With the popularization of comprehensive structured cabling, fiber optic cables are widely used in various large and medium-sized date center as high-bandwidth and high-security data transmission medium. However, due to the high cost of fiber optic cable solutions, in some cases, copper cables still play an important role. For example, SFP+ DAC cable is a cost-effective solution for 10G data center short-distance transmission applications.

SFP+ DAC cables are widely used in the interconnection between 10G SFP+ Network Interface Card, the interconnection between 10G ToR switches and servers, and the stacking of 10G Ethernet switches.

Cabling Solution

In the currently popular spine and leaf topology, TOR switches are leaf switches and they are connected to the spine switches. In a 10G network, a 10G server is connected to a 10G switch through a 10G SFP+ DAC cable, Cat6a / Cat7, and a 10G SFP+ transceiver module. The 10G switch is connected as a leaf switch to a 40G spine switch.

SFP+ DAC cables are characterized by low loss, low power and low cost, and can meet the increasing cabling requirements of transmission rate, scalability and reliability. For the connection between the server and the switch within 10m, we recommended to choose SFP+ DAC cable.

Advantages of SFP+ DAC cable

SFP+ DAC cable is a copper cable with SFP+ connectors on both sides. The cabling solution of using 10G SFP+ DAC is more flexible and the transmission distance can reach 15m. It is easier to operate in the actual construction process and saves connection equipment. It can directly connect to TOR switches without using patch panels, servers and network equipment, which indirectly saves investment costs.

In Zebra cable, SFP+ DAC cable can reach 15m (Request Quote), which has the advantages of low power consumption and low latency. It has become an ideal choice for connecting servers and switches. For 10G SFP+ AOC cable, it can supports up to 100m, and is a low-cost solution to replace the transceiver module. It is usually used for the connection between switch and switch.
