10G DAC Direct Attach Cable and SFP+ module
493 2022-12-07
The development of artificial intelligence and the Internet puts forward new challenges for the expansion of data centers. It often collides between technology and costs. While achieving high density and high capacity, it is necessary to control cost factors. Reasonable wiring is very important. At this time, we can choose the combination of high -speed cables and light modules. So how should we choose these two products in the actual scene? What are the differences and advantages between them? Let‘s learn together!
As a transmission medium, 10G SFP+ DAC and 10G SFP+ modules can be selected. What are the differences between the two?
10G DAC connects two switches through copper cables, and the SFP+light module connects two switches by connecting with jumper.
10G DAC short distance transmission, 15m long distance, mostly used in the computer room.
The SFP+module can be long -distance. The single fiber is currently 80km, and the fiber fiber is 100km.
10G SFP+ DAC advantage:
10G DAC is a copper cable designed with SFP+connectors at both ends. Compared with the 10G light module, the cost is lower;
The flexibility of 10G DAC wiring is higher, the transmission distance can reach 15 meters, and it is more difficult to operate in the actual construction process;
10G DAC wiring saves connection devices. It does not need to use wiring frames. The server and network devices can be directly connected to the TOR switch. This indirectly saves the input cost.


10G SFP+light module advantage:
If the vertical distance of the wiring does not exceed the cabinet, you can use 10G DAC to connect at this time. When the TOR switch is connected to the network switch, if the distance is greater than 15m, select multi -mode fiber and optical modules to achieve it. Generally, OM3/OM4 LC fiber fiber jump line and 10G SFP+optical module are usually used. In other words, the 10G SFP+light module is widely used in long distance transmission.


HTFUTURE provides data center interconnect high -speed direct connection solutions, especially the solution of 10G 10,000 -meabytes of SFP+SFP+high -speed cables, which not only reduces power consumption, but also increases the scalability of the network.
