Data center network from the original 100M, 1G, 10G, to 40G and 100G, the development of high-speed Ethernet has never stopped. 10G Ethernet (IEEE802.3ae) standard was approved in 2002, in 10G networks, engineers need to consider when choosing fiber optic cabling or copper, we all want to choose a cost-effective solution. Next Easy daylight Communications (ETU-LINK) is a detailed analysis of all 10G SFP + DAC cable and high-speed 10G SFP + optical module, we believe we will be able to know how to choose this article.
10G SFP + DAC high-speed cable
10G SFP + high-speed data cable is a conventional optical device center top of the cabling, connected to a small scale access switches and servers. 10G SFP + high-speed optical cable module is an alternative low-cost solutions for high-speed short-distance interconnects , low power and low latency characteristics.
The optical module 10G SFP +
SFP + optical module for use with duplex LC fiber optic cabling interfaces, and LC optical fiber jumpers. It is for the data center, enterprise wiring closets and transport service providers offer a variety of 10G Ethernet connectivity options, usually transmission wavelength is 850nm, 1310nm or 1550nm.
Electrical module 10G SFP +
10GBase-T SFP + optical module unshielded or shielded twisted pair cables to achieve 10G connection for copper cabling, using 10GBase-T SFP +, can easily upgrade from 1GbE to 10GbE in the case where the distance up to 30 meters. Use 10GBASE-T SFP + module is due to the optical cable is relatively common and the network cable fiber jumpers cheaper price, but if the transmission distance is greater than 30m, then it is to use fiber jumper connection.

10G SFP + DAC high-speed cable do have an advantage over 10G electrical interface module?
①10G SFP + SFP + high-speed transfer cable, ensure optimum performance and lowest optical signal delay. In the trend in data centers, wired infrastructure to support delay-sensitive applications anywhere in the process. Comparative 10G module technology and alternative electrical interface SFP + technology, it is apparent, SFP + art technology is able to ensure the best performance and the lowest latency in the data center.
②10G SFP + SFP + high-speed transfer cable, power consumption is reduced. SFP + technology provides a power consumption much lower than 10GBase-T technology. When the cable deployment in the data center from 1000 increased to 10,000, and can be more obvious cost savings, this solution will be more economical.
10G SFP + SFP + high speed transfer cable SFP + solution is based on the MSA (Multi Source Agreement), having both ends with SFP + coaxial cable connector is provided between two Gigabit Ethernet network connection devices. Briefly, it integrates SFP + connector and coaxial cable is a low-loss, low-cost and energy-efficient interconnect solutions. Gigabit SFP + 10G high speed rotation SFP + has a variety of cable lengths available up 15m, is the best choice Gigabit Ethernet cable connection.
We now briefly to straighten out the transmission of the first selected short-distance data center 10G 10G SFP + high speed cable, light followed 10G SFP + module.
High-speed data center interconnect easily daylight communication (etulink.com) provides direct-attach solution cost-effective, reduce signal delay and power consumption, and you can significantly reduce procurement costs.
