Data Center Pre-terminated Copper Trunk Cable Solution

Updated on Nov 21, 2019 by

Fiber optic cables, with their benefits of longer transmission distance and less EMI, have been highly recommended to use as the next generation media of data transmission. However, within a data center, copper cables are still considered as an ideal solution as they can offer significant advantages in terms of capital expenditures, operating expenditures, and reliability. Pre-terminated copper Ethernet trunk cable, as a new copper cabling option for fast-and-easy deployment in permanent link trunks and equipment port harnesses of data center architectures are recommended in this post with interconnect and cross-connect applications.

Overview of Pre-terminated Copper Ethernet Trunk Cable

Pre-terminated copper Ethernet trunk cables are commonly used in point-to-point connections in data centers, such as achieving reliable connectivity between server and switch cabinets. And copper patch cords are however used to connect panels to switches and servers. With factory pre-terminated and tested parts, the pre-terminated copper cable assemblies can help users save time and reduce jobsite waste, which are ideal solution for data centers and other applications where speed of installation is important.

Different Types of Pre-terminated Copper Ethernet Trunk Cable

Various of termination types are available for the per-terminated trunks, such as jack-to-jack, jack-to-plug, plug-to-plug, and so on. Therefore, you need to choose the most proper one based on the layout of the data center or telecommunications room, and the design philosophy employed.

Jack-to-Jack Ethernet Trunk Cables

Deploying jack-to-jack pre-terminated copper Ethernet trunk cables requires the use of empty patch panels on each end. Patch cords would then be used to complete the channel between active equipment (i.e. servers and switches). Many users prefer to employ cross-connects instead of direct connections.

Plug-to-Plug Ethernet Trunk Cables

Plug-to-Plug copper cables are used to make a direct connection between active equipment (e.g. server to switch). It eliminates cross-connect capabilities, which is not necessary but a recommended practice. Also can be used in an open-space work area as a bundled patch cord group. Although trunks are more aesthetic in appearance, the use of multiple standard patch cords is more cost effective.

Pre-terminated Copper Cable Assemblies Use Case

As mentioned above, pre-terminated copper cable assemblies can be used in data center for backbone or intra-rack cable connectivity. This section illustrates the interconnect and cross-connect connectivity with them in universal data center cabling applications.


In general data center cabling, copper Ethernet trunk cables are used to make a permanent link between patch panels on each ends—one end is in a switch/network cabinet, and the other end is in a server/storage cabinet. And patch cords are usually used to interconnect the active equipment such as switches, servers, etc., as the following picture shown:


Cross Connect

In the cross-connect cabling configuration, as shown below, an individual patching area (often including two or more adjacent patch panels) is usually added between the switch/network cabinet and server/storage cabinet. Thus, two copper Ethernet trunk cables are used as two permanent links between them. One runs from the switch/network cabinet panel to cross-connect panel, and the other one runs from cross connect panel to the panel in the server/storage cabinet. Copper patch cords are used to interconnect the active equipment and patch panels at the switch/network cabinet, cross-connect cabinet, and server/storage cabinet.

Pre-terminated Copper Ethernet Trunk Cables And Fluke Test

Pre-terminated copper Ethernet trunk cables offered by FS.com have passed fluke test, which ensures reliable performance and high quality of our cables. Then Why Ethernet cables should better pass fluke test? So what exactly is fluke test? In fact, fluke test is supported by Fluke Corporation—the most commonly known manufacturer of cable testing equipment. Fluke test checks for cable performance. When testing a specific cable, the chief reason it is used for is to check to what length the cable meets performance standards per particular cable type (cat5e, cat6, etc.). It also checks resistance (ohms), insertion loss margin (dB), frequency (MHz), prop. Delay (ns), delay skew (ns) and limit (dB). While checking each of the pairs, the fluke test looks for the amount of noise (interruptions) present during data transfer, indicating if this noise is within industry standards.


FS.com offers a wide range of configurable pre-terminated copper Ethernet trunk cable assemblies and patch panels to meet your demands on significantly faster deployment and guaranteed performance in data center copper cabling, help saving time and money.
