Differences and advantages between 10G DAC and SFP + optical modules
The development of Artificial intelligence and the Internet poses new challenges to data center capacity expansion. Technology and cost often collide with sparks. To achieve high density and high capacity, cost control should be controlled at the same time. Reasonable wiring is very important. We can choose high-speed cable and optical module & patch cord combination when wiring, then how to choose these two products in the actual scene? What are the differences between them and what are the advantages? Let's learn together!
As a transmission medium, 10G SFP + DAC and 10G optical module can be chosen, what are the differences between them?
The 10G DAC connects two switches via copper cables, and the SFP + modules connect two switches by connecting to patch cords.
10G DAC for short-distance transmission, the farthest distance is 15M, often be used in the engine room.
SFP + modules for long distances transmission, the longest of single fiber is 80KM, dual fiber is 100KM.
10G SFP + DAC advantages:
10G DAC is a copper cable with SFP + connectors at both ends, which is lower in cost than 10G optical module.
10G DAC wiring is more flexible, transmission distance up to 15 meters, the operation difficulty is lower in the actual construction process;
10G DAC wiring saves connection equipment and does not need to use a wire rack. Servers and network equipment can be directly connected to the TOR switch, this saves the cost of input indirectly.
10G SFP + optical module advantages:
If the vertical distance of the cabling does not exceed the cabinet, can connect with a 10G DAC. When a TOR switch is connected to a network switch, if the distance is greater than 15M, select multimode fiber and optical module to achieve, usually use OM3/OM4 LC patch cord and 10G SFP + optical module. In other words, 10G SFP+ optical module is more widely used in long distance transmission..
