10G SFP+ cables: 10G SFP+DAC and 10G SFP+ AOC. Both of them and 10G SFP+ optical modules are common optical devices for data center overhead (ToR) wiring, which are used to connect small access switches and servers. Among them, 10G SFP+ DAC is used for short-distance connection within the frame, while 10G SFP+ AOC is suitable for connection between the frame of ToR and EoR switches.
10G SFP + DAC support 7meter of the link length, usually also has the advantages of the low power consumption and low latency, therefore become the choice of servers connected to the switch, and 10G SFP + AOC has support for 100meter of the link length, and is an alternative light module is low cost solution, so commonly used in switches and switch the connection between the.
If you need to achieve a connection between the server and the switch within 7m, it is recommended that you choose 10G SFP+DAC. If you need to connect two switches and the link length is 100 meters or you need a very cost-effective 10G SFP+ cable solution, then 10G SFP+ AOC may be more suitable for you.
