Application of 10 Gigabit Copper Cable Cabling System in Communication Between Buildings

CNPS is a communication system for a government office building in a West African country constructed by a Chinese construction company. It is made up of departments from 7 different government ministries. After using a lot of data analysis and comparison of optical fiber, Cat6a copper, CNPS consider use Cat6a copper cable and 10GBASE-T transceiver to support 10G network system. From this scheme, we can understand the application of Cat6a copper cable and 10GBASE-T module through real cases.

Why Choose the Cat6a Cable and 10GBASE-T Modules?

From the perspective of the transmission distance of the optical fiber system, optical fiber transmission is an ideal solution to realize the backbone of the 10G network in the entire office building. However, in the horizontal work area, the transmission distance from the data center to each work point is short, and the transmission distance is within 100m. The transmission distance of Cat6a copper cable is 100m, which can meet the cable design requirements. In terms of price, the network solution for optical fiber transmission of 10 Gigabit Ethernet is to use 10GBASE-SR optical fiber modules, but the cost per port of 10GBASE-T network modules is only half of 10GBASE-SR, 10GBASE-ER/EW 1/10, or even lower. Therefore, the copper cable and 10GBASE-T transmission 10G network have a great price advantage over the optical fiber transmission.

The Detail of Copper Cabling System 

By comparing the transmission distance and the price, it can be concluded that the Cat6a copper cable is an ideal solution for 10 Gigabit Ethernet within a transmission distance of 100m. Cat6a copper cable can realize transmission distance more than 100m and less than 300m, such as the network backbone between buildings in the building or the vertical network backbone in the building, and the intercommunication between the outside and the metropolitan area network, etc. 12-core indoor single-mode fiber optic cable (9/125) is used for communication between buildings. At the same time, the unshielded copper cable is selected here instead of the shielded copper cable, which is mainly because the shielded wiring has higher requirements for construction and grounding.

The Advantage of Using 10GBASE-T Transceiver

This solution can fully meet the connection requirements of 10G BASE-T network equipment within a transmission distance of 100m, can support 10G connections, and obtain more bandwidth capacity. The main driving force for the emergence of 10 Gigabit Ethernet is to reduce the networking cost of 10 Gigabit Ethernet as the most basic standard. For the measurement of Gigabit Ethernet technology, we use 3 times the cost to achieve 10 times its performance. The requirement of a 10 Gigabit network is still to use 3 times the cost to achieve 10 times the performance to measure 10G BASE-T as the technical standard. For the implementation of 10 Gigabit Ethernet in the horizontal work area, Cat6A copper cabling can provide a more economical cost than optical fiber for 10GBASE-T channels, and the RJ45 interface is used, which is low in cost, convenient in construction and installation, and has good compatibility.

This solution uses 10GBASE-T modules and Cat6a cables to establish 10G Ethernet transmission between buildings while saving a lot of costs and meeting the communication needs between buildings. Through this solution, we can understand how to apply the 10GBASE-T module and Cat6a cable. If you have questions about 10GBASE-T modules and Cat6a cables, you can contact QSFPTEK via sales@qsfptek.
