Differences and advantages between 10g DAC and SFP+Optical module.cicso sfp transceivers module wholesale

The development of artificial intelligence and the Internet of Things has posed new challenges to the capacity expansion of data centers. Sparks often arise between technology and cost. In order to achieve high density and capacity, cost factors also need to be controlled. Reasonable wiring is very important. When wiring, we can choose the combination of high-speed cable and Optical module jumper. How to choose these two products in actual scenarios? What are the differences and advantages between them? Let's learn together!

The transmission medium can be 10g SFP+DAC and 10g Optical module. What is the difference between them?

The 10g DAC connects the two switches through copper cables, and the SFP+Optical module connects the two switches through jumpers.

10g DAC short distance transmission, with a maximum distance of 15m, mainly used in computer rooms.

SFP+modules can be used over long distances. At present, the longest single fiber is 80km, and the longest dual fiber is 100km.

Advantages of 10G SFP+DAC:

10g DAC is a copper cable with SFP+connectors at both ends, and its cost is lower than that of 10g Optical module;

10g DAC wiring is more flexible, with a transmission distance of up to 15m, reducing the difficulty of operation during the actual construction process;

10g DAC wiring saves connection equipment and eliminates the need for patch panels. Servers and network devices can be directly connected to the tor switch, indirectly saving investment costs
