Tag: MPO

With the rapid development of data centers, applications such as cloud computing and cloud storage have gradually penetrated various industries, and the bandwidth requirements for network communication have also increased rapidly. High-speed, high-capacity, and high-bandwidth often require more space and higher costs. This long-term contradiction, MTP / MPO fiber wiring standard has become the best solution for high density and high bandwidth. There are two kinds of fiber optic connection systems, MTP and MPO, which are very similar in the market. They are compatible with each other to a certain extent, so what is the difference?

　　MPO (Multi-fiber Pull Off) is the first generation of shrapnel-type multi-core fiber optic connectors designed by NTT Communications Corporation of Japan. It is now the name of a multi-core connector produced by several companies. MTP, a brand registered by USConec, specifically refers to the unique type of MPO connector it produces.

　　What is an MPO connector?

　　MPO is the abbreviation for “multi-fiber pull off”. The ferrule of this connector has more than one core and is mechanically snapped into place.

　　Nowadays, various manufacturers in the market have a variety of MPO designs. The performance and cost of different types of connected products are very different. Some products make their performance more outstanding. Some MPO connectors can match many different brands of products, but some do not. This compatibility depends on how close these connectors are to standard products. For a complete definition of the MPO connector, please refer to the implementation of IEC-61754-7 and EIA/TIA-604-5 (aka FOCIS 5).

　　What is an MT ferrule?

　　The MT is a mechanical docking transmission with a multi-core number (usually 12 cores). The performance of the connector is determined by the accuracy of the fiber alignment and whether the alignment accuracy is stable after the connection. Ultimately, this alignment accuracy is determined by the eccentricity and spacing of the fiber and the matching accuracy of the guide pin and fiber. The performance of any MPO connector can be improved if the deviation of the guide pin and the molding process can be reduced during the production process.

　What is an MTP? Fiber Connector?

　　The MTP connector is a high-performance MPO connector with multiple innovative designs. The MTP fiber connector is enhanced in optical and mechanical performance compared to conventional MPO connectors. The MTP connector is fully compliant with the professional standards of all MPO connectors, including EIA/TIA-604-5 FOCIS 5 and IEC-61754-7.

　　MPO-type connectors are industry-standard, interchangeable MTP connectors, which means that it is possible to replace MPO connectors with MTP connectors for better performance. Most of the MPO connectors that follow the old design have quite limited performance and do not provide the same high performance as MTP fiber connectors.

　　Why is the MTP connector described as a high-performance MPO connector?

　　The performance and usability of the specially designed MTP connector are improved compared to the MPO connector. This design feature of MTP is unique and patented. The main features are as follows:

　　1. The outer frame of the MTP fiber optic connector can be easily removed.

　　The MT ferrule design ensures performance without loss during rework and regrinds during production. Yin-positive can be flexibly changed even after assembly, and the ferrule can be over-interfered after assembly.

　　2, MTP fiber optic connector floating ferrule can improve the transmission performance when mechanical docking. The two connectors can be allowed to maintain good physical contact with the mating ferrules under the influence of external forces.

　　3. The elliptical guide pin (PIN) of the MTP fiber connector is made of stainless steel. The elliptical guide pin can improve the precision of the butt joint and reduce the wear of the guide hole so that the MTP fiber connector can maintain high-performance transmission more permanently.

　　4. There is a metal clip in the MTP fiber connector to fix the push ring. Specific characteristics:

　Prevent the loss of the guide pin;

　　Concentrating the pressure generated by the spring;

　　Preventing the spring from touching the friction fiber during mechanical stretching to cause damage to the fiber;

　　5. The spring design of the MTP fiber optic connector maximizes the band gap of the 12-core and multi-core ribbon applications to prevent fiber damage.

　　6, MTP fiber optic connectors have at least four standard matching parts, can be adapted to different types of fiber optic cable, more practical, including:

　　around the cable with a loose structure;

　　a ribbon cable with an elliptical outer cover;

　Ribbon bare fiber;

　　The ultra-short-tail connector is ideal for applications in tight spaces, reducing volume by 45%.

　　Can the MT ferrule be cleaned in the usual way?

　　The best way to clean the dust and oil on the MT ferrule that affects optical performance is to use an advanced dry cloth cleaning kit, such as NTT-AT OPTIPOP, which is simply because it involves only a single channel. When using the above cleaning components, the contaminants will be completely removed. On the contrary, the use of low-quality fabrics or cotton swabs can remove the contaminants on the surface of the fiber, but the dirt will still exist on the edge of the ferrule, and the ferrule end faces are easily worn, causing serious Data loss.

　　The OPTIPOP series of cleaning components are designed for yin and yang fiber optic connectors and can also be used with single core ceramic ferrules. OPTIPOP cassette and card cleaners use a refillable cleaning cloth that can be used for a long time and is less expensive to clean than traditional cleaning methods.

In the 2G/3G/4G era, mobile communications are mainly deployed in the form of voice and data services. With the coming of 5G, the advantages in transmission speed and delay have been greatly improved, enabling 5G to be launched in more aspects, such as VR/AR, autonomous driving, intelligent manufacturing, smart home, Internet of things, etc. field. In the 5G laying, the demand for fiber optic cable will also grow rapidly. Among them, the MPO/MTP cable with advantages has begun to gain more attention. This article will take a closer look at the advantages of MPO/MTP cables in 5G data centers.

　Seven advantages of applying MPO/MTP cables in the data center:

　　1. Protection of the effectiveness and safety of the investment. Although the application of MPO/MTP cable provides high requirements for the integrator’s preliminary and actual site survey capabilities, it can also fully protect the investor’s control over the project and the right to use the product. To avoid material waste and risk of project investment.

　　2. Economically applicable, in general, the MPO/MTP pre-end method does not add additional costs.

　　3. Easy to operate, easy to install, save installation time, and plug and play. We can make a simple comparison, such as laying a 288-core fiber optic cable, 3 construction workers, 2 sets of equipment, using traditional fusion fiber method, laying about 2 hours, and the time required for the fusion fiber plus installation is about 8 Hours, a total of about 10 hours, and if the MPO/MTP pre-cast cable is used, the laying time is still 2 hours, but the installation time is greatly reduced, only about 45 minutes, which undoubtedly has a huge advantage in time cost.

　　4. The MPO/MTP pre-cast cable is fully tested in the factory, and no other products are added during the installation process. The field test operation is simple.

　　5. The fiber link protection is sufficient. No solder joints and bare fibers are exposed to the air, and there are no problems such as aging and joint breakage.

　　6. Maintenance is convenient and safe. The mechanical performance of the MPO/MTP pre-end cable splitter is excellent, and the maintenance or operation process will not affect the normal use of the fiber.

　　7. Re-installable and mobile, the splitter of the MPO/MTP pre-cable cable can be quickly inserted and removed and reinstalled as needed.

　　Compared with ordinary fiber optic cable, the main features of MPO/MTP cable are high density and pre-formed end, and finally embodied in MPO/MTP multi-core connector. Throughout the development of the industry, fiber optic connectors have two distinct stages of development: the first phase is to save space and to the direction of miniaturization, fiber optic connectors have evolved from traditional FC, ST, SC to LC, MTRJ. The second phase is not only to save space but also to meet the requirements of multi-core use, fiber optic connectors evolved from LC, MTRJ to MU, MPO/MTP.

　　With the rapid development of 5G, data center interconnection, fiber sensing, and next-generation fiber technology, ultra-large capacity, ultra-high-speed, ultra-long-haul optical transmission networks will become a must for 5G data center construction. Conditions, the dual advantages of MPO/MTP cable in terms of technology and cost are likely to become the mainstream way for operators to build 5G data centers in the future.

Mobile communication network news, MPO/MTP high-density optical fiber pre-connection system is currently mainly used in three areas: high-density environment applications in data centers, fiber-to-building applications, optical transceivers in optical splitters, 40G, 100G SFP, SFP+, etc. Connection application inside the device. This article focuses on why data centers use MPO/MTP high-density fiber pre-connection systems and how to choose such high-density fiber pre-connection systems.

　　Before introducing the current use of MPO/MTP high-density fiber pre-connection systems in these situations, it is necessary to make a brief introduction to MPO/MTP. In the field of communication and data transmission, the development of optical fiber connectors is far more developed than the development of copper connectors. According to incomplete statistics, so far, hundreds of fiber optic connectors have been developed, but there are more than a dozen that are actually used in a wide range. Throughout its development, fiber optic connectors have two distinct stages of development:

　　The first stage: in order to save space and develop towards miniaturization, fiber optic connectors have evolved from traditional FC, ST, SC to LC, MTRJ, E2000

　　The second stage: not only to save space but also to meet the requirements of multi-core use, fiber optic connectors evolved from LC, MTRJ, E2000 to MU, MTP/MPOFIBER CABLING, now an MTP/MPO multi-core connector can meet 2 cores, 4 cores , 8-core, 12-core, 24-core, currently up to 72 cores.

　　The benefits of this development in the second phase are obvious. Look at the 40G and 100G requirements for fiber-optic network transmission specifications. Multi-core transmission, that is, 8-core or 20-core. In this way, MPO/MTP FIBER CABLING can meet the requirements of high-speed network applications in a small space. However, engineers who work on the site also bring great challenges and even impossible tasks. Of course, there is now a good alternative, which is the pre-connected system of the manufacturing plant.

　　The application of the MPO/MTP fiber pre-connection system in the data center has also been a matter of the past few years, and it is also the most important application of the MPO/MTP pre-connection system in China. The reason is not as noble as imagined, but it is actually an inevitable choice. Let me talk about the first reason: the data center space is always not enough. Just like the completion of Beijing’s subway for half a year, passenger traffic is full. This is actually a contradiction between limited resources and unlimited demand. This phenomenon is manifested in various fields in China today. To solve the problem of insufficient space, you can increase the space or increase the utilization of space. It is unrealistic to increase space in a designed data center. Increasing the space utilization rate means increasing density. As the two major wiring systems in the data center: copper cables, cable cabling systems, in fact, copper systems can also use high density, but this high-density space savings are limited. Because it is not only impossible to find a balance between the high frequency and the larger line; the electrical transmission performance of the cable at high frequency is not easy to meet, and the high-frequency electronic signal is also transmitted in the multi-core copper transmission. A series of questions. Of course, in order to install a convenient copper pre-connection system on site, this is another topic, no matter here. Therefore, in order to get more transmission bandwidth in the same space, switching to optical cable transmission is an inevitable choice, but this does not mean that a high-density optical fiber pre-connection system is required.

What is the MTP fiber patch cord?

MTP stands for Multi-Core Termination Push-In Connector, designed by Conec USA, and is a high-performance MPO connector with multiple innovative designs. The name of the MTP fiber patch cord comes from the MTP connector and is used for high-density connections between telecommunications room network equipment. This fiber patch cord provides a cost-effective solution for cabling systems with high performance, high density, and many other advantages.

MTP fiber jumper structure

MTP fiber patch cords are made up of MTP connectors, fiber optic cables, and other connectors, such as LC connectors or some MTP fiber patch cords. Fiber optic cables typically use OM3 and OM4, which are laser-optimized multimode fibers. Unlike traditional connectors, MTP/MPO connectors should be used with care to ensure proper connections.

MTP fiber patch cord type

According to different standards, MTP fiber jumpers are divided into multiple types. According to the number of cores, MTP fiber jumpers are divided into MTP single mode fiber jumpers and MTP multimode fiber jumpers. According to the connectors at both ends, there are mainly two configurations of MTP fiber jumpers. One is the MTP connection MTP, commonly referred to as the MTP backbone fiber patch cord. The other is MTP connected to a standard LC / FC / SC / ST / MTRJ connector (usually MTP-LC), which is commonly referred to as MTP branch fiber patch cord or MTP fan-out fiber patch cord.

Advantages of MTP fiber patch cord

The MTP fiber system is a truly innovative batch of products. The compact design of the MTP connector allows the MTP jumper core to be numerous and small, and the most commonly used are 12-core and 24-core. It is the same size as an SC connector and can deliver up to 12 fibers or 24, saving on circuit cards and rack space.

 

With the MTP trunk jumper, a complete fiber backbone can be installed without requiring any field termination. In addition, the MTP connector is fully compliant with all MPO connector standards and is compatible with VZ TPR.9431, IEC-61754-7, and EIA / ti A-604-5 and can be used to replace MPO connectors for better performance… It uses a simple push-pull latching structure for easy and intuitive insertion and removal.

MTP fiber patch cable application

MTP fiber patch cords can be used in a wide variety of applications. Such as backbone network, fiber optic wiring, high-density data center environment, warehouse, ribbon cable terminal, fast maintenance setup and playback system solutions, and parallel optical interconnection between servers.
