There are two types of 10G SFP+cables: 10G SFP+DAC and 10G SFP+AOC. They and 10G SFP+optical modules are commonly used optical devices for data center top-of-rack (ToR) cabling, which are used to connect small access switches and servers. Among them, 10G SFP+DAC is used to realize short-distance connection in the rack, while 10G SFP+AOC is applicable to the connection between the racks of ToR and EoR switches. So how to select the appropriate 10G SFP+cable according to different network deployment requirements? BuyDacable Co., Ltd will give a specific answer to this question through this article.
10G SFP+DAC and 10G SFP+AOC can be used to connect servers to switches or switches to switches.
The main purpose of 10G SFP+DAC is to connect the switch/server to the switch in or near the rack. In other words, these 10G direct connection cables can be used as an alternative to the ToR (rack top) interconnection or 10GbE switch stacking between the 10G ToR switch and the server. Since 10G SFP+DAC usually supports a link length of 7 m, with low power consumption, low latency and low cost, this option is the ideal choice for this short-distance server-to-switch connection.
10G SFP+AOC supports a link length of up to 100m, and is a low-cost solution to replace optical modules, so it is usually used for connecting switches and switches.. 10G SFP+AOC is usually used in multiple locations in the data center, such as ToR, EoR (end of line) and MoR (middle of line). Like DAC, all servers are connected to the rack top Ethernet switch. Each server has one or two Ethernet connections to the switch. These can be repaired with AOC cables.
More importantly, the utilization of 10G AOC in the data center can also be realized in several major networking areas such as Spine, Leaf or Core switching areas.
If you need to realize the connection between servers and switches within 7m, we recommend you choose 10G SFP+DAC. If you need to connect two switches and the link length is within 100m or you need a cost-effective 10G SFP+cable solution, then 10G SFP+AOC may be more suitable for you.
BuyDacable Co., Ltd. can provide customized services for the length and brand of 10G DAC and AOC, and both ends of the cable can be customized to different brands, and can also ensure full compatibility with major brands such as Cisco, DELL and Intel.
