Data centers are consistently undertaking their own migration. Especially when 40G/100G/400G network has become an irresistible tendency, which also brings the quest for greater bandwidth and higher density optical connectivity – the increased port density, therefore, drives escalating power consumption. The following chart indicates the proportion of Ethernet ports over the years. So, if it’s possible to reach a balance between high capacity and low power consumption? – MTP/MPO technology makes this challenge viable by offering a constructive and reliable solution.


With the continuous drive of the application and popularization of the network media in the cloud computing environment, the multimode fiber jumper is also developing, from OM1  to OM2, and from OM3 to OM4 to use the VCSEL laser optimization technology, the bandwidth demand is increasing. New OM4 Multi-mode jumper fiber standard EIA/TIA492AAAD is introduced, which provides a better transmission mode for multimode fiber in the future wide application. This article provides an ideal communication solution for your data centre, servers, network switches, telecentres, and many other embedded applications that require high-speed data transmission.

Fiber optic jumper applications in the data centre are very extensive, and in recent years the data centre fiber optic transmission system bandwidth demand shows a high growth trend, so the use of a new generation of fiber and optical modules can continue to explore the potential of fiber-optic network bandwidth growth. As the multimode fiber jumper in the cost of a great advantage, to promote its application in the data centre.

In a transport port connection device in a 40G / 100G /400G data transmission application, such as QSFP optical modules, regardless of Fiber Channel connections using several fiber connections, and regardless of the type of fiber connection, they are connected directly to the MTP® / MPO connector. Because the 40G / 100G data transmission application channel and the device connection between the equipment need to form a special mode, so that the device’s transmitter and receiver channels corresponding to each other, which requires MTP® / MPO connector to complete the connection.


The MPO/MTP® fiber jumper can provide a wide range of applications for all networks and devices that require 100G modules. They use the high-density multimode fiber optic connector system MT series of casing design, MPO / MTP® fiber jumper with UPC and APC polished end and supports multimode and single-mode applications. The 10G OM3 / OM4 MPO / MTP® fiber jumpers provide 10 Gbps of data transfer rates in high-bandwidth applications, which are five times faster than the standard 50 μm fiber jumper.

At the same time, multi-mode MPO / MTP® fiber jumpers are also the most economical choice for most of common optical fiber communication systems. Single-mode MPO / MTP® fiber jumper is mainly used for long-distance data transmission system. The MPO / MTP® trunk cable is designed for data centre applications. Typically, single-mode and multi-mode MPO / MTP® fiber jumpers are designed to be 3mm or 4.5mm round cable, and connectors at both ends of the cable are also referred to as MPO / MTP® connectors.

The MPO / MTP® high-density push-pull fiber jumpers are currently used in three areas: high-density cabling data centres, fiber-to-the-home, and connection applications with a splitter, 40G QSFP+ / 100G QSFP28, 10G SFP+ and other optical modules. Today, there are already a series of high-density parallel optical interconnect products that can accommodate optical fiber transmission in modern data centres, such as custom MPO / MTP® fiber jumpers, multimode fiber loopers, and QSFP+ high-speed cable assemblies.


Server virtualization and the development of cloud computing, as well as the development trend of network convergence, bringing a faster and more efficient data centre network development needs. At present, 48x 10G channel composed of 10G switches, mainly limited to the use of SFP+ module to achieve the connection. In order to meet the higher bandwidth requirements, users can use a high-density QSFP+ high-speed cable to complete the connection, by increasing the data transmission rate of each channel and increase the port density to meet customer’s high bandwidth requirements.

Data centers have an unceasingly demand for bandwidth, yet the best way to satisfy this appetite is to keep the proliferation of fiber connection and to build ever-faster links. MTP/MPO assemblies have become the default cabling solution in data center: they are a natural fit for parallel optics. At the heart of every MTP/MPO assembly lies the MTP/MPO connector, which utilizes multiple fibers to realize optical transmission. The fibers can transmit and receive data simultaneously, which dramatically enhance the network speed and performance. The following picture takes 40G link for example to show how to achieve parallel transmission.


MTP or MPO fiber links are compact, pre-terminated, able to handle massive bandwidth (up to 400G) and even plug and play by design. Gone with the days when installers have to manage hundreds and even thousands of single- and 2-fiber connector solutions. MTP/MPO technology emerges to accommodate higher volume of connectors within ever-tighter space constraints. It significantly reduces the amount of time, effort, and space required to install and deploy network. Meanwhile the future updates, additions, and changes to the structured cabling are also simplified. The fiber density made MTP/MPO cabling a perfect fit for data centers with serious space constraints and massive cables.
