The development of high-speed Ethernet has never stopped from 100m, 1G, 10G to 40G and 100G in data center network. The 10G Ethernet (IEEE802.3ae) standard was approved in 2002. in 10G networks, engineers need to consider whether to choose optical fiber or copper cable in wiring, and everyone wants to choose a cost-effective solution. Next, ETU-LINK analyzes 10G SFP+ DAC high-speed cable and 10G SFP+ optical module in detail. I believe you can know how to choose through this article.

10g SFP+ DAC high speed cable

10G SFP+ high-speed cable is a common optical device for top-of-rack wiring in data centers, which is used to connect small access switches and servers. 10G SFP+ high-speed cable is a low-cost solution instead of optical module, which is used to realize short-distance high-speed interconnection and has the characteristics of low power consumption and low delay.

10g SFP+ optical module

The SFP+ optical module is a duplex LC interface used with LC optical fiber jumpers for optical fiber cabling. It provides a variety of 10G Ethernet connection options for data centers, enterprise wiring closets and service provider transmissions, usually at 850nm 1310nm or 1550nm.

10g SFP+ electric port module

The 10GBase-T SFP+ optical module uses unshielded or shielded twisted pair cables for 10G connectivity at distances up to 30 meters for copper cabling, and 10GBase-T SFP+, allows easy upgrade from 1GbE to 10GbE. The 10GBASE-T SFP+ optical module is used because the network cable is still common and the network cable is cheaper than the optical fiber jumper, but if the transmission distance is greater than 30m, it is still necessary to use the optical fiber jumper to connect.

Does 10G SFP+ DAC high-speed cable have an advantage over 10G port module?

① 10G SFP+ to SFP+ high-speed cable ensures the best optical performance and the lowest signal delay. In the trend of data centers, wired infrastructure can be supported to handle latency-sensitive applications anywhere. Comparing 10G port module technology with alternative SFP+ technology, it is obvious that SFP+ technology is the technology that can ensure the lowest latency and best performance in the data center.

② 10G SFP+ to SFP+ high-speed cable, reducing power consumption. SFP+ technology provides much lower power consumption than 10GBase-T technology. When the cable deployment in the data center increases from 1000 to 10000, there will be more significant cost savings, and this solution will be more economical.

The 10G SFP+-to-SFP+ high-speed cable solution is based on SFP+ MSA (Multi-Source Protocol) and uses copper axis cables with SFP+ connectors at both ends to provide 10 Gigabit Ethernet connectivity between two network devices. In short, it integrates SFP+ connectors with copper axis cables and is a low-loss, energy-efficient and low-cost interconnection solution. 10g 10 Gigabit SFP + to SFP+ high speed cable has a variety of optional lengths up to 15m, which is the best cable choice for 10 Gigabit Ethernet connection at present.

Now to straighten out for you, the first choice for short-distance transmission in 10G data center is 10G SFP+ high-speed cable, followed by 10G SFP+ optical module.

Etulink.com provides a cost-effective high-speed direct connection solution for data center interconnection, which effectively reduces signal delay and power consumption, and can significantly reduce procurement costs for you.
