Twin-Axial Cable is certainly another type of co-axial cable, slightly different in construction. In the coaxial cable, only one conductor is insulated inside the cable whereas in twin-axial cable there are two conductors enclosed inside the cable.
High-Speed Data Transmission
By the advancement in modern technology, the most important factor is the transmission of high-speed differential signals. To meet the data rate of the equipment’s, twin axial cables are used.
Twin-Axial Cable provides a balanced transmission among the devices. It also has the ability to address multiple devices altogether using the same cables.
The signals that are sent using twin-axial cable are usually transmitted using signal coding. The most common signal coding used while transmitting the number of bits would be Manchester coding. The basic idea behind the transmission of differentially balanced signal that two signals are being transmitted at a particular rate.
Following are some of the applications of twin-axial cable
1) SFP + Direct Attach Copper
It is used for Direct Access housing to improve signal integrity. Twin-Axial cables that are shorter than 5 meters in length are passive and the ones which are longer than 5 meters are active. It is mostly used for the 10 Gigabit Ethernet Cable. This cable has the potential of transmitting 10 Gigabits per second over a distance of 5 meters less or more.
2) 100 Gbit Ethernet
Another usage of the twin-axial cable is in the manufacturing of 100 Gigabit Ethernet Cable. Mostly, the cable is 7 m in length and meet the specifications of the IEEE 802.3 standards.
3) SATA 3.0 cables
Twin-axial cables are also used in the manufacturing of SATA 3.0 cables. The SATA cable provides better transmission rate.
DisplayPort cabling is also using Twin-axial configuration in their cables to reduce the insertion losses, return losses, and increasing the data transmission rate up to 2.7 Gbit/seconds.
