Focus on MTP-link

Characterized by providing ideal plug-and-play solutions for structure cabling, pre-terminated cabling system has gained great popularity among data center manager in recent years, and it is considered as the norm for data center network deployment. In this cabling system, optical link is accomplished by pre-terminated cabling assemblies, such as MTP/MPO trunk cable, MTP/MPO to LC breakout cable, MTP/MPO cassette and MTP/MPO fiber optic patch panel. It not difficult to find that all these MTP/MPO fiber optic cable assemblies are based on the structure of MTP/MPO connector. And two types of MTP/MPO connectors—12 fiber MTP connector and 24 fiber MTP connector are commonly used for 40G and 100G transmission. This article will focus on MTP-link and share share some opinions about MTP-link performance with you.

About Space Utilization

High-density cabling makes the available space in data centers always precious. MTP/MPO fiber optic cable assemblies used in MTP-link that contributes to promoting space utilization are reputably appraised by data center managers. With massive cables being adopted in the data centers to carry out data transmission, MTP-link offers cabling solutions with much higher density and flexibility for data center upgrades.

About Insertion Loss

As well know that insertion loss is inevitable during the cabling. Generally, lower overall optical loss allows more margin for the network to operate, or in the case for some users, offers the option of more connections for patching locations. Therefore, components characterized by low insertion loss will be preferred. For both 12-fiber and 24-fiber MTP/MPO connector performance, the industry standard product rating is 0.5 dB maximum. And using low-loss ferrules, both 12 fiber MPO connector and 24 fiber MPO connector can be rated at 0.35 dB maximum. What’s more, there is no need to worry about higher fiber count will lead to higher insertion loss, because when using proper polishing techniques, 24-fiber MPO/MTP terminations can meet the same performance levels as 12-fiber MPO/MTP assemblies.

About Fiber Utilization

Both 12-fiber MPO cable and 24-fiber MPO cable can be used in 100G applications. When used in 4x25G solutions, 4 fibers of 12-fiber MPO cable will remain unused. As for 24-fiber MPO cable, it can be converted into three 8-fiber 100G channels that run over one cable, with all 24 fibers used to support data transmission. Maybe you feel confused about this, let me take an example. If you need to support twelve 100G channels with the 4x25G standard, by using 12-fiber MPO cable, you will need to install 12 connectors, or 144 fibers total, with 33% of the fiber wasted; while by using 24-fiber MPO cable supporting the same 12 channels, only 4 cables would be required, using 96 fibers total, at 100% fiber utilization.

About Network Performance

It is self-evident that MTP-link offers consistent high levels of network performance for improved network integrity, because the assemblies are factory terminated and the transmission testing is performed by the manufacturer before shipment. This will reduce the likelihood of many problems that may occur with field terminations. Also, testing and troubleshooting time can be greatly saved.

Conclusion

By using MTP components, MTP-link can provide fast installation, high density and high performance cabling for data centers. As 40G and 100G Ethernet is now a trend and hotspot for data center cabling system, MTP-link is a great option for data center managers and the network deployment will benefit a lot from this cabling solution. I hope after reading this article, you can have an in-depth understanding of MTP-link.

Know More About Pre-terminated Trunk Cable Assemblies

In high-density data center environments, the ability to install cabling systems rapidly can save both time and money. Pre-terminated trunk cable assemblies provide ideal plug-and-play solutions for structure cabling—pre-terminated cabling solutions. These solutions simplify the design and installation of network services by providing high-density, end-to-end systems that deliver quick, plug-in network deployment. This article will guide you to know more about pre-terminated trunk cable assemblies.

Two Types of Pre-terminated Trunk Cables

Corresponding to fiber-based network deployment and copper-based network deployment, there are pre-terminated fiber cabling and pre-terminated copper cabling. The following part will introduce two types of commonly used pre-terminated trunk cable assemblies: pre-terminated fiber trunk cable, and pre-terminated copper trunk cable.

MTP/MPO Trunk Cable

Pre-terminated with MTP MPO connector on both ends, MTP/MPO trunk cable is a cost-effective alternative to time-consuming termination that improves reliability and reduces installation time and cost. It is capable of providing rapid deployment of high density backbones cabling in data centers and other high fiber environments. In networking applications, 12-fiber and 24-fiber MTP/MPO trunk cables are commonly used: 12-fiber MTP/MPO trunk cable is normally for 40G Ethernet network, while 24-fiber MTP/MPO trunk cable is normally for 100G Ethernet network. Since there are different types of MTP/MPO trunk cables on the market, it is important to choose the suitable one provided by reliable MPO trunk cable manufacturers. The following figure shows a high fiber count MTP/MPO trunk cable—72-fiber MTP/MPO trunk cable. There are 6 legs on both ends with each leg terminated with a 12-fiber MTP MPO connector.

Pre-terminated Copper Trunk Cable

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. It allows fast and easy installation with reduced labor costs in large copper infrastructures with high-density cross-connection and patching systems. In recent years, this high-performance trunk cable has become a popular plug-and-play solution in the horizontal distribution area (HDA) to connect switch cabinets to server cabinets, and in the zone distribution area (ZDA) to run from the HDA to zone boxes. The pre-terminated copper trunk cable assemblies on the market are available in 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. Here is a figure of pre-terminated copper trunk cable for you.

Benefits of Pre-terminated Trunk Cable Assemblies

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

High Speed of Deployment

The high speed of deployment offered by pre-terminated trunk cable assemblies is an equally important feature. The quick plug-in connections of network devices allow fiber and copper links to be installed in significantly less time than traditional field-terminated links, resulting in considerable installation-cost reductions. In many cases, pre-terminated trunk cables can cut installation time by up to 80% over field terminations.

Consistent High Levels of Performance

Pre-terminated trunk cable assemblies offer consistent high levels of performance for improved network integrity. Solutions are available that exceed specifications for high data transmission rate performance, providing extra headroom in the channel for data center upgrades and modifications. This level of reliability is crucial in the data center environment, where channel insertion loss budgets are very tight.

No Need for Performance Testing

The transmission testing of pre-terminated trunk 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.

Cut Clean-up Time

Pre-terminated cabling 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.

Conclusion

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. They can accelerate the process, reduce costs and errors, and can help bring your data center online in less time. If your data center or network application needs speed and testing simplified installation, pre-termination trunk assemblies are perfect.
