What Is the Difference: Twinax vs Twisted Pair


With the passage of time and the development of information era by leaps and bounds, the demand for more bandwidth and data transmission to satisfy the ever-increasing number of operating systems and applications is becoming a cumulatively common trend. As the media types of transmitting signals, the popularization of SFP cable and Ethernet cable/twisted pair cable have been the tendency towards data center interconnection applications and can be ascribed to the domination of Cat5e copper cabling and 1000BASE-T over the years. So in this article, we will concentrate on the brief introduction to the cables: twinax vs twisted pair and their corresponding application considerations.

Twinax vs Twisted Pair: What Is SFP Twinax Cable?

Twinax vs twisted pair: how to understand the concept? SFP cable, sometimes called as 10G SFP+ cable, SFP+ DAC twinax cable, is a kind of high speed cable with Small Form Factor Pluggable Plus on either end. SFP twinax cable which displaces two optical modules and an optical fiber with a twinaxial copper cable assembly offers the higher density, lower cost, and lower power 10 Gigabit Ethernet solution than other cable types such as 10GBASE-CX4 and CAT6/CAT6A 10GBASE-T.

Twinax vs Twisted Pair: What Is Ethernet cable?

Twinax vs twisted pair: don’t get confused with Twinax cable. An Ethernet cable, also known as twisted pair cable, is one of the most fashionable forms of network cable used in wired networks. Ethernet cable connects devices together within a local area network, such as PCs, routers, switches and normally supports one or more industry standards including Category 5 (CAT5), Category 5e (CAT5e), and Category 6 (CAT6). It can be classified into STP (shielded twisted pair) and UTP (unshielded twisted pair). Ethernet cable is applied in many situations due to its advantages of fast speed, high reliability and security.

Twinax vs Twisted Pair: Application Considerations

When you are faced with the decision of choosing between twinax vs twisted pair, the following factors have to be well considered.

Twinax vs Twisted Pair

Speed & Distance: twisted pair is normally used for 10MB, 100MB and 1GB network connections, while twinax cable goes for 10 Gigabit Ethernet Network. And twisted pair also supports much longer distance than SFP+ Direct Attach Copper cable with short range connection which measures as small as 5 m to 10 m.

Power Consumption: twinax cable uses a different signal propagation method that makes it consume much less power (something around 1-1.5W per port) comparing to UTP (4-6 W per port). So once you have a lot of ports, this power consumption can be significant factor in design. Twinax is an ideal 10GbE solution for server to Top of Rack switch connection for integrated storage and data network since the performance of low power and more reliability.

Cost: SFP twinax cable is a lower cost alternative to traditional fiber and twisted pair copper cabling in data center applications when you include switch, NIC and cable. SFP+ DAC provides better cable management for high-density deployments and enhanced electrical characteristics for the most reliable signal transmission during the process of twinax vs twisted pair.


From this article, you could have a good idea of twinax vs twisted pair. As you can see, there are always two sides to everything. However, you can still make your decisions according to the actual demand from the perspective of transmission distance, power consumption and budget. Fiberstore can provide high-quality fiber optic cable with different types and SFP twinax cable and twisted pair cable as well.
