What is SFP + DAC cable
Today, we will mainly talk about what SFP + DAC cable is, as well as its features and advantages.
What is SFP + DAC cable?
SFP + DAC is also called SFP + direct copper cable. SFP + is directly connected with a fixed length of cable, usually 1m, 2m, 3M, 5m or 7m. We use small cable and small SFP + module , which has the advantages of low power, low cost and low delay .
In the data center, copper cable is generally used to connect servers and storage area networks. The most common usage is direct attach copper cable (DAC), especially passive copper cable. Due to its low price and fast transmission speed, passive copper cable has become the best solution to realize short-distance transmission. For example, 40g qsfp + passive cable is one of the passive copper cables. Because of its low power consumption, high efficiency, low cost and low delay, it is widely used in 40g LAN, HPC and San for flexible cabling.
SFP+ DAC cable It is a low-cost technical scheme to replace 10G Optical module. It is widely used for short-distance high-speed interconnection of 10 Gigabit network cards, 10 Gigabit switches, 10 Gigabit devices, supercomputers, cloud computing, cloud storage networks, etc. NEM Engine Tech can provide you with 10g from 1m to 15m SFP + high speed cable.
1 SFP + high-speed cable = (2 SFP + 10 Gigabit optical modules + 1 pair of OM3 10 Gigabit optical fiber cable)
But in terms of cost SFP + cable can save about 50% of the cost, so it is favored by data center cabling.
