What Is Fiber Optic Trunk Cable Assemblies

Pre-terminated trunk cable assemblies provide an ideal plug-and-play solution for links between switches, servers, patch panels, and zone distribution areas in the data center. Compared with field-terminated cabling, the pre-terminated cable assemblies can accelerate the process, reduce costs and errors, and can help bring your data center online in less time. This article will tell something about pre-terminated cabling.What Can Pre-terminated Trunk Cables Achieve?

There are many benefits of deploying pre-terminated cable assemblies.

• Increase Speed of Deployment

Field termination is the most time-consuming, labor-intensive part of the cable installation process. Once pre-terminated cable assemblies are delivered, they are ready for deployment, and can be connected quickly. In many cases, pre-terminated cables can cut installation time by up to 80% over field terminations.

• No Need for Performance Testing

The transmission testing of pre-terminated cable assemblies is performed by the manufacturer before shipment, and test reports are included with the assemblies. This leaves only continuity testing for copper and 10% insertion loss and continuity testing for fiber, which reduces the time spent testing on-site.

• Reduce Downtime With Faster, More Flexible MACs

With pre-terminated solutions, data center managers can make changes quickly based on network growth, business decisions, or shifting requirements. In disaster recovery situations that call for fast, temporary data communications set-up, pre-terminated cabling can minimize business downtime and establish communications quickly. It can be disassembled quickly when the situation is resolved. The components are reusable for more efficient moves, adds, and changes (MACs).

• Cut Clean-up Time

Pre-terminated solutions allow for quick clean-up due to minimal leftover materials and scrap. Also, because there is less waste material to clean up, pre-terminated solutions also help meet green design, waste reduction, and material reuse goals.Common Types of Pre-terminated Trunk Cables

There are pre-terminated fiber cabling and pre-terminated copper cabling. This part will introduce two kinds of commonly used pre-terminated trunk cable assemblies: pre-terminated fiber trunk cable, and pre-terminated copper trunk cable.

• MTP®/MPO Trunk Cables

Pre-terminated with MTP®/MPO connectors on both ends, the MTP®/MPO trunk cables provide a quick-to-deploy, scalable solution that improves reliability and reduces installation time and cost. They are capable of supporting multiple users or devices from one point to another while distributing multiple data channels, which is a convenient and economical alternative to running multiple jumpers or patch cables. Generally 12-fiber MTP®/MPO trunk cables and 24-fiber MTP®/MPO trunk cables are commonly used separately for 40G applications and 100G applications. The following picture is a 12-fiber female to female MTP® single-mode trunk cable.

There are also high fiber count MTP®/MPO trunk cables which have several legs on both ends. The following picture shows a 72-fiber MTP®/MPO trunk cable. There are 6 legs on both ends with each leg terminated with a 12-fiber MTP®/MPO connectors.

• Pre-terminated Copper Trunk Cables

The pre-terminated copper trunk cable is a bundle of category cables, built with a choice of 6, 12, or 24 cable bundle and factory terminated with jacks and plugs. They allow fast and easy installation with reduced labor costs in large copper infrastructures with high-density cross-connection and patching systems. The pre-terminated copper cable assemblies offered by FS.COM are pre-bundled and pre-labeled styles, available in Cat 5e, Cat 6 and Cat 6a UTP and STP cable constructions with each available in jack to jack, plug to plug and jack to plug termination ends.

How to Choose the Suitable Pre-terminated Trunk Cables?

When selecting pre-terminated cable assemblies, the following tips are for your reference.

• Be sure to use a reliable vendor that can offer services such as guaranteed cabling performance, design assistance, certified contractor training, and the ability to support large quantities of assemblies in the required delivery window.
• Make sure the pre-terminated fiber or copper cabling purchased through a manufacturer uses components that have been tested and verified by a third party to exceed TIA and IEEE standards. The manufacturer should also provide 100% testing in a quality-controlled environment before the cabling is shipped out to the work site.

Summary

Pre-terminated trunk cable assemblies are perfect for data centers and other applications where speed and testing simplify installation. They help to save time, and labor.

Overview: Fiber Optic Trunk Cable Assemblies are high‑density, pre‑terminated cable systems that integrate multiple fiber strands within a single, organized assembly. They are factory‑terminated with precise connector‑endfaces for easy plug‑and‑play deployment in data centers, backbone cabling, and high‑performance networks. Designed to optimize installation time and ensure loss‑controlled connectivity, these trunk assemblies deliver superior mechanical protection and optical performance for large‑scale structured cabling systems.
