting.
Mixing fiber and copper is the best solution for a data center. Their performance needs to have the speed of a rocket so that mixing will provide both solutions of scalability and manageability.
